Use WhatsApp Without Sharing Your Phone Number (2026 Guide)

Smartphone showing a messaging app with a padlock icon, illustrating WhatsApp phone number privacy

Last reviewed: October 1, 2026

Short answer: You cannot create a WhatsApp account with no phone number at all. WhatsApp's own usernames FAQ says you still need a phone number to register and use the service. What you can do is keep your personal mobile number out of view. The legitimate ways are: reserve and use a WhatsApp username as that feature rolls out, register WhatsApp on a second SIM or eSIM that you own, run a separate business account in the WhatsApp Business app (which also accepts a landline you own), and tighten the privacy settings that control who sees your profile, who can call you and who can add you to groups.

Whatever route you choose, use a number that you own and will keep. Numbers you do not control, such as shared, borrowed or throwaway numbers, are unsafe: whoever receives the next verification code for that number can take over the account. Turn on two-step verification, add a recovery email and a passkey, and never share a registration code with anyone.

This guide explains what WhatsApp needs your number for, what other people can see, and every policy-compliant option for keeping your main number private in 2026. It draws on the WhatsApp Help Center, the WhatsApp blog, WhatsApp's Terms of Service and Privacy Policy, the Meta newsroom, and guidance from the US Federal Trade Commission (FTC), the Federal Communications Commission (FCC), the UK Information Commissioner's Office (ICO) and the UK National Cyber Security Centre (NCSC). We do not recommend any carrier, phone service or app.

Why WhatsApp needs a phone number

WhatsApp uses your phone number as the identity of your account, so a number is required to sign up. The Privacy Policy states that you must provide your mobile phone number and basic information, including a profile name of your choice, to create an account.

The number does three jobs:

It proves you control the line. During registration WhatsApp sends a six-digit code by SMS or reads it out in an automated phone call. The Help Center says you must be able to receive phone calls or SMS on the number you are trying to register.
It connects you to people you already know. WhatsApp matches the numbers in your address book against registered accounts, which is why your contacts appear in the app without you adding them one by one.
It is the address messages are delivered to. Until usernames are fully launched, a phone number is the only way another person can start a chat with you.

The Terms of Service add two obligations that matter for this guide. You must register using accurate information and provide your current mobile phone number, and if you change your number you must update it using the in-app Change Number feature. The Help Center is more direct still: you can only register a mobile number, or in the Business app a landline, that you own.

What other people can see about your number

By default, anyone you chat with on WhatsApp, and every member of a group you are in, can see your phone number. The Help Center states that it is not currently possible to hide group members' phone numbers in a group, and that your number is visible to a recipient even if they have not saved you as a contact.

Situation	Can they see your phone number?	What you can control
One-to-one chat started by phone number	Yes	Profile photo, about, last seen and online, read receipts
One-to-one chat started through your username (as the feature launches)	WhatsApp says the person you message for the first time will no longer see your number if you have enabled a username	Username, optional username key, profile visibility
Ordinary group chat	Yes, all members	Who is allowed to add you to groups; leaving the group
After you leave a group or community	The Help Center says your profile name and number appear in a past members list for up to 60 days	Think before joining large groups of strangers
Following a Channel	No. Meta says following a channel does not reveal your number to the admin or other followers	Which channels you follow stays private
Messaging a business from an ad on Facebook or Instagram	The Help Center says your number is hidden from the business by default in this case	You choose whether to share it

What "WhatsApp without a number" realistically means

"WhatsApp without a phone number" really means "WhatsApp without exposing my personal mobile number." Registration with no number is not offered, and any website or video that promises it is describing either a number you do not control or an unofficial app. Both put your account at risk.

There are three honest goals people usually have, and each has a legitimate answer:

"I do not want strangers, customers or group members to have my personal mobile number." Use a username when available, a dedicated second number, or a business account on a separate number.
"I do not have a SIM in this device." A tablet, computer or second phone can be linked to an existing account as a companion device. The account still belongs to a phone number.
"I only want to broadcast or follow updates." Channels are designed so that followers' numbers are not shown to admins or to each other.

What is not legitimate under WhatsApp's rules: creating accounts on numbers that are not yours, creating accounts in bulk, or opening a fresh account to get around a ban. This guide does not cover any of that.

The legitimate options compared

There are seven official routes, and they solve different problems. Usernames hide your number in new conversations. A second SIM, a landline in the Business app, or a second account give you a different number to show. Linked devices, Channels and click-to-chat links change how you use an existing account rather than which number it uses.

Option	Hides personal number from	Still needs a number you own?	Cost (qualitative)	Main risk or limit
1. Username (plus optional username key)	People you message for the first time once the feature is live for you	Yes, to register	Free	Still rolling out; businesses' numbers remain visible; existing contacts already have your number
2. Second SIM or eSIM	Everyone you talk to on that account	Yes, the second line	Ongoing cost of keeping a line active	If the line lapses, the number can be reassigned
3. Landline in WhatsApp Business	Customers and the public	Yes, a landline without an extension	Whatever the landline already costs	Only supported in the Business app; you must be able to answer the verification call
4. Two accounts on one phone	Whoever only knows the second account	Yes, a second number	Cost of the second line	Easy to post from the wrong account
5. Linked devices / companion phone	Nobody. Same account, same number	Yes, the primary account	Free	Depends on the primary phone staying active
6. Channels (and Communities, with limits)	Channel admins and followers	Yes, to register	Free	One-way broadcast; groups inside a community still show numbers
7. Click-to-chat link or QR code	Nobody. It publishes a number in a convenient form	Yes	Free	Anyone with the link can message that number, so use a business number

Option 1: WhatsApp usernames and the username key

Usernames are WhatsApp's official answer to number privacy: an optional handle people can use to reach you instead of your phone number. As of this review, WhatsApp has opened username reservations and says the full feature is rolling out gradually, country by country. Treat anything beyond reservation as "arriving," and check your own app.

What WhatsApp has officially announced

WhatsApp's blog post "It's time to reserve your WhatsApp username," also published in the Meta newsroom in June 2026, and the accompanying usernames FAQ set out the following:

Usernames are optional. They are described as a new way to connect that gives you control over who sees your phone number in the first place.
Reservation came first. You can reserve a username on the latest version of WhatsApp under Settings > Account > Username, to use when the feature launches.
Your number is hidden in new conversations. WhatsApp says that once usernames launch, when you message a person or business for the first time they will no longer see your phone number, if you have enabled your username.
There is no directory. WhatsApp says there is no list to browse and no suggestions. People need to know your exact username to contact you for the first time.
The username key is an optional second lock. If you set one, others need both your exact username and your key to message you for the first time. The FAQ says you can reset the key at any time to stop new contacts reaching you through your username.
You still need a phone number. The FAQ answers this plainly: yes, you still need a phone number to register and use WhatsApp.
Format rules. The FAQ describes usernames as 3 to 35 characters using Latin letters, numbers, periods and underscores. A built-in generator suggests options.
Anti-impersonation rules. Well-known names are reserved for their legitimate owners, and certain words such as "bank," "government," "police" and "verified" are blocked.

What usernames do not do

Usernames do not replace phone numbers. They sit on top of them. Four limits are worth knowing:

People who already have your number saved still have it. A username protects future introductions, not past ones.
Business accounts are treated differently. The FAQ says a business can have a username, but its phone number still displays when it contacts others. If you run a business account, a username is a branding tool, not a way to hide the business line. A customer who contacts a business first does not share their number.
The official material we reviewed talks about first-time messages to a person or business, so do not assume ordinary group chats are covered until the Help Center says so.
Availability varies. If you do not see the menu, update the app and check again later rather than installing anything unofficial.

How to set it up, at a high level

Update WhatsApp from your phone's official app store.
Open Settings > Account > Username and reserve a handle. Pick something you would be comfortable giving to a stranger; it does not have to contain your real name.
Decide whether to add a username key. A key makes sense if your username is easy to guess or is printed somewhere public.
Once the feature is live for you, share the username instead of your number when you meet someone new.

Cost: free. Pros: official, no second line needed, works on your existing account. Cons: staged rollout, does not hide a business number, does not undo past exposure. Risks: username look-alikes used by impersonators, so read the context card and verify unusual requests by another route.

Option 2: A second SIM or eSIM dedicated to WhatsApp

A second mobile line that you own is the simplest way to keep your personal number private today. You register WhatsApp on the second number, share only that number, and keep your main number for family, banking and two-factor codes.

Most recent phones support two lines at once, either two physical SIMs or one physical SIM plus an eSIM. WhatsApp's own multiple accounts announcement notes that a second account needs a second phone number and SIM card, or a phone that accepts multi-SIM or eSIM.

How it works

Get a second mobile line in your own name from a licensed carrier, on a plan you intend to keep. A prepaid line is fine if you keep it active.
Install the SIM or activate the eSIM and confirm the line can receive SMS and calls.
Register WhatsApp, or a second WhatsApp account, on that number and complete the SMS or call verification.
Turn on two-step verification and add your email and a passkey straight away.
Set a calendar reminder for whatever the line needs to stay alive: a top-up, a minimum usage rule or a renewal date.

Cost, pros and cons

Cost: the ongoing price of a line, which varies widely by country and carrier. Prepaid numbers usually need some minimum spend or activity to avoid expiring. Check the carrier's terms; we do not quote prices.

Pros: it is a normal mobile number, fully supported by the regular WhatsApp app, and it separates work or selling from private life cleanly. Cons: a second bill to manage, and a second number to protect.

Risks: the main one is letting the line lapse. Carriers recycle numbers. If your second number is reassigned to someone else, that person can receive a registration code for it. See the section on recycled numbers.

What about internet-based (VoIP) numbers?

Be careful here. The WhatsApp Help Center lists VoIP numbers among the unsupported number types for registration, alongside toll-free, paid premium, universal access, shared cost and personal numbers. Landlines are supported only in the WhatsApp Business app. So an app-based number that exists only over the internet may simply fail registration, or may stop working later.

If you want to rely on a number for a business, the safer choice is a mobile number or a true landline that is in your or your company's name, that you can answer when the verification call comes, and that will not expire when a subscription ends.

Option 3: A landline you own, registered in WhatsApp Business

Yes, you can use a landline for WhatsApp, but only in the WhatsApp Business app. The Help Center says landlines are only supported there, and that you receive the code through a phone call to the landline. Customers then see the business line, not anyone's personal mobile.

How to set it up

Install the WhatsApp Business app from the official app store. It can sit on the same phone as your personal WhatsApp.
Enter the landline number in full international format.
When asked how to receive the code, choose Call me. The Help Center explains that when you register through a landline you tap Call me to request a phone call, and an automated voice reads out the six-digit registration code.
Answer the landline, note the code and enter it in the app.
Complete the business profile and turn on two-step verification.

Limits to know

No extensions. The Help Center states that landline extension numbers cannot be used to complete registration. You need a direct number.
You must own the line. The Help Center wording is that you can only register a mobile phone or a landline (fixed) number that you own.

Cost: the app is free; you pay only what the landline already costs. Pros: uses a number customers may already know, keeps staff mobiles private, stable for years if the line is kept. Cons: no SMS, so every re-verification is by call. Risks: closing or moving premises and losing the line without first moving the WhatsApp account to a new number.

Option 4: Two accounts on one phone

WhatsApp officially supports two accounts on one phone, so you do not need a second handset to keep a separate number. There are two official ways to do it.

WhatsApp plus WhatsApp Business

WhatsApp and WhatsApp Business are separate apps and can be installed side by side, each registered to a different number. This is the long-standing route for someone who wants a personal account on their mobile number and a business account on a second mobile number or landline.

The multi-account feature in the main app

WhatsApp announced multiple accounts in its blog post "Multiple Accounts Coming to WhatsApp," first for Android. In March 2026 the Meta newsroom said you can now have two WhatsApp accounts logged in at the same time on iOS, just like on Android, with your profile picture shown in the bottom tab so you can tell which account you are in.

According to WhatsApp's announcement:

You need a second phone number and SIM card, or a phone that accepts multi-SIM or eSIM.
You open WhatsApp settings, tap the arrow next to your name and tap Add account.
Privacy and notification settings are controlled separately for each account.

WhatsApp attaches a warning: only use the official WhatsApp and do not download imitations or fake versions as a way of getting more accounts on your phone.

Cost: the second line only. Pros: one handset, clear separation, official support. Cons: it is easy to reply from the wrong account, so check the profile picture indicator before sending. Risks: the same lapse risk as any second number, plus the temptation to use cloned or modified apps, which you should avoid.

Option 5: Linked devices and companion phones

Linked devices let you use WhatsApp on a computer, tablet or second phone that has no SIM, but they do not give you a new identity. Every linked device uses the same account and the same phone number as your primary phone.

The Help Center says you can use the same WhatsApp account on multiple phones at the same time, using your primary phone to link up to four devices, and that those devices work without the primary phone staying connected. A second phone is linked by choosing "Link as companion device" on the new phone and scanning the QR code with the primary phone, or by entering the primary account's phone number and a one-time code.

Two limits are stated in the Help Center:

Companion phones are logged out if you do not use WhatsApp on your primary phone for more than 14 days.
Re-registering the account with the six-digit code logs out all devices.

The NCSC advises people to regularly check the linked devices list in settings and not to scan unexpected QR codes. Open Settings > Linked devices from time to time and remove anything you do not recognize.

Cost: free. Pros: official, convenient, no extra number. Cons: hides nothing from the people you message. Risks: a linked device left logged in on a shared computer.

Option 6: Channels and Communities

Channels hide your number from other people; ordinary groups do not. If your aim is to follow updates or publish them without exchanging numbers, a Channel is the WhatsApp feature built for that.

Channels

Meta's newsroom explainer on Channels says that following a channel will not reveal your phone number to the admin or other followers, and that who you decide to follow is your choice and is private. It describes Channels as protecting the personal information of both admins and followers. It also notes that admins can block screenshots and forwards, and can decide who can follow and whether the channel appears in the directory.

A Channel is a one-way broadcast, not a place for two-way private conversation. A creator, club or shop that mainly wants to post updates can use a Channel and never hand out a number to followers.

Communities

Communities bring several groups together under one announcement group. The precise visibility rules can change between versions, so read the current Help Center article before relying on a community for privacy.

Two things are clear from the Help Center. Inside an ordinary group, including a group that belongs to a community, members' phone numbers cannot be hidden. And when you leave, your profile name and number are shown in a past members list for up to 60 days.

Cost: free. Pros: strong number privacy for followers of Channels. Cons: not a substitute for private chat. Risks: assuming a community group is as private as a channel. It is not.

Option 7: Click-to-chat links and QR codes

A click-to-chat link or WhatsApp QR code does not hide a number. It packages a number so that people can message it without typing it or saving it. The Help Center explains that click-to-chat lets someone start a chat without having your number saved in their address book, and that the link is built from wa.me followed by the full phone number in international format.

That means the number is inside the link itself. Anyone who receives the link, or scans a QR code that points to it, can read the number and will see it in the chat.

Used properly, these links are still a privacy tool for a business owner, because they make it easy to publish only the business number:

Put the business account's link or QR code on your website, packaging, shop window or invoices.
Never generate a link from your personal account for public use.

Cost: free. Pros: frictionless for customers. Cons: public by design. Risks: scammers also send click-to-chat links; do not open a chat from a link in an unexpected message.

Privacy settings that limit what people see

Privacy settings will not hide your number from someone you are chatting with, but they stop a stranger who has your number from learning anything else and from pulling you into calls and groups. All of them are under Settings > Privacy, and WhatsApp's Privacy Checkup walks you through them.

Setting	What it does	Privacy-first choice
Last seen and online	Controls who sees when you were last active. Options are Everyone, My contacts, My contacts except, or Nobody	My contacts or Nobody
Profile photo	Controls who sees your picture. Same four options	My contacts
About	Controls who sees your about line	My contacts, and keep personal details out of it
Status	Controls who sees your status updates	My contacts, or a selected list
Groups	Controls who can add you to groups. The Help Center notes that by default anyone can add you	My contacts, or My contacts except
Silence unknown callers	Calls from unknown numbers do not ring but appear in your call list	On
Default message timer	Makes new chats start with disappearing messages after 24 hours, 7 days or 90 days. It is off by default	On, at a duration that suits you
Advanced Chat Privacy (per chat or group)	When on, WhatsApp says it blocks others from exporting the chat, auto-downloading media to their phone and using messages for AI features	On for sensitive chats

Notes on the most useful settings

Who can add you to groups. This is the single most effective setting for number privacy, because being added to a group shows your number to every member. Restricting it to contacts means strangers must invite you privately instead, and you can decline.

Silence unknown callers. WhatsApp introduced this in June 2023 to screen out spam, scams and calls from unknown people. Silenced calls still show in the call list in case one turns out to matter.

Advanced Chat Privacy. WhatsApp announced this in April 2025, turned on by tapping the chat name. It restricts exporting, not number visibility.

Changing your number safely

If you want to move WhatsApp off your personal number, use the official Change Number feature rather than deleting the account and starting again. The Help Center says changing your number transfers your account information and settings to the new number, including profile photo, username, display name, privacy settings, contacts, individual chats and group chats.

What happens when you change number

WhatsApp deletes the account associated with your old number, so contacts no longer see the old number in their WhatsApp contact lists.
You choose whether to notify contacts. The options are all contacts, contacts you have chats with, or a custom list.
Group chats are notified automatically whether or not you choose to notify contacts. Every member of your groups will therefore see the new number.
Blocked contacts stay blocked and are not told your new number.
Cloud backups are tied to the number that created them. The Help Center warns that backups made with the old number can no longer be used to restore after the change, so make a fresh backup under the new number.

A safe order of steps

Activate the new line and confirm it receives SMS and calls.
Leave any groups you do not want to carry the new number into, before changing.
In WhatsApp, open Settings > Account > Change number and follow the prompts.
Choose a notification option. "Custom" lets you tell only the people who should have the new number.
Create a new backup and re-check two-step verification, email and passkey.
Only then give up the old line, if you are giving it up at all.

Recycled numbers and numbers that can expire

Phone numbers are reused, so a number you stop paying for will eventually belong to someone else. The WhatsApp Help Center says so directly: since mobile providers recycle numbers, an account you think is your friend's may belong to the new owner of the number.

This creates two risks for anyone using a second or virtual number for WhatsApp.

You lose the account. If a line expires and is reassigned, the new holder can register WhatsApp with it. Your account on that number stops being yours.
Your contacts are confused. People who still have the old number saved may message the new owner, thinking it is you.

Before you give up any number

Move the account with Change Number, or delete the account from Settings > Account if you no longer want it. Either step removes the account from the old number.
Tell close contacts to delete the old number. The Help Center recommends removing someone's old number from your address book when they switch.
Remove the old number from other services that use it for sign-in codes.

How two-step verification, email and passkeys reduce the risk

WhatsApp's extra account protections make it harder for someone who gets hold of a number to walk into the account:

Two-step verification PIN. A PIN you set, which is requested in addition to the SMS or call code when the number is registered again.
Email address. The Help Center says an email on the account lets you reset a forgotten PIN and, when re-registering your number, receive a code by email.
Passkey. The Help Center describes a passkey as using your device's fingerprint, face or screen lock, so that you can verify your identity with it instead of an SMS code when registering your number or restoring your account.

For mobile numbers there is also the risk of someone moving your number away from you. The FCC describes port-out fraud as a scammer transferring your number to another provider, and its advice includes adding a PIN or password to your carrier account. A phone that suddenly loses service is a warning sign.

Verification codes and account takeover

The six-digit registration code is the key to a WhatsApp account, so it must never be shared and must only ever arrive on a line that is yours. WhatsApp's Help Center says you should never share your registration code with others, not even friends or family.

The common takeover scam is simple. UK Action Fraud describes it: a criminal who has already taken over a friend's account messages you from it, a WhatsApp code arrives on your phone, and the "friend" says they sent it to you by accident and asks you to pass it on. If you do, you are locked out. The FTC's advice is the same: the code is only for you, and anyone who asks for it is a scammer.

This is also why shared or public numbers are unsafe for WhatsApp. If other people can read messages sent to a number, any of them can end up in control of the account, which is a risk to your contacts as well as to you.

Warning signs and what to do

A code you did not request. Ignore it and do not forward it. The Help Center notes that unrequested emails to reset your PIN or registration code can mean someone is trying to access your number on WhatsApp, and tells you not to click the links.
A message saying your number was registered on a new device. Follow the on-screen recovery steps. Re-registering with the code logs out all other devices.
An unusual request for money or a code from a friend. The NCSC and Action Fraud advise calling the person to confirm.

Account takeovers are often the first step in payment fraud. Our guides on how to avoid loan scams and fake offers and how to spot a crypto scam cover what those follow-up messages tend to look like.

What WhatsApp collects, and your data rights

WhatsApp collects your phone number, your profile information, the phone numbers in your address book if you allow contact upload, and technical information about your device and connection. This is set out in its Privacy Policy. Message content is a separate matter and is protected by end-to-end encryption.

Type of information	What the Privacy Policy says	What you can do
Account information	You must provide your mobile phone number and a profile name to create an account	Register a number you are comfortable using; keep the profile minimal
Contacts	If permitted, WhatsApp receives the phone numbers in your address book on a regular basis, including those of people who do not use WhatsApp	Contact access is a phone permission you can decline or limit; some features work less smoothly without it
Usage information	How you use the service, settings, registration date, online status and last seen	Limit last seen and online visibility to others
Device and connection information	Hardware model, operating system, app version, phone number, mobile operator or ISP, IP address and identifiers	Keep the app and phone updated

A second number or username changes what other users see; it does not make you anonymous to WhatsApp, which still holds the number you registered.

Your rights in brief

WhatsApp's Privacy Policy says you can access, manage and delete your information through in-app settings, and delete your account at any time. In the app, Settings > Account includes a tool to request a report of your account information.

If you are in the UK, data protection law gives you formal rights. The ICO explains that you have the right to ask an organization for a copy of your personal information, known as a subject access request, that organizations usually have one month to respond, and that in most circumstances the copy should be free. Readers elsewhere should check their own national or state privacy law.

Advice for specific users

The right setup depends on who you are hiding the number from. The table gives a starting point for each group, and the notes below add detail.

You are	Main concern	Sensible setup
Freelancer or small business	Clients having your private mobile	WhatsApp Business on a dedicated mobile line or landline; business username when available
Online seller	Strangers from listings; scam attempts	Second number or business account; silence unknown callers; never share codes
Dating	Handing a number to someone you have just met	Username with a key when available; restrict profile photo and last seen
Journalist or activist	Targeted takeover or surveillance	All account protections on; follow official high-risk guidance; consider a different tool for sources
Parent of a teen	Strangers contacting or adding the child	Groups limited to contacts; profile to contacts; talk about codes and links

Freelancers and small businesses

Keep client contact on a business account from day one, so you can hand the number to a colleague or close it without touching your private life. A landline registered in the Business app suits a fixed premises; a dedicated mobile line suits someone on the move. Our guides on getting paid as a freelancer by international clients and writing a business plan cover the wider admin.

Online sellers

A number on a public listing will be harvested. Use a second number or business account, keep your profile photo to contacts, and be alert to buyers who ask you to read back a code "to prove you are real." Sellers who take card payments may also find our guide to card-not-present fraud prevention for small merchants useful.

People who are dating

Until you trust someone, stay on the dating platform's own chat, or share a WhatsApp username once the feature is live for you. If you do share a number, set profile photo, about and last seen to contacts so that an unsaved number sees very little.

Journalists, activists and other high-risk users

If you could be specifically targeted, settings are only part of the answer. The NCSC has warned about targeting of messaging apps; its advice includes not sharing verification codes, not scanning unexpected QR codes, enabling two-step verification and checking linked devices. Follow the guidance of your national cyber security agency and your organization's security lead. For contacts who must not learn your number at all, consider whether a number-based messenger is the right tool.

Parents and teens

WhatsApp's Terms set a minimum age of 13, or higher where a country requires it. For a teen's account, the most protective steps are restricting who can add them to groups, limiting profile photo and last seen to contacts, turning on silence unknown callers, and setting a two-step verification PIN with a parent's email as backup. Talk about never sharing a code.

Alternatives if you need no phone number exposure at all

If your requirement is that the other person must never be able to learn any phone number of yours, look at the type of service rather than a workaround. We describe categories only and do not rank products.

Username-based messengers. Some messaging services let people find you by a handle and never display a number to other users, even if a number is used at sign-up. WhatsApp's username feature moves it toward this model.
Platform inboxes. Marketplaces, dating apps and freelance platforms have built-in chat. Staying inside it keeps your number private and often keeps you within the platform's dispute and safety systems.
Email or a web contact form. For a business, a contact form or a dedicated mailbox is still the lowest-exposure first point of contact.

What not to do

Avoid any method that relies on a number you do not own, an unofficial app, or creating accounts to get around WhatsApp's rules. These are the practices that most often end in a lost account or a locked-out user.

Risky practice	Why it is a problem	Do this instead
Registering with a shared, public or throwaway number that receives texts for many people	Anyone who can see that number's messages can request a code and take the account. It also breaks the rule that you register a number you own	A second SIM or eSIM in your name
Registering with a friend's or relative's number	They, not you, control re-verification. A dispute or a lost phone ends your access	Your own line
Using modified or imitation WhatsApp apps for extra accounts	WhatsApp says your messages are only secure and private in the official app	The official multi-account feature or the Business app
Sharing your six-digit code or PIN	It hands over the account. WhatsApp and the FTC both say never to share it	Ignore the request and report the chat
Letting a WhatsApp line expire	Carriers recycle numbers; the next holder can register it	Keep the line active, or use Change Number first
Opening a new account to get around a ban	It does not resolve the reason for the ban and can lead to further action	Use the in-app review request
Posting a click-to-chat link made from your personal account	The link contains your number	Publish only a business number or username

Step-by-step privacy checklist

Work through this list once, in order. It takes about fifteen minutes and covers both hiding the number and protecting the account behind it.

Update WhatsApp from the official app store so that current privacy features appear.
Decide which number faces the public. If it should not be your personal mobile, set up a second line or a business account before you share anything further.
Reserve a username under Settings > Account > Username if the option is available, and consider a username key.
Turn on two-step verification and choose a PIN you do not use elsewhere.
Add your email address to the account for PIN reset and re-registration codes.
Create a passkey if your device offers it.
Run Privacy Checkup in Settings > Privacy.
Set Groups to My contacts so strangers cannot add you.
Set Profile photo, About, Last seen and online, and Status to My contacts or tighter.
Turn on Silence unknown callers.
Set a default message timer if disappearing messages suit you, and turn on Advanced Chat Privacy in sensitive chats.
Review Linked devices and log out anything you do not recognize.
Protect the line itself. Add a PIN or password to your carrier account and ask about a port-out or SIM lock.
Before dropping a number, use Change Number or delete the account.

No. WhatsApp's Privacy Policy says you must provide a mobile phone number to create an account, and its usernames FAQ confirms you still need a phone number to register and use WhatsApp. You can avoid exposing your personal number by using a username, a second number you own, or a business account on a separate line.

Can I hide my number on WhatsApp?

Partly. In ordinary chats and groups the Help Center says the number cannot be hidden. With usernames, WhatsApp says a person or business you message for the first time will no longer see your number if you have enabled a username. Channels do not reveal followers' numbers. Privacy settings hide your photo, about and last seen but not the number itself.

Is the WhatsApp username feature available now?

WhatsApp opened username reservations in mid-2026 and said the full feature would roll out gradually over the following months, by country. Check Settings > Account > Username on the latest version of the app to see what your account has.

What is a WhatsApp username key?

It is an optional extra code that others must know, along with your exact username, to message you for the first time. WhatsApp says you can reset it at any time to stop new contacts reaching you through your username. It is not the same as your two-step verification PIN, which protects the account itself.

Can I use a landline for WhatsApp?

Yes, in the WhatsApp Business app only. Choose Call me during registration and an automated call reads out the code. The landline must be one you own and cannot be an extension.

Can I use a VoIP or virtual number for WhatsApp?

The Help Center lists VoIP numbers as unsupported for registration, along with toll-free and premium numbers. A mobile number or true landline that you own is the reliable choice.

Can I have two WhatsApp accounts on one phone?

Yes. WhatsApp's official multi-account feature lets you add a second account from settings, and Meta said in March 2026 that this works on iOS as it does on Android. You need a second number. You can also run WhatsApp and WhatsApp Business side by side on different numbers.

Does WhatsApp Web or a linked tablet need its own number?

No. Linked devices use your existing account and number. You can link up to four, and companion phones are logged out if the primary phone does not use WhatsApp for more than 14 days.

Can people in a WhatsApp group see my number?

Yes. The Help Center says it is not currently possible to hide group members' numbers in a group. Limit who can add you to groups, and note that your name and number stay in a past members list for up to 60 days after you leave.

What happens to my WhatsApp if my number is given to someone else?

The new holder can register WhatsApp on that number, and you lose the account. Before giving up a number, move the account with Change Number or delete it. Two-step verification, an email address and a passkey make an unwanted takeover harder but do not replace keeping the line.

Will my contacts know if I change my WhatsApp number?

Only those you choose to notify, with one exception: group chats are notified automatically. Blocked contacts are not told.

Is it safe to register WhatsApp with a number from a free online SMS website?

No. Those numbers are shared and public, so anyone can read the code and take over the account, and it is not a number you own as WhatsApp requires. Use a line in your own name.

Someone asked me for a WhatsApp code that arrived on my phone. What should I do?

Do not send it. WhatsApp says never to share your registration code, even with friends or family, and the FTC says anyone who asks for a verification code is a scammer. Call the person on a known number to check whether their account has been taken over.

Bottom line

WhatsApp is built on phone numbers, and no legitimate method removes the need for one. The realistic goal is to stop your personal mobile number spreading further than you want. Reserve a username and use it as the feature reaches you. If you deal with customers or strangers, put a second line or a business number between them and your private life.

Then protect the account behind the number: two-step verification, a recovery email, a passkey, a carrier account PIN, and a firm rule that codes are never shared. Use only numbers you own and intend to keep, and move or delete the account before you ever let a number go.
