How to Change Your WhatsApp Phone Number Without Losing Chats

You can change your WhatsApp phone number without starting over. Use the built-in Change number feature to move your account to a new number while keeping your existing groups, settings, and chats on the same phone. You will need to verify the new number. If you are also switching phones, the order of operations matters.

Before you change your WhatsApp number

Make these checks before you begin:

• Confirm your current number: Open WhatsApp Settings and tap your profile to see the number registered to your account.
• Activate your new number: It must be able to receive verification texts or phone calls. WhatsApp does not accept every number type, including many VoIP and toll-free numbers.
• Use your primary phone: You cannot change the number from WhatsApp Web, Desktop, or a linked companion device.
• Tell important contacts: Ask people who need to reach you to save the new number. This is particularly important for broadcast-list recipients.

If your phone is being replaced too, keep the old phone and its chats available until the migration is complete. Do not erase the old device prematurely.

How to change your WhatsApp phone number on the same phone

1. Open WhatsApp Settings. On Android, open the three-dot menu and select Settings. On iPhone, tap the Settings tab or your profile, depending on your app layout.

   

   

   

2. Go to Account > Change number. This is the option for transferring an existing account, not creating a second account.

   

3. Tap Next. Read the explanation about moving your account information, groups, and settings.

   

4. Enter both numbers. Type the currently registered number in Old phone number and the replacement in New phone number. Use the full international format, including the correct country code, and double-check each entry before tapping Next.

   

   

5. Choose whether to notify contacts. Turn on Notify contacts if you want WhatsApp to inform everyone in your contacts, only contacts you have chats with, or selected people. If you leave it off, your group chats are still notified automatically.

   

6. Finish and verify the new number. Tap Done and follow the registration prompts. Enter the verification code you receive on the new number, or use an available verification method shown by WhatsApp. Never share a verification code with another person.

These instructions follow WhatsApp's official Change number guide. Menu placement can vary slightly between Android, iOS, and app versions.

What happens to chats, groups, and contacts?

When you change numbers using this feature, WhatsApp transfers your account information to the new number, including your profile, privacy settings, individual and group chats, and group membership. On the same phone, your existing chat history remains available. The WhatsApp account attached to the old number is removed.

Group chats receive an automatic notice. For other contacts, the notification depends on the choice you made during setup. People may still need to save your new number in their phone's address book. Contacts you have blocked remain blocked and are not notified of the number change.

Changing your number does not make an old cloud backup valid for the new number. WhatsApp ties backups to the phone number used when they were created, so create a fresh backup after the change if you rely on cloud recovery. See WhatsApp's explanation of what changes with your number.

Changing your number and your phone at the same time

Do not install WhatsApp on your new phone and register the replacement number first if you need your old chats. Instead, change the account number on your old phone first. Next, create a backup associated with the new number or use WhatsApp's supported chat-transfer method for your device combination. Then install WhatsApp on the new phone, register the new number, and restore or transfer chats as instructed.

Cloud-backup services and transfer options differ between Android and iPhone, especially when moving between operating systems. Check WhatsApp's official changing-phones instructions before wiping or trading in the old device.

If Change number is missing or isn't working

• Option is grayed out: You may be using a linked device rather than the primary phone.
• Old number is rejected: Check the currently registered number in your WhatsApp profile and enter that number, not merely the number on your current SIM.
• New number won't verify: Check the country code, cellular service, and whether the number can receive calls or texts. If you recently requested several codes, follow the wait time shown in the app rather than retrying rapidly.
• New number was used before: Phone numbers can be reassigned by carriers. Follow WhatsApp's registration flow; a previous owner's account does not automatically give them access to your chats.

For additional checks, use the official WhatsApp troubleshooting guide. The safest sequence is to change your number on your primary phone, verify it, make a new backup, and only then move devices if necessary.
