  • Your WhatsApp profile, settings, and groups will be moved over to your new phone number.
  • You won't be able to access your WhatsApp account on your old phone.
  • The account associated with your old phone number will be deleted, so your contacts through the app won't see it listed in their contacts list.


Because of all these consequences, it's a good idea to give your WhatsApp contacts a heads up about your new phone number. That way, they won't accidentally lose touch with you when you make the change.

6. Hit Back Up.

If you still have access to your old phone, you'll need to go through the steps above to change your number on your old phone. Or, if you still have your old phone, you can simply delete your account associated with that number on that phone.

Then, follow the steps below to set up WhatsApp on your new phone.

1. Install WhatsApp on your new phone.

2. Register the new phone number you want to be associated with your WhatsApp account.

3. Restore your account backup.

Quick tip: If you no longer have access to your old phone and can't change your number or delete your account, all your account data associated with the old phone and phone number will be deleted if the new owner of your old phone activates WhatsApp after 45 days. You'll also need to set up an entirely new WhatsApp account.
