The Change Number feature allows you to change the phone number associated with your WhatsApp account on your same phone. This feature is intended to be used before you verify your new number.
Using the Change Number feature in WhatsApp will:
Migrate your account information (including your profile information), groups and settings from your old phone number to your new phone number; and
Delete the account associated with your old phone number, so your contacts can no longer see your old phone number in their lists of WhatsApp contacts.
If you use our Change Number feature, your chat history will continue to be available on your phone with the new phone number as long as you continue using the same phone.
Please make sure your WhatsApp contacts have your new phone number saved in their phone’s address books to ensure a seamless messaging experience.
Before beginning the Change Number process
Make sure your _new phone number_ can receive SMS or calls and has an active data connection.
Make sure your _old phone number_ is currently verified in WhatsApp on your phone. You can see what number is verified in WhatsApp by navigating to WhatsApp > More options > Settings and tapping on your profile photo.
Note: When you change your WhatsApp phone number, your contacts won't individually be informed of the change. Only participants that share group chats with you will see that you changed your number. For a seamless messaging experience, notify your contacts that your number will be changing before you begin this process.
