Migrate an Existing WhatsApp Number to a Business Account

You can use a phone number that is already registered with the WhatsApp Messenger or the WhatsApp Business App. Remember to back up your chat history from the WhatsApp Business App.

Once you migrate a phone number to the WhatsApp Business Platform, you cannot use that number on the WhatsApp Business App concurrently. Your number must be used either on the Business Platform or on the Business App.

To migrate a number, you must first delete that WhatsApp account.

  1. In Business Manager, add the phone number that is already registered with WhatsApp Messenger or WhatsApp Business App.
  2. Assign a display name to your phone number, following the display name guidelines. Submit it for review by the WhatsApp team. You will be notified when the display name is approved. You won't be able to download a certificate if your WhatsApp account on your Android or iPhone is still active.
  3. Open WhatsApp Messenger or WhatsApp Business app on your Android or iPhone.
  4. Navigate to Settings > Account.
  5. Select Delete my account. Messages sent to this phone number will be queued in the meantime.
  6. Follow the steps to delete the WhatsApp account for that phone number. It may take up to 3 minutes for the disconnected number to become available.

Once the number is available, return to Business Manager and refresh your browser window. You can now download a certificate and proceed with the registration process. After registration, the queued messages that were sent when you deleted your WhatsApp account will be released with no rate limit and delivered to your phone.
