Migrating a Phone Number

WhatsApp offer two types of products for business:

  • The SMB app
  • The WhatsApp Business API

In this Quickstart, you'll learn how to migrate your phone number from the WhatsAPP SMB app in 5 simple steps, so that it can be used in the WhatsApp Business API instead.

Before we go ahead, is the phone number already being used with the WhatsApp Business API?

  • Yes! You have to pick a different phone number because it cannot be migrated.
  • No! Great! Go ahead with the Quickstart.

You can use a phone number that's already registered in the Android, iOS, or Business Application versions of WhatsApp; however, if you add that phone number to your Business Manager, you'll see a Phone Number is Invalid error. Don't worry, simply follow the 5 easy step of this Quickstart to delete the WhatsApp account associated with that phone number. Keep in mind that any incoming messages during this time will be queued by the WhatsApp servers and delivered once the registration is successful.

Step 1

Open the WhatsApp or WhatsApp Business app on your Android or iOS.
