Steps to use phone number that has been registered with Whatsapp Business before.

To apply for WhatsApp API verification, you must use a number that does not have an account on any WhatsApp apps.

You can use a phone number that is already registered in the Android, iPhone, or Business application versions of WhatsApp.

However, to register this phone number on the WhatsApp Business API, you will need to follow the steps below to delete the WhatsApp account associated with that phone number.
