Common Issues:

If the binding fails, you can determine the cause of the error based on the prompt, which may include:
  1. The maximum number of bindable numbers has been reached. Unverified businesses can only bind up to 2 phone numbers. If you need to bind more, please complete the business verification.
  2. The number has already been registered with WhatsApp.
    1. This number may already be registered with the WhatsApp app or WhatsApp Business app. It is recommended to change the number or unregister it within the app. Note: Chat history will not be transferred after unregistration.
    2. WhatsApp Business API account. It is recommended to migrate this number rather than adding it anew.
Try using a voice call to receive the verification code. If you still cannot receive it, it is recommended to change to a new number.
