Add Phone Number to WABA

When managing a WhatsApp Business Account (WABA), you may need to associate one or more phone numbers (senders) so your business can communicate with customers via WhatsApp. Each phone number must be linked to a specific WABA and properly verified and assigned before it can be used within a space.

This section explains how to add a new phone number to an existing WABA from within the Digital Engagement Platform.

🚧

WARNING

• If the phone number is already in use in another space, it cannot be reused. A phone number can only be active in one space at a time.

• To add and verify phone numbers directly within the platform depends on which method your WhatsApp Business Account (WABA) was created:

  
  

  Method	Description	Adding Phone Number Limitations
  Partner-Initiated Process	The WhatsApp Business Account (WABA) is created after the customer receives an invitation sent by the Messangi team via email or support ticket. The customer review and accept the invitation, optionally add a phone number (sender), and confirm. Once accepted, the WABA is created under the Meta Business account of the customer and shared with Messangi.	Phone numbers can be added and verified directly within the platform using the WABA Phone Numbers feature, once the WABA is active.
  Embedded Sign-Up	This self-service method allows the customer to create or link their own WhatsApp Business Account (WABA) through the Embedded Sign-Up flow available in the platform. They must authenticate with Meta and complete the entire setup, including assigning a phone number and business profile information. The WABA is created under their Meta Business account.	Phone numbers must be added as part of the sign-up process. To add more numbers later, the client must repeat the Embedded Sign-Up flow.
