Add Phone Number to WABA
Add, verify, and manage a WhatsApp Business Account phone number in a Workspace.
Add and verify a phone number (sender) for an existing WhatsApp Business Account (WABA) in Communications Platform so the Workspace can send WhatsApp messages.
A WhatsApp Business Account (WABA) is a Meta account that manages your business profile and WhatsApp senders. Each phone number must be linked to one WABA, assigned to a Workspace, and verified before you can use it for WhatsApp messaging.
WARNINGA phone number can be active in only one Workspace at a time. If the phone number is already active in another Workspace, you cannot reuse it.
Confirm the WABA creation method
Confirm how the WABA was created before you add a phone number. The creation method determines how you can add and verify phone numbers.
| Method | Description | Phone number limits |
|---|---|---|
| Partner-Initiated Process | Messangi sends the customer an invitation by email or support ticket. The customer reviews and accepts the invitation, optionally adds a phone number (sender), and confirms. After the customer accepts, the WABA is created under the customer's Meta Business account and shared with Messangi. | After the WABA is active, you can add and verify phone numbers directly in the platform by using WABA Phone Numbers. After Meta verifies the WABA, you can add up to 25 phone numbers. |
| Embedded Sign-Up | The customer creates or links their own WABA through the Embedded Sign-Up flow in the platform. They authenticate with Meta and complete the setup, including the phone number and business profile information. The WABA is created under their Meta Business account. | Add phone numbers during the sign-up process. To add more numbers later, repeat the Embedded Sign-Up flow. If the WABA is not verified, you can add up to 2 phone numbers during Embedded Sign-Up. After Meta verifies the WABA, you can add up to 25 phone numbers. |
