Add Phone Number to WABA

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. Before you can send WhatsApp messages, link each phone number to one WABA, assign it to a Workspace, and verify it.

⚠️
WARNING
A 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.

Identify the WABA creation method

Identify how the WABA was created before adding a phone number. Its creation method determines how you add and verify phone numbers.

Method	Description	Phone number limits
Partner-Initiated Process	The customer’s Business Solution Provider (BSP) sends 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 the BSP.	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.

Go to Preferences > Channel management, locate the row where Type is WhatsApp WABA, and click the Edit icon.

The WhatsApp Business Account view opens and lists the phone numbers for the WABA.

After verification, wait 60 to 120 minutes for the phone number to become active and ready for WhatsApp messaging in this Workspace.

Edit the display name

The WhatsApp Business Display Name is the business name customers see on your WhatsApp Business Profile. Meta uses the display name to create the certificate required to register the account on the WhatsApp Business platform.

Use a name related to your business that complies with the WhatsApp Business Message Policy. After the phone number is verified and active, update its display name from the Phone Numbers table:

Locate the sender you want to update and click the edit (pencil) icon next to its current Display Name.

Enter the new display name.

The New Display Name window shows the name currently associated with the phone number.

Field	Description
Name	Shows the name currently assigned to the phone number. Use it to confirm that you are editing the correct sender.
New Display Name	Enter the name customers see in WhatsApp conversations and on your business profile. It must contain 3 to 80 characters. Use your legal business name, brand name, or a product name that clearly identifies your company. Avoid generic or misleading terms, such as “Customer Support” or “Official Account”.

Click Save to submit the change for review by Meta.

The new display name appears after Meta completes the review, which may take 60 to 120 minutes. If Meta rejects the change, the previous display name remains active.
