Manage Phone Numbers and Certificates

This guide provides overview information relating to phone numbers for Solution Partners and customers. Additionally, this guide contains process information for Solution Partners in the case that they have to manage a customer's phone number and certificates.

Preliminary information about Phone Numbers

There are some details that businesses need to know surrounding phone numbers and Embedded Signup.

Businesses need a dedicated number to use WhatsApp through embedded signup. If a business has a number actively registered on WhatsApp Messenger or the WhatsApp Business App, they are not able to use the same phone number.

Businesses can have multiple phone numbers associated with their Meta Business Account, so all they have to do is add another phone number and use that for WhatsApp.

A business cannot sign up using the embedded signup flow with a phone number that has already been registered with the Business or consumer application versions of WhatsApp.

For more detailed information relating to phone numbers and WhatsApp for Business Platform, see Phone Numbers.

For information on how to migrate an existing registered WhatsApp phone number, see Migrate Phone Number.

Instructions for customers

This section is directed towards customers of Embedded Signup and provides guidance about actions they may perform relating to phone numbers.

Add Phone Numbers to a WhatsApp Business Account

There are two methods to add additional numbers to a WhatsApp Business Account (WABA):

  1. [Recommended] Go through the embedded signup flow again, select the existing Business Manager & WABA, add the number, and verify it.
  2. In the Business Manager, go to the Phone Numbers tab of WhatsApp Manager, and select Add Phone Number. When using this option, the Solution Partner has to manually verify the phone number as phone verification is not available in the Business Manager. For this reason, it is recommended that businesses follow the embedded signup flow to add additional numbers.

Instructions for Solution Partners

Register Phone Numbers for Cloud API

After a successful phone verification from the embedded signup flow, registration should succeed with an API call to the register endpoint. For this, provide any code_method (sms | voice). Since the phone number is already verified, you do not need to worry about the registration code. The verify API call is not required.

Alternatively, you can pre-verify phone numbers and offer them to your customers in the new Embedded Signup flow. This prevents customers from having to contact you for a one-time password during the onboarding process. See Pre-Verified Phone Numbers.

Register Phone Numbers for On-Premises

After a successful phone verification from the embedded signup flow, registration should succeed with an API call to the account endpoint. For this, provide any code_method (sms | voice). Since the phone number is already verified, you do not need to worry about the registration code. The verify API call is not required.

Alternatively, you can pre-verify phone numbers and offer them to your customers in the new Embedded Signup flow. This prevents customers from having to contact you for a one-time password during the onboarding process. See Pre-Verified Phone Numbers.

A phone number must be registered up to 14 days after going through the Embedded Signup flow. If a number is not registered during that window, the phone must go through to the Embedded Signup flow again prior to registration.

The phone_numbers endpoint allows you to see the status of a phone number's display name and to retrieve the certificate after a name change. See the Read Phone Numbers for more information.
