Registering business phone numbers

Updated: Nov 14, 2025
This document describes the steps to programmatically register business phone numbers on WhatsApp Business Accounts (WABA).
Note that Embedded Signup performs steps 1-3 automatically (unless you are bypassing the phone number addition screen) so you only need to perform step 4 when a business customer completes the flow. If you have disabled phone number selection, however, you must perform all 4 steps.
Registering business phone numbers is a four step process:
    Create the number on a WABA.Get a verification code for that number.Use the code to verify the number.Register the verified number for API use.
    These steps are described below.
    You can also perform all 4 steps repeatedly to register business phone numbers in bulk.
