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 use with Cloud API or On-Premises API. These steps are described below. You can also perform all 4 steps repeatedly to register business phone numbers in bulk.
