# Request a phone number verification code

> Asks WhatsApp to send a one-time verification code to the phone number via SMS or voice call. The code is delivered to the underlying phone line, not to the API caller; follow up with verify-code once the user receives it. Step 1 of the phone-number registration flow (request-code, verify-code, register).
