Why the Verification Code May Not Arrive
Carriers may delay SMS, your number may be mistyped, or WhatsApp may throttle repeated requests. Unsupported clients can also trigger official-app messages instead of completing setup.
Check These Things First
Confirm Your Phone Number and Country Code
Re-enter the number without leading zeros your country does not use internationally.
Check SMS Reception and Call Availability
Verify you can receive normal texts and voice calls. Try “Call me” if offered.
Review Any Countdown or Retry Message
Wait for the timer before requesting another code to avoid throttling.
What to Do If the Code Still Does Not Arrive
Restart the phone, disable airplane mode, and confirm no SMS blocking apps interfere. If problems persist on Wi‑Fi only, test mobile data.
What If WhatsApp Says to Use the Official App?
That is an account/client issue, not SMS delivery. See GB WhatsApp says use official WhatsApp rather than requesting endless codes.
How to Protect Your Verification Code
Never share codes with strangers or “verification services.” WhatsApp will never ask for your code by chat.
