Instagram or Facebook Confirmation Code Not Received? How to Fix It
If your Instagram or Facebook confirmation code doesn't arrive, the number may be in the wrong format, unable to receive SMS, or you've requested codes too quickly. Enter the number in full international format on a real mobile that can receive SMS, wait for the timer, request the code again, or use the email option if available.
How the code is sent
Instagram and Facebook confirm a mobile number by sending a verification code by SMS; the number is kept private and used for login help, notifications and SMS two-factor authentication.
If SMS doesn't arrive, both usually offer an email confirmation option or let you request the code again after a short wait.
Common causes
The number is in the wrong format, or is a type that can't receive the SMS code.
Too many code requests in a short time, triggering a temporary wait.
Carrier or network delay on the SMS, or no signal/data on the device.
How to fix it
1. Re-enter the number in full international format (+ country code, no leading 0).
2. Use a real mobile number that can receive SMS, and make sure it has signal.
3. Wait for the countdown, then tap “Resend code”.
4. If offered, confirm by email instead of SMS.
5. Avoid rapid repeated attempts, which can delay delivery further.
