Security code not arriving

The code is going somewhere else, or it's being blocked.

Fix it in order

1. Check spam, promotions and "all mail" for messages from Meta's real domains.
2. Make sure you're entering the exact email or number on the account.
3. Wait a few minutes between requests. Repeated requests get rate-limited.
4. For SMS, check signal, roaming and any carrier spam filter. Try switching to an email code.
5. On WhatsApp codes, check the number's WhatsApp is active.
6. If the contact details aren't yours any more, it's a hack. Follow the recovery checklist.

If your number changed

Choose the option that says you can't access this phone number, then use email, selfie or ID.

Questions people ask

Why does Instagram say 'please wait a few minutes before you try again'?

Too many code requests triggered a temporary limit. Wait, then request once.

Can a hacker block my codes?

If they changed the email or phone, the codes go to them. That's a hack, not a delivery problem.
