Verification Codes on iPhone: Where They Appear and Fixes

On iPhone, text verification codes appear in Messages and are suggested above the keyboard so you can fill them in with one tap. If a code is missing, it is usually filtered, blocked or sent somewhere else.

Where the code shows up

• In Messages, sometimes under the filter for unknown senders.
• Above the keyboard, as an AutoFill suggestion, in the app asking for it.
• In email, if the service sends codes there.
• In the Passwords app, for codes from accounts you saved with verification codes.

Code not arriving on iPhone: fixes

1. Open Messages and check the unknown senders and spam lists.
2. Make sure the sender is not blocked (Settings › Apps › Messages › Blocked Contacts, or Phone › Blocked).
3. Turn off Focus or Do Not Disturb while you wait.
4. If the code is from an iMessage contact, check that Send as SMS is on.
5. Toggle airplane mode or restart to reconnect to the network.
6. Check that short-code texts are not blocked by your carrier.

Apple ID codes are different

Apple Account codes appear on your other signed-in Apple devices first, and only then by text. See Apple ID two-factor.

Clean up codes automatically

Recent iOS versions can delete verification codes from Messages and Mail after you use them; look for the option under Passwords › Password Options. It keeps old codes out of your inbox.

Codes while travelling

Texts from short codes may not reach you when roaming. Switch the app to email or an authenticator before you travel, or turn on roaming for a minute to receive the code.
