Outlook Verification Code Not Received? 8 Fixes That Work

Outlook or Microsoft code not arriving? Try another verification option or the Authenticator app, check your security info, and wait out limits. 8 fixes.

Outlook.com, Hotmail and every other Microsoft service use one Microsoft account, so the same security codes protect all of them. Codes come by text, email or the Microsoft Authenticator app, and a locked account asks for a text code to unlock. Here is what to check when the code doesn't arrive.

Check these first (30 seconds)

• Authenticator app. If Microsoft Authenticator is set up, approve the sign-in or read the code there.
• Your security info. Codes only go to the phone numbers and emails saved as security info on the account.
• Use a different verification option. The code screen lists every method Microsoft has for you.
• Spam and filtered texts. Check spam folders on your phone and in your alternate email.

What Microsoft's message means

8 fixes, in order

1. Use Microsoft Authenticator. Approve the sign-in in the app, or use the one-time code it shows.
2. Pick a different verification option. Switch between text, alternate email and Authenticator on the code screen.
3. Resend once. Wait, then request one new code. Only the newest works.
4. Turn off SMS filters and restart. Pause spam filters and blockers, and check signal or roaming.
5. Check the number format. Choose the country from the list, then type the number without a leading 0.
6. Unlock a locked account by text. Follow the "Your account has been locked" screen; it needs any mobile number that can receive a text, not necessarily your security info number.
7. Use the recovery form. If you have no working method, choose "I don't have any of these" and complete the account recovery form from a device you used before.
8. Wait out a limit. After "too many codes", wait several hours; retrying makes it longer.

Security info changes take 30 days

When you replace all your security info, Microsoft waits 30 days before the change takes effect, so a thief who changes it can't lock you out at once. During that time codes may still go to the old phone or email. Plan ahead: add the new number while the old one still works.

Manage it at account.microsoft.com → Security → Advanced security options. Add at least two methods (a phone and an alternate email), or go passwordless with Authenticator.

When your own number just won't work

Microsoft refuses some internet-based (VoIP) numbers, and a number used too often for codes can be paused.

In that case a non-VoIP number is the practical fix. These are real mobile-carrier numbers, which is what Outlook expects. On SMS Pin Verify you can pick a USA number for Outlook and the code appears on screen in your account:

• One-time number: held for you for 15 minutes to receive one code. If no code arrives, you are not charged. Good for a single sign-up.
• Rental number: the same number for several days or longer. Pick this if the number will be part of your security info, because Microsoft texts it again for new devices and unlocks.

Two honest limits: a code is never guaranteed, because Outlook decides whether to send it; and a number may have been used on Outlook before you, so start a fresh account rather than trying to recover an old one.

Keep your account after you get in

• Add two or more security methods and keep them current.
• Use Microsoft Authenticator or a passkey so you don't depend on texts.
• Save your recovery code (Security → Advanced security options) somewhere offline.
• Never share a Microsoft code. Microsoft support will not ask for it. Tech-support pop-ups asking you to call are scams.

FAQ

Why is Microsoft not sending my security code?

Old security info, filtered texts, or too many requests. Choose a different verification option or use Authenticator.

How do I unlock my Outlook account without the old number?

The unlock screen accepts any mobile number that can receive a text. Enter one and use the code.

Why does changing my security info take 30 days?

It is a protection: if someone else changes it, you have time to stop them.

Do virtual numbers work for Outlook?

Free and VoIP numbers often don't. Non-VoIP mobile numbers work much more often.
