The user is unable to receive Microsoft verification codes via text message (SMS) and needs a way to successfully authenticate or recover their account.

How to Fix Microsoft Verification Codes Not Arriving by Text Message

Product: Microsoft Account
Device & OS: not provided
Scenario: Attempting to sign in or verify identity for a Microsoft account but failing due to missing SMS verification codes.
Observed behavior: Verification texts fail to arrive, potentially going to an incorrect phone number, being blocked by carrier filtering, or experiencing account-security delivery delays.

Before you start

Before proceeding, check if your phone has a strong cellular signal and ensure you haven't accidentally blocked messages from unknown numbers. Avoid requesting the code multiple times in a row, as this can trigger a temporary security block on your account.

Solution 1Recommended

Use an Alternative Verification Method

Use this solution if you have previously set up other authentication methods, such as an alternate email or the Microsoft Authenticator app.

Microsoft allows you to bypass the text message verification if you have alternative security information tied to your account. This is the fastest way to regain access without waiting for carrier issues to resolve.

Select an alternate method

On the sign-in page where you are prompted for a code, click on the option that says 'Sign in another way' or select a different available verification method from the list.

Choose email or Authenticator

Select your alternate email address or the Microsoft Authenticator app to receive the prompt or code.

Enter the new code

Retrieve the code from your email or approve the sign-in via the Authenticator app to access your account.

Tip: Using the Microsoft Authenticator app is highly recommended as it relies on internet connectivity rather than cellular SMS delivery.

Solution 2

Complete the Account Recovery Process

Follow these steps if you do not have any alternative verification methods available or if your phone number has changed.

Solution 3

Update Your Security Information

Once you regain access to your Microsoft account, update your security settings to prevent future lockouts.

Frequently Asked Questions

Why is my Microsoft verification text delayed?

Delays can occur due to carrier filtering, temporary network congestion, or account-security protocols on Microsoft's end. Waiting a few minutes or moving to an area with a stronger signal can sometimes resolve the issue.

Can I get blocked for requesting too many verification codes?

Yes. If you repeatedly click 'resend code' in a short period, Microsoft may temporarily block your phone number from receiving SMS codes to protect your account from spam or brute-force attacks. You will need to wait up to 24 hours before trying again.

What happens if I change all my security information?

If you lose access to all your security methods and change them entirely, Microsoft imposes a 30-day waiting period. During this time, you can still use your devices and access your email, but you cannot change sensitive settings or make purchases.
