CHANGE PHONE NUMBER

Select I don’t have any of these when Microsoft asks for a code, then follow the prompts to replace the expired phone number with new security information.

If the old number is your only verification method

1. Start signing in to your Outlook.com/Microsoft account.
2. On Verify your identity, select I don’t have any of these.
3. Follow the prompts to provide and verify new security information.
4. After replacing all security information, Microsoft requires a 30-day waiting period before you can sign in with the replacement information.^1^

Do not repeatedly request codes for the expired number, because excessive requests can trigger a temporary block.

If you can use another verification method

If the account also offers a working recovery email, Microsoft Authenticator, or another method:

1. Sign in to the Microsoft account Security page.
2. Select Manage how I sign in.
3. Select Add a new way to sign in or verify.
4. Add and verify the new method.
5. Expand the old phone-number entry and select Remove.^2^

A new phone-number option might not appear because Microsoft is phasing out SMS for personal accounts. If it is unavailable, add a recovery email, Microsoft Authenticator, or a passkey instead.^2^

Microsoft Support cannot send the verification code or manually change protected account details, so the I don’t have any of these replacement process is the required path when no existing method remains accessible.^1^
