Microsoft has two digits of my phone number incorrect.

Question

I am logged in, but when I try to do various things within the suite it says it sending my phone a code and the phone number on file is incorrect. How do I change two numbers of the phone number to have full access to the suite?

Answer 1

Hello, thank you for reaching out to Microsoft Q&A.

When you try to sign in and are asked to verify your identity, the verification code will be sent to the alternate phone number or email address that you previously added.

This typically happens when you try to access sensitive information in your account.

Do you have any other verification methods configured besides the incorrect phone number? If that is your only option, you will need to replace the security verification method on your Microsoft account.

On the "Verify your identity" screen, select I don't have any of these, and then follow the prompts to replace your security information.

Note: If you remove all your previous security information and replace it with new information, your account will be placed in a restricted state for 30 days. During these days, you will not be able to access any of the services that require your verification.

Answer 2

To change the incorrect digits of your phone number associated with your Microsoft account, follow these steps:

1. Go to the Microsoft Account Security Page: Visit the security section of your Microsoft account at account.microsoft.com/security.
2. Check Recovery Options: In the Security section, look for the Recovery options area and select Security info. Here, you should see your current phone number listed.
3. Remove the Incorrect Phone Number: If the number is incorrect, click on Remove next to the phone number.
4. Add Your Correct Phone Number: After removing the incorrect number, click on Add Security Info to enter your correct phone number.
5. Verify Changes: Ensure that the new phone number is correctly listed and check if you still receive prompts for the old number.

If you continue to experience issues, it may be helpful to check for any security alerts or required actions on your Microsoft account.
