Hello Jennifer,
Thank you for interacting with us by posting your issue on this forum.
It looks like you're unable to sign in because the verification code is being sent to an old phone number. To help you regain access, have you tried recovering the account with an alternate method, like email verification or security questions. If not, then try these steps:
- Choose an alternative recovery option: If available, select Recover through email instead of using your old phone number.
- Check for other verification methods: Some services allow identity confirmation through security questions or backup codes.
- Fill out the account recovery form: If neither option works, submit the account recovery form with accurate and detailed information to prove your identity. Here is the link: Recover your account
- For more details that How to Fill Account Recovery Form you can visit this Support Article Page: Help with the Microsoft account recovery form - Microsoft Support
Have an amazing day!
