I have had a new phone number. I went into MSN to change the phone number, and the only choice was to delete the old number. The system will not allow me to enter a new number under any circumstances, and this makes it so I cannot get a confirm code, because it keeps sending the code to the old number. I cannot access customer support either.

Hey there! Nice to meet you!

Unfortunately, it is no longer possible to add a phone number as a verification method, as Microsoft has stated that they have already phased this option out, particularly under "Note" https://support.microsoft.com/accounts-billing/manage/microsoft-account-security-info-verification-codes

However, you can add three or more security methods to your account to provide additional verification options, such as a recovery email address, a passkey, and Microsoft Authenticator on account.microsoft.com > Security > Manage how I Sign in > Then click on "Add another way to sign in to your account"

Thank you for your understanding.

Best regards,

Darhyl

    If you didn’t setup alternative authentication methods, you will need to use the account recovery page.

    https://support.microsoft.com/en-us/accounts-billing/manage/help-with-the-microsoft-account-recovery-form

    Note: there is no contact phone number, only the recovery form. While you will get validation of recovery in 24 hours, there is a 30 day delay before actual recovery. This allows warning messages to be set to the email and chances to cancel request if fraudulent.
