i tried to change my phone number because its been a year that I've had a new one and when i tried to change it i got asked for a pin that was going to be sent to my old phone number but i got a option to send a security email to my second email but when i put my information on the email to try and change my number i was told that my information was going to be transferred and i could do anything with my account. I called support and asked for help but i was just told that my account will be locked after 30 days which I don't want. All I wanted to do was change my old phone number to my new one.

My friend was unable to create parties after signing into my account on his Xbox. Im having some troubles changing my privacy settings as I no longer have access to an old phone number (A code has been sent to the old number because I cant just 'access important
information'

Since it takes a month for the phone number change process, would customer service be able to change my settings for me or do I have to wait?

I do not have access to the phone number linked to my account. When I try to sign into my account on a new device, the login requires a code from the old phone number. How do I access my account without the phone number?I am trying to sign in to a different Xbox One than my personal Xbox. I am unable to access my personal Xbox at present. I cannot get into my Xbox Microsoft account to change my verification phone number without the old phone number, which I no longer have.

When you first setup two step verification (where it sends a verification code to your phone number when logging in) it wouldve provided you with several backup codes (meant for this exact sort of situation) and told you to save them in safe place.

You can use one of those codes instead when it asks you for a code.

If on the off chance you didn't save those codes then unfortunately your account wont be recoverable. Those backup codes are your absolute last resort for regaining access to the account in this sort of situation. This is also why its so very important to keep your account information up to date.

I would like to change my old phone number to my new number
