Unknown 2FA Phone Number

I don't know my 2FA phone number (I only had that phone for a week). So I am unable to change passwords or (now) unlock accounts. iforgot.apple.com wants you to fill in the phone number in order to get a OTP.

When you set up the Apple Account, you would have been required to have a number that is used for Two Factor Authentication. By default it will be the number of the device when you set up the account and you can add or edit the numbers after set up.


Without providing that 2FA phone number or having another Trusted Device, which is one currently signed into your account, you will need to use Account Recovery. There will likely be a delay before you are allowed to change the password using this method, instead of immediately being able to change it with the 2FA phone number.

How to use account recovery when you can’t reset your Apple Account password - Apple Support


Once you gain access to your account, you will want to review your Trusted Phone number, where you can add or edit what you see there. It is not possible to do that when you are not able to access your account.
