You can edit the phone number registered on your account by logging in online. Once logged in, you will need to head to ‘my stuff’ > ‘my account’ > ‘about me’.
To update your registered phone number, you will be prompted to verify your identity via SMS or email (you will have the option to choose between the two). You will then receive a 6-digit code that will expire in 10 minutes.
Once you have entered the 6-digit code, another code will be sent to your new phone number. Like the first code, you will be prompted to enter this as the final step for updating your contact number.
You will receive an email to advise of this change on the account.
