Updating Your Account Information
If you need to update your account information, read on.
Update Address
If you have recently moved house, you will need to inform us of your new address.
- Prepay customers can update their address on their My3 account.
- Bill Pay customers will need to contact Customer Care. We will then update your account. Once your address has been updated, any future bills or letters will be sent to your new address.
Update Married Name
To change the surname on your account to your new married name, visit a Three store with your marriage certificate. We will take a copy of it and then we will change your name on our systems.
Update Permissions and Preferences
To change your preferences on My3, log in and select 'Permissions & Preferences'.
Any changes made via My3 can take up to 24 hours to apply.
