If you want to change the vehicles on your account, and use your tag in the new vehicle, you can do this online.
To reassign your tag:
If your tag has been successfully reassigned, you will see a confirmation message.
Please note: If the vehicle that you’re trying to add is already registered to another account then you will be unable to do so vehicle until the vehicle is removed from the other account.
If you need a new tag holder for any vehicle, you can request it by clicking on the blue 'wheel' icon in the 'Options' column (to the right of each vehicle's details).
Please note: you cannot reassign a tag to a different vehicle type (e.g. you cannot change from a van to a car or vice versa).
