The documentation certifying ownership of a vehicle will be in the form of a Vehicle Registration Certificate (VRC) or Vehicle Licensing Certificate (VLC). These documents are also commonly known as the "Logbook". Which document your vehicle will have depends on when the last change of ownership was completed or the age of the vehicle. The Vehicle Registration Certificate (VRC) is the newer document and the Vehicle Licensing Certificate (VLC) is the older form of this ownership document.
The registration certificate number will be displayed in one of the two ways shown below.
For further information on these documents and how they relate to the change of ownership of a car please see the Citizens Information Website.
