All new and imported vehicles are required to be entered onto the register which is administered by the Driver and Vehicle Licensing Agency (DVLA) in Great Britain and by Driver & Vehicle Agency (DVA) in Northern Ireland.
Registered vehicles are provided with a unique registration number which has to be displayed on the vehicle on specified registration plates.
On the register, along with the vehicle details (make, model, engine capacity, colour, VIN, etc.) are recorded the details of the current keeper of the vehicle (name, address). The current keeper is issued with a registration document known as a V5C, which displays the registration details of the vehicle. Each time any of the registration details change, if the vehicle keeper is changed, or any of the vehicle details are changed, for example, the DVLA/DVLNI has to be notified, and a new document is issued.
A vehicle first registration fee has to be paid to enter a vehicle onto the register for the first time.
Details from the database are also available, for a fee, to anyone having a good reason to require them.
