A vehicle registration plate, also known as a number plate (British English), license plate (US English) or licence plate (Canadian English), is a metal or plastic plate attached to a motor vehicle or trailer for official identification purposes. All countries require registration plates for road vehicles such as cars, trucks, and motorcycles. Whether they are required for other vehicles, such as bicycles, boats, or tractors, may vary by jurisdiction. The registration identifier is a numeric or alphanumeric ID that uniquely identifies the vehicle or vehicle owner within the issuing region's vehicle register. In some countries, the identifier is unique within the entire country, while in others it is unique within a state or province. Whether the identifier is associated with a vehicle or a person also varies by issuing agency. There are also electronic license plates. A car registration plate from the United Kingdom. The "GB" or "UK" marks have been used in the United Kingdom in various years In Europe, most governments require a registration plate to be attached to both the front and rear of a vehicle, although certain jurisdictions or vehicle types, such as motorcycles, require only one plate, which is usually attached to the rear of the vehicle. Special vehicles such as agricultural and construction equipment might have the license plate attached to other parts of the vehicle. National databases relate this number to other information describing the vehicle, such as the make, model, colour, year of manufacture, engine size, type of fuel used, mileage recorded (and other similar data in jurisdictions where vehicles are regularly inspected for roadworthiness every year or two), vehicle identification number (chassis number), and the name and address of the vehicle's registered owner or keeper. In the vast majority of jurisdictions, the government holds a monopoly on the manufacturing of vehicle registration plates for that jurisdiction.
