A vehicle registration plate, also known as a number plate or license plate, 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.

In Sweden, vehicle registration plates are used for most types of vehicles. They have three letters first, a space and two digits and one digit or letter after. The combination is mostly a random number and has no connection with a geographic location. The last digit is used to show what month the vehicle tax has to be paid, and before 2018 it was also used to show what month the car had to undergo vehicle inspection. Vehicles like police cars, fire trucks, public buses and trolley buses use the same type of plate as normal private cars and cannot be directly distinguished by the plate alone. Military vehicles have special plates. Part of the vehicle data is public and can be retrieved online.
