A vehicle registration plate, also known as a number plate or license plate or licence plate, is a metal or plastic plate attached to a motor vehicle or trailer for official identification purposes. All countries require registration plates for commercial road vehicles such as cars, trucks, and motorcycles, for hire. 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.

This sign may be an oval sticker placed separately from the registration plate, or may be incorporated into the plate. When the distinguishing sign is incorporated into the registration plate, it must also appear on the front plate of the vehicle, and may be supplemented with the flag or emblem of the national state, or the emblem of the regional economic integration organisation to which the country belongs. An example of such format is the common EU format, with the EU flag above the country code issued in EU member states.
