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 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 vehicle registration plate, also known as a number plate, license plate or licence plate, is a metal or plastic plate or plates attached to a motor vehicle or trailer for official identification purposes. The registration identifier is a numeric or alphanumeric code that uniquely identifies the vehicle within the issuing authority's database. In Europe most countries have adopted a format for registration plates that satisfies the requirements in the Vienna Convention on Road Traffic, which states that cross-border vehicles must display a distinguishing code for the country of registration on the rear of the vehicle. 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.
The registration plates of cars in Norway are maintained by the Norwegian Ministry of Transport and Communications. As in most countries, cars are identified only by number plates read visually.

The Portuguese vehicle registration plate system for automobiles and motorcycles is simple and sequential. The system has no link to geographical locations or similar. It is an incremental numbering system consisting of three groups of two characters, separated by dashes. This system started in 1937 with AA–10–00, which ran out on 29 February 1992. This then went on to 00–01–AA and changed to 00–AA–01 in 2005. This last sequence was exhausted early in 2020, and it was announced on 3 March that it had been replaced by the sequence AA–00–AA. Moreover, the letters W and Y, never before used, and the letter K, used only for a short-lived series for imported vehicles in 1997, are being employed in the new system, meaning that this sequence should last more than six-and-a-half times as long as the previous. At current rates that it would not need replacing at least until the end of the 21st century, but the expected lifetime of the series is stated as being forty-five years.

Regular-issue license plates for passenger vehicles typically have six or seven characters, with vanity plates having up to eight characters in a few states.
