Vehicle registration plates (commonly referred to as "number plates" in British English) are the alphanumeric plates used to display the registration mark of a vehicle, and have existed in the United Kingdom since 1904. It is compulsory for motor vehicles used on public roads to display vehicle registration plates, with the exception of vehicles of the reigning monarch used on official business.^[1]

The Motor Car Act 1903, which came into force on 1 January 1904, required all motor vehicles to be entered on an official vehicle register, and to carry alphanumeric plates. The Act was passed in order that vehicles could be easily traced in the event of an accident, contravention of the law or any other incident. Vehicle registration alphanumeric plates in the UK are rectangular or square in shape, with the exact permitted dimensions of the plate and its lettering set down in law. Front plates are white, rear plates are yellow.

Within the UK itself, there are two systems: one for Great Britain, whose current format dates from 2001, and another for Northern Ireland, which is similar to the original 1904 system. Both systems are administered by the Driver and Vehicle Licensing Agency (DVLA) in Swansea. Until July 2014, Northern Ireland's system was administered by the Driver and Vehicle Agency (DVA) in Coleraine, which had the same status as the DVLA. Other schemes relating to the UK are also listed below. The international vehicle registration code for the United Kingdom is UK.^[2] Prior to 28 September 2021, it was GB.^[3] The specification of plates incorporating the UK code was created by the British Number Plate Manufacturers Association, and is seen as the default design by the Department for Transport.^[4]
