British plates since 1 September 2001 read as two letters, two age digits, and three letters: AA11 AAA. The first pair is a memory tag for the office area. The digits are the age identifier, which changes twice a year. The last three letters are the random sequence. The plate article records 24 for March–August 2024 and 74 for September 2024–February 2025; an age mark is tied to a registration period, not today’s year.
White in front, yellow behind
The front plate is white. The rear plate is yellow. Characters are black, and the material is reflective. If a mockup shows yellow on the bonnet, it is the wrong end of the car. Draw two PNGs if the shot needs both bumpers.
The legal face and the standard
The prescribed face is called Mandatory, the Charles Wright design from 2001. Character width in the rules is 50 mm and height 79 mm on a car. Motorcycle characters are 64 mm tall. The standard in force since 1 September 2021 is BS AU 145e, which replaced 145d. A preview font is not that face. Treat the download as spacing practice: two letters immediately followed by two digits, a space, then three letters.
Northern Ireland is the exception inside the UK article: it still uses a pattern like ABC 1234 and is not part of the age-identifier system. I keep that as one sentence so a Belfast mockup does not inherit a London age mark.
Build the string in the preview. Country-to-country differences in the blue band, where a country still uses one, are on the Europe page.
Questions
Why say number plate instead of license plate?
UK searches use number plate. The H1 matches that wording. The format is still AA11 AAA.
What about Northern Ireland?
Northern Ireland keeps ABC 1234. I do not paint it as an AA11 AAA plate.
