From the earliest dateless registrations to modern current style plates, UK number plates have told the story of motoring for over a century.
As motor vehicles became more common in the early twentieth century, a reliable way was needed to identify vehicles and their keepers. Registration numbers allowed authorities to record vehicles, issue licences and trace vehicles when required.
Over time, number plates became more than just a legal requirement. Dateless, suffix, prefix and current style registrations are now also collected, bought and sold as private number plates.
The Motor Car Act 1903 introduced compulsory vehicle registration in Great Britain. Local authorities were allocated letter codes and issued registration numbers in sequence.
Early examples had no age identifier, which is why they are now known as dateless registrations.
Dateless registrations usually consisted of one or two letters followed by up to four numbers. The letters identified the local licensing authority, while the numbers were issued sequentially.
Because these plates do not show a vehicle age, dateless registrations remain among the most desirable private number plates.
As vehicle numbers increased, some areas began to run out of combinations. To create more registrations, an extra serial letter was added before the original area code.
Some councils later reversed the format, placing the numbers before the letters. This created more available registrations while keeping the area code system in place.
Suffix registrations introduced a year letter at the end of the number plate. This meant the registration could now indicate the year in which it was issued.
Suffix plates are popular with classic vehicle owners who want a registration that matches the age and character of their vehicle.
Vehicle registration administration gradually became more centralised, with responsibility moving away from local authorities and into the modern DVLA system.
This helped create a more consistent national approach to issuing, transferring and managing registration numbers.
Prefix registrations reversed the suffix format by placing the year identifier at the beginning of the registration. This format remained in use until 2001.
The current registration format was introduced in September 2001. The first two letters identify the issuing region, the two numbers show the vehicle age, and the final three letters are randomly issued.
New age identifiers are released twice each year, in March and September.
Green number plates were introduced for eligible zero-emission vehicles. The green flash makes electric vehicles easier to identify and supports clean vehicle initiatives.
Many pre-1973 registrations contain one, two or three letter combinations which identify the original licensing authority responsible for issuing the number plate. These historic area codes can help determine where a vehicle was first registered and are often useful when researching classic cars, old photographs and vintage documents.
For example, registrations containing ND were associated with Manchester, while other letter combinations were allocated to different towns, cities and counties throughout the UK.

Older number plate formats remain highly popular today. Dateless plates are prized because they hide vehicle age, while suffix and prefix registrations are often chosen to match a classic car’s period.
PrimoReg offers thousands of private registrations across different formats, including dateless number plates, suffix plates, prefix plates and current style registrations.
