Current plates have been continually issued since 2001, and offer a vast array of possible combinations. [1]
Prefix plates were used between 1983 and 2001, so they are limited in number and generally of higher value.
Suffix plates were first introduced in 1963 and used until 1983. The final letter is the age identifier and changed.
Dateless plates were issued before 1963 and do not contain any age identifier, making them highly desirable and timeless.

Each section outlines how the format works, what the characters mean, and the rules for using them — helping you choose the option that best suits your vehicle and preferences.
How UK Number Plate Formats Work
UK number plate formats follow set structures that identify when and how a registration was originally issued. Each format uses a different combination of letters and numbers, with some including an age identifier and others — such as dateless number plates — containing no age marker at all.
Age-related registrations can only be assigned to vehicles of the correct year or newer, while dateless registrations offer maximum flexibility and are suitable for most vehicles. Under DVLA rules, a number plate must never make a vehicle appear newer than it is.
Understanding UK number plate formats is essential when buying, selling, or transferring a private registration. This guide explains how each format works, what the characters mean, and how to choose the right type of number plate for your vehicle.

This original car registrations series included the combinations A1-YY9999. The letter component (either single character or a pair) identified the local authority in whose area the vehicle was registered (A, for example, indicated a vehicle registered in London). The number component simply incremented and provided the unique identification for the bearer vehicle within the area shown by its letter code.
In England and Wales the area letter codes were assigned alphabetically according to the size of the population in each authority’s area, hence crowded London’s allocation of the ‘A’ designation.
In Scotland and Ireland the system worked a little differently. Registration in those regions began with the letter S in Scotland and I in Ireland. These national identifiers would be followed by another letter which, like the English and Welsh versions, specified the local registering authority, and then by the sequential ID number.
In the areas of greatest demand, yet another extension was introduced within a decade, this time using the range 1A -9999YY.
