Prefix Style Number Plate Dates (Full UK Registration List)

This guide explores Prefix Style Number Plate Dates in the UK, including the full list of registration letters used between 1983 and 2001 — with the exact month ranges each prefix was issued. Prefix registrations replaced the suffix format that came before it and remained in use until the modern current-style format began in 2001. Understanding historic number plate formats helps identify vehicle age, compare registration systems, and recognise classic UK plates.

Prefix Style Number Plates

What Are Prefix Style Number Plates?

Prefix style registrations were introduced on 1 August 1983 and remained in use until 28 February 2001. Typical format:

A123 ABC
The first letter (prefix) indicates the vehicle registration period
Numbers and trailing letters form the unique identifier

Unlike suffix plates, prefix registrations changed every August until 1999, when a twice-yearly system (March and September) was introduced for the final years of the format.
