What Defines a Prefix Number Plate?

Prefix number plates were common in the UK from August 1983 through to July 2001, and they are one of the four primary vehicle registration systems in the country recognised by the Driver & Vehicle Licensing Agency. These plates are unique as they feature an initial letter which serves as an indicator of the registration year of the vehicle. They were initially designed to replace suffix plates when they had been exhausted in 1982.

The Anatomy of a Prefix Number Plates

  • The foremost letter acts as the age identifier. For example, ‘A’ represents vehicles registered from August 1983 to July 1984.
  • Following the age identifier are three arbitrary numbers that uniquely identify the vehicle from others registered during the same period.
  • The final two letters or final three letters usually signify the area code, such as ‘AN’ for Reading.

Why Are Some Letters Missing in Prefix Plates?

You will notice that some letters are missing from the prefix system. There are a few reasons for this, mostly to assist with further identification. For example, the letters ‘I’ and ‘Z’ are exclusively reserved for Northern Ireland, while the letters ‘O’ and ‘U’ are omitted to prevent confusion with similar looking values – the number ‘0’ and letter ‘V’ respectively. Finally, the letter ‘Q’ is reserved for vehicles with unconfirmed manufacturing dates.

The Issuance Schedule for Prefix Plates

Originally, the prefix system supplanted the older suffix style registration system in August 1983. Initial demand led to an annual release each August. To mitigate this rush, the system was revised to a biannual issuance from August 1984. This, however, expedited the depletion of available prefix combinations, resulting in the adoption of the current registration system in 2001.

Restrictions on Using Prefix Number Plates

While transferring plates between cars is common, prefix plates have limitations. They can’t be fitted on vehicles registered before August 1983 as it’s against the law to make a car appear younger than it actually is.
