Suffix Number Plates Explained

Suffix number plates are a historic UK registration format used on vehicles first registered between January 1963 and July 1983. They are easily recognised by a single letter at the end of the plate, following up to three letters and up to three numbers.

Examples:

ABC 123A

ABC 12A

ABC 1A

This style of registration has been strongly associated with classic and historic vehicles and remains popular today for vehicle owners of all ages.

How Do Suffix Plates Work?

A suffix number plate follows this format:

[Letters] [Numbers] [Suffix Letter]

First letters – Original issuing area identifiers
Numbers (1–999) – Random issue numbers
Suffix letter – Indicates the year of first registration (age identifier)

The format is distinctive and instantly recognisable, making it a natural choice for classic vehicles.

The suffix system was introduced by the Driver and Vehicle Licensing Agency (DVLA) as the first UK registration style to clearly identify a vehicle’s age.
In 1983, the suffix system was replaced by the prefix format, increasing the rarity and desirability of suffix registrations.

Why Are Suffix Plates Still So Popular?

Suffix plates remain in demand because they:

Look authentic on classic and vintage vehicles
Preserve historical accuracy and originality
Are highly regarded by collectors and enthusiasts
Complement restorations and period-correct builds
Are commonly used to mark birth years, anniversaries, or names
Can be great investments

These qualities make suffix plates especially appealing within the classic car community.

Rules for Using Suffix Number Plates

Suffix number plates are also age-related registrations and are subject to the same restrictions.

A suffix plate can only be assigned to a vehicle that was registered in the same year or later than the suffix letter indicates.
It is not permitted to assign a suffix plate to a vehicle if it would make the vehicle appear newer than its actual registration date.

These rules are administered by the Driver and Vehicle Licensing Agency (DVLA).
