Prefix Number Plates: The Complete Guide

Prefix number plates are UK registrations that begin with a letter identifying the age of the vehicle, followed by one to three numbers and three letters. They were issued to new vehicles between August 1983 and August 2001, before being replaced by the current number plate system.

A typical prefix registration takes the form A123 ABC. The A at the beginning is the age identifier, while the numbers and final three letters make up the rest of the registration.

Prefix registrations are particularly popular as private number plates because the three letters at the end can represent initials, names or words, while low numbers can make the registration considerably shorter and more distinctive.

What is a prefix number plate?

A prefix number plate is a registration where the first letter identifies the registration's age.

The format consists of:

one letter at the beginning;
one, two or three numbers; and
three letters at the end.

Examples include:

A1 ABC
A12 ABC
A123 ABC

The opening letter is known as the prefix, which is where the format gets its name.

When were prefix number plates introduced?

Prefix number plates were introduced in August 1983.

Before this, Great Britain used suffix registrations, where the age-identifying letter appeared at the end of the registration. The new prefix system moved the age letter to the beginning.

Prefix registrations remained the standard format for new vehicles until 31 August 2001. The current-style registration system was introduced on 1 September 2001.

What year is my prefix number plate?

The first letter of a prefix registration identifies when the registration was originally issued.

For most of the prefix era, a new letter was introduced every August. This changed in 1999, when new age identifiers began being released twice a year.

A – August 1983 to July 1984
B – August 1984 to July 1985
C – August 1985 to July 1986
D – August 1986 to July 1987
E – August 1987 to July 1988
F – August 1988 to July 1989
G – August 1989 to July 1990
H – August 1990 to July 1991
J – August 1991 to July 1992
K – August 1992 to July 1993
L – August 1993 to July 1994
M – August 1994 to July 1995
N – August 1995 to July 1996
P – August 1996 to July 1997
R – August 1997 to July 1998
S – August 1998 to February 1999
T – March 1999 to August 1999
V – September 1999 to February 2000
W – March 2000 to August 2000
X – September 2000 to February 2001
Y – March 2001 to August 2001

The letters I, O, Q, U and Z were not used as prefix age identifiers.

Can a prefix plate go on any car?

No. Unlike a dateless registration, a prefix plate contains an age identifier.

A private registration cannot be assigned to a vehicle if it would make that vehicle appear newer than it actually is.

For example, a K-prefix registration was issued from August 1992. It can be assigned to an eligible vehicle registered from that period onwards, but it cannot be put on a vehicle first registered in 1990 because it would make the vehicle appear newer.

Can I put an A-prefix plate on a new car?

Yes.

An A-prefix registration can be assigned to a modern eligible vehicle because it would make the vehicle appear older rather than newer.

The age rule only prevents a registration being used where its age identifier would make the receiving vehicle appear newer than its true age.

What letters were not used on prefix number plates?

The normal prefix age-letter sequence skipped I, O, Q, U and Z.

This is why the sequence moves from H to J, N to P, P to R, T to V and finally ends at Y.

A registration beginning with Q is different from an ordinary prefix registration. Q registrations are used in circumstances where a vehicle's age or identity cannot be established and are subject to separate rules.

How much is a prefix number plate worth?

Prefix registrations cover an enormous range of values.

Many standard prefix registrations remain relatively inexpensive. DVLA currently offers numerous prefix registrations from £250, with the advertised fixed price including VAT and the £80 assignment fee. More desirable combinations can be worth thousands or tens of thousands of pounds, while the very best examples have sold for more than £200,000.

The main factors affecting value include:

The number

Low numbers are normally more desirable than high numbers.

A prefix registration containing the number 1 can be particularly attractive because it shortens the registration and can help create a name or word.

The final three letters

The three-letter ending can represent initials, a name, a business or a recognisable word.

A common name or set of initials generally creates a much larger potential buyer market than an arbitrary combination.

How well the registration reads

The strongest prefix registrations often use the opening letter and number as part of the word itself.

K1 NGS, N1 GEL and P1 ANO are good examples of how the complete registration can resemble a recognisable word or name.

Previous sales

Comparable sales are one of the most useful ways to establish what a prefix registration may be worth.

Our Number Plate Sales Explorer contains more than 220,000 recorded UK number plate sales, including historic prefix registrations sold through DVLA auctions and other public sales.

Current competition

A registration may have strong initials or a good number but still be difficult to sell at a high price if several similar alternatives are available for substantially less.

The most expensive prefix number plates ever sold

The very best prefix registrations can achieve exceptional prices, particularly when the registration resembles a recognisable name or word, contains the number 1 or combines both qualities.

Below are the 15 most expensive publicly recorded prefix number plate sales in our database, ranked by the total recorded sale price including auction fees and taxes where applicable.

K1 NGS – £239,192 total (£185,000 hammer), DVLA, December 1993

The results show how important readability can be. Registrations resembling names or words such as K1 NGS, P1 ANO, N1 GEL, S1 MON and N1 CKY have all achieved particularly strong prices.

Are prefix number plates cheaper than dateless plates?

Generally, yes.

There are far more prefix combinations available than the shortest historic dateless registrations, and many standard examples can still be bought relatively cheaply.

However, format alone does not determine value. An exceptional prefix registration that clearly represents a name or word can be worth significantly more than an ordinary dateless registration.

At the very top of the market, the best dateless registrations still tend to achieve higher prices because of their extreme scarcity and lack of an age identifier.

Are prefix number plates a good investment?

Some prefix registrations have increased substantially in value, but there is no guarantee that a registration will appreciate.

The strongest examples usually have characteristics that create long-term buyer demand:

a low number, particularly 1;
a common name or initials;
a recognisable word;
short and memorable presentation;
strong historic sale evidence; and
few close alternatives available.

A registration should be valued on the strength of the individual combination rather than simply because it is a prefix plate.

Can I still buy prefix number plates?

Yes.

Prefix registrations are still widely available even though they have not been issued as the standard registration format for new vehicles since 2001.

Frequently Asked Questions

What does prefix number plate mean?

A prefix number plate is a UK registration where the first letter acts as the age identifier. It is followed by one to three numbers and three letters, for example A123 ABC.

When were prefix plates used?

Prefix registrations were issued to new vehicles between August 1983 and August 2001.

What was the first prefix registration letter?

A was the first prefix age identifier and was used from August 1983 until July 1984.

What was the last prefix registration letter?

Y was the final prefix age identifier and was used from March to August 2001 before the current registration format was introduced in September 2001.

Why were I, O, Q, U and Z not used as prefix letters?

These letters were excluded from the normal age-identifier sequence. Some could easily be confused with numbers or had other uses within the registration system. A Q registration, for example, has a separate meaning and is not an ordinary prefix age registration.

Can I put a prefix plate on an older car?

Only if the prefix would not make the vehicle appear newer than it actually is. A registration cannot be assigned if its age identifier represents a later registration period than the vehicle.

Can I put a prefix plate on a newer car?

Yes. An older prefix registration can generally be assigned to a newer eligible vehicle because doing so does not make the vehicle appear newer.

Are prefix number plates valuable?

Some are. Standard prefix registrations can be relatively inexpensive, while plates containing low numbers, desirable initials, names or recognisable words can be worth thousands or even hundreds of thousands of pounds.

How much do prefix number plates cost?

DVLA currently offers many standard prefix registrations from £250, including VAT and the £80 assignment fee. Rare or highly desirable registrations can sell for much more, with publicly recorded prefix sales exceeding £200,000.

What is the most expensive prefix number plate ever sold?

The highest publicly recorded prefix registration in our sales database is K1 NGS, which sold through DVLA in December 1993 for a £185,000 hammer price and approximately £239,192 including the recorded fees and taxes.

Can I transfer a prefix registration?

Yes – see our number plate transfer guide. It can be transferred provided the registration is transferable and the receiving vehicle meets the normal eligibility and age requirements.

Can I sell a prefix number plate?

Yes. Prefix registrations can be sold while assigned to a vehicle or while held on a valid V750 or V778, although the transfer process will differ depending on where the registration is held.

How do I value a prefix number plate?

Look at genuine previous sale prices for similar registrations and consider the number, final three letters, readability, initials or name represented, current competition and overall buyer demand. Dealer asking prices alone should not be treated as proof of market value.
