Prefix number plates, issued between 1983 and 2001, are the most affordable private plates in the UK. Most sell for a few hundred pounds. But when the letters and numbers line up to spell a name or word, a prefix plate can be worth six figures. Here's what prefix plates really sell for, and what separates a £300 plate from a £100,000 one.

The Prefix Plates That Sold for the Most
These are some of the highest public sales of prefix plates in the UK. Almost every one spells a name or a word.

Prices as reported at the time of sale, including auction fees and VAT where applicable.
What these plates have in common is that the year letter at the front starts the word, and a 1 or a 4 stands in for a letter. That combination is rare, which is why these plates sit so far above the rest of the market.
Our analysis
What Most Prefix Plates Are Really Worth
Prefix Plates in a 2,000-Lot Auction
To see what an everyday prefix plate sells for, our team analysed the results of a recent 2,000-lot number plate auction. 447 prefix plates sold, with a median winning bid of £610.
| Price band | Prefix plates sold | Share of prefix plates |
|---|---|---|
| £500 or less | 191 | |
| £501 to £1,000 | 101 | |
| £1,001 to £2,000 | 88 | |
| £2,001 to £5,000 | 57 | |
| Over £5,000 | 10 |
Winning bids, excluding buyer's fees and VAT. Unsold lots are not included.
Two in three prefix plates sold for £1,000 or less, and the cheapest went for £200. Only 10 of the 447 sold for more than £5,000. The highest was H49 RRY (Harry) at £10,100.
Why Prefix Plates Are the Most Affordable Private Plates
Prefix plates had a lower median than suffix, Northern Irish or current-style plates in the same auction. Their median of £610 compares with £1,260 for suffix plates, £1,275 for Northern Irish plates and £1,310 for current-style plates. There are three main reasons:
- There are a lot of them. Prefix plates were issued for 18 years, so there are a great many in circulation.
- They're long. Almost all have two or three numbers, which makes it harder to spell a clean name or word.
- The year letter limits which cars they fit. A late prefix plate, such as an X or Y, can't go on a car from the 1990s.
"Most prefix plates are worth a few hundred pounds, and we'd rather tell owners that honestly than give them a number they'll never achieve. But every so often a prefix plate spells a name perfectly, and those can be worth many times the average. That's why every plate deserves a proper look."

The basics
The Year Letter Comes First: How Prefix Plates Work
How to Read a Prefix Plate
A prefix plate follows the pattern A123 BCD:
- The first letter is the year identifier, the "prefix" that gives the format its name.
- The numbers run from 1 to 999.
- The last three letters are made up of a random letter followed by a two-letter area code showing where the car was first registered.
Prefix Year Letters From A (1983) to Y (2001)
Prefix year letters changed every August until 1998, then every six months from 1999.
- AAugust 1983 to July 1984
- BAugust 1984 to July 1985
- CAugust 1985 to July 1986
- DAugust 1986 to July 1987
- EAugust 1987 to July 1988
- FAugust 1988 to July 1989
- GAugust 1989 to July 1990
- HAugust 1990 to July 1991
- JAugust 1991 to July 1992
- KAugust 1992 to July 1993
- LAugust 1993 to July 1994
- MAugust 1994 to July 1995
- NAugust 1995 to July 1996
- PAugust 1996 to July 1997
- RAugust 1997 to July 1998
- SAugust 1998 to February 1999
- TMarch 1999 to August 1999
- VSeptember 1999 to February 2000
- WMarch 2000 to August 2000
- XSeptember 2000 to February 2001
- YMarch 2001 to August 2001
The letters I, O, Q, U and Z were never used as year letters, to avoid confusion with numbers and other letters.
Names and words
Turning the Year Letter Into a Name
Names That Start With the Year Letter
On a prefix plate, the year letter comes first, so it can start a name or word. The numbers then fill in missing letters: 1 for I, 4 for A, 5 for S and so on. That's how H49 RRY reads as Harry, J42 MES as James and M1 KES as Mikes.
The most valuable prefix plates read naturally with correct spacing. Plates can't legally be mis-spaced on the road, so a plate that only works with creative spacing is worth far less.
Singh Plates and Other Surnames
Surname plates are a big part of the prefix market. Singh plates are especially popular, and J451 NGH sold for £10,010 in our auction analysis, the second highest prefix plate in the sale. P91 NGH made £3,560.
Single-Number Prefix Plates: The Rarest of the Format
Prefix plates with just one number, such as A1 ABC, are far rarer than the usual three-number style. Only one of the 447 prefix plates in our auction analysis had a single number: G4 OOO, which made £2,610. The six-figure sales above show what a single-number prefix plate can achieve when it spells something.
Year letters
Does the Year Letter Affect the Value?
A little. In our auction analysis, H and F prefix plates had the highest median winning bids, at around £1,000. E, P, R and T plates had the lowest, at around £350.
The most likely reason is names. More popular first names start with H, J or S than with E, P or T, so plates with those year letters have more chances to spell something people want. The age of the plate itself makes little difference.
Which cars
Can I Put a Prefix Plate on My Car?
Almost certainly, yes. A prefix plate can go on any car first registered on or after the date of its year letter, because a plate can't make a vehicle look newer than it is.
- An H-prefix plate (1990 to 1991) can go on any car registered from August 1990 onwards.
- It can't go on a car registered in 1988, because it would make that car look newer.
Since the last prefix plates were issued in 2001, any car registered since then can take any prefix plate.
Compare
Prefix or Current Style: How Do They Compare?
Prefix and current-style plates are the two most affordable ways to put a name on a plate, so buyers often weigh one against the other. Each has its strengths:
Prefix (A123 BCD)
- Issued
- 1983 to 2001
- Typical value
- £200 to £20,000+
- Spelling names
- The year letter can start a name, and 1 to 3 numbers give flexibility
- Which cars
- Any car registered after the year letter
- Shows a car's age
- Yes, to within a year (six months from 1999)
Current style (AB12 CDE)
- Issued
- 2001 onwards
- Typical value
- £250 to £11,500+
- Spelling names
- The numbers are fixed to the age identifier, so fewer combinations spell a name
- Which cars
- Only cars registered after the age identifier
- Shows a car's age
- Yes, to within six months
Prefix plates often give more flexibility for spelling a name, and because they're older they can go on far more cars than a recent current-style plate.
Selling
Selling a Prefix Plate: Setting a Realistic Price
Because most prefix plates sell for under £1,000, the price you set matters. A few things to know before you sell:
- What you paid isn't what it's worth. If you bought a prefix plate new from a dealer, the price included their margin and DVLA fees. Its resale value is often lower.
- Asking prices aren't sale prices. Plates listed online are often priced well above what they actually sell for.
- Names sell, random plates wait. A prefix plate that spells a name will find a buyer far faster than a random combination.
Have your V5C logbook ready if the plate is on a car, or your V778 retention certificate or V750 certificate of entitlement if it isn't.

FAQs
Prefix Plate Questions
What is a prefix number plate?
A prefix number plate is a UK registration issued between 1983 and 2001. It starts with a year letter, followed by one to three numbers and three letters, such as A123 BCD.
What years are prefix plates?
Prefix plates run from A (August 1983) to Y (August 2001). From 1999, the year letter changed every six months.
Can I put a prefix plate on a newer car?
Yes. A prefix plate can go on any car first registered on or after the date of its year letter, including any car registered since 2001.
Are prefix plates worth anything?
Yes, although most are worth a few hundred pounds. In a recent 2,000-lot auction, the median prefix plate sold for £610. Plates that spell a name or word can be worth thousands, and the very best over £100,000.
Why are prefix plates cheaper than suffix plates?
There are more of them, most have three numbers that make names harder to spell, and later year letters can't go on older cars. In the same auction, prefix plates sold for about half the median of suffix plates.
