Suffix Number Plates Explained: The 1963–1983 Year Letter, What They Cost and Who They Suit

TL;DR: A suffix plate is the three letters, one to three numbers, one year letter format used in Britain from February 1963 to 31 July 1983 — think BOB 1A or JAM 1S. The final letter dates the car: A = 1963, E = Jan–Jul 1967, F = the first of the 1 August year changes in 1967, Y = 1982/83. Because the letters come first, suffix plates read as three-letter names and initials better than any other dated format. Live examples on our own featured plates page today run from £1,995 (JEN 19F) to £125,000 (DAV 7D), with plenty between £3,000 and £10,000. You can put a suffix plate on any car of the same age or newer — never an older one.

What is a suffix number plate?

A suffix registration is built in three parts, always in this order:

The system arrived in February 1963 because local authorities were running out of dateless combinations, and ran until 31 July 1983, when the prefix format (A123 BCD) took over and moved the year letter to the front. Twenty years, twenty-one year letters, and most of the golden age of the British classic car sits inside it.

From 25 years in the trade: the question we get most often is "does the letter at the end have to match my car?" — and the answer is only in one direction. The registration can never be younger than the car. That single rule decides most of our suffix sales, so we ask for the vehicle's date of first registration before quoting.

What does the year letter on a suffix plate mean?

Here is the full run. I, O, Q, U and Z were never used as year letters — too easily confused with numbers, or reserved for other purposes.

Two oddities: A covers only eleven months (the scheme started in February 1963) and E only seven, for the reason below. Everything from F onwards is a clean August-to-July twelve months, which is why a "1972 car" can wear either K or L depending on which side of 1 August it left the showroom.

Why did the year change to 1 August in 1967?

Because the motor industry asked for it. Under the January changeover, buyers held off through the autumn to get the new letter in the New Year, leaving dealers a dead winter and a January stampede. Moving the change to 1 August 1967 pushed the rush into summer.

The result is the strangest year in the table: E ran for just seven months (January to July 1967) and F started on 1 August 1967, so 1967 is the only year with two year letters. The E/F split tells you which half of 1967 a car was registered in — useful when checking a plate against a logbook.

From 25 years in the trade: we still get calls from owners of early F-registered cars convinced the plate is "wrong" because the car is a 1967 model. It isn't — the August change caught out a whole model year, and an F suffix on a car first registered in September 1967 is correct.

Suffix or prefix — which suits your name better?

The practical difference between the two dated eras comes down to where the letters sit.

Suffix wins whenever the name is exactly three letters, because those letters are the first thing anyone reads: BEN 1Y, JEN 1S, ABB 9Y, DEN 21L. Prefix wins for a single initial and a low number. Compare the two in our sister guide, prefix number plates explained, and our overview of how to read UK number plates.

A third option people forget: dateless plates carry no year identifier at all and fit a vehicle of any age. They start at just under £750 with us.

How much do suffix number plates cost?

Real suffix registrations listed on our featured plates page as we wrote this, chosen to show the spread.

Prices are advertised asking prices on our own site, re-checked against our live stock on 29 August 2026; stock moves daily. Add the £80 DVLA assignment fee to every plate, and note that some marks also carry VAT (JEN 19F, UPE 5T and OLL 7S do; RAJ 32D does not) — the plate's own page shows the all-in figure. The table shows the shape of the market: a three-letter name with a low number (JAM 1S, BEN 1Y) sits an order of magnitude above the same name padded out with extra digits (JEN 19F, ALF 41S). If budget matters, the padded versions are where the value is.

From 25 years in the trade: the number moves the price more than the year letter does. Buyers fixate on matching a specific suffix letter to a car's build year, then baulk at the cost. Nine times in ten you get a better-looking plate by relaxing on the letter and spending the money on a one- or two-digit number. Ring 01526 353111 and we will price both before you commit.

Which cars can legally wear a suffix plate?

The DVLA rule is absolute: you can never make a vehicle look newer than it is. GOV.UK's guidance on assigning a private number is explicit on this. So:

• A 1975 (P-suffix) car can wear any suffix plate from A to P, or any dateless plate — but not an R, S or later suffix, and no prefix or current-style plate.
• A 2024 car can wear any suffix plate at all: making a car look older is permitted.
• A Q-registered vehicle (kit cars, rebuilds, age unknown) cannot take a private plate, and numbers starting Q or QNI cannot be assigned.

The vehicle must also be registered with the DVLA, move under its own power, and have been taxed or SORNed continuously for five years. The catch that trips up classic owners: a historic (classic) vehicle needs a current MOT certificate to assign a number, even if it is normally MOT-exempt. Book the MOT before the paperwork, not after.

That "older is fine" rule is why suffix plates are a default choice on modern cars for people who simply want their name on the back. See our guide to choosing reg plates for aged cars for how the age logic works across the other formats.

How do you buy and transfer a suffix registration?

Timings are indicative and correct as of 21 August 2026. A retained number must be renewed every 10 years — see keeping a private plate without a car and our step-by-step DVLA transfer guide. Already own a suffix plate? Use our free plate valuation.

FAQs

What is a suffix number plate?

A suffix number plate is the UK format used from February 1963 to 31 July 1983: three letters, one to three numbers and a single year letter at the end — for example BOB 1A or JAM 1S. The final letter identifies the year the registration was issued.

What years do suffix number plate letters cover?

A is 1963, B 1964, C 1965 and D 1966. E covers January to July 1967 only, then F to Y each run 1 August to 31 July, ending with Y (1 August 1982 to 31 July 1983). The letters I, O, Q, U and Z were never used.

Why does 1967 have two suffix letters?

The changeover moved from 1 January to 1 August in 1967 at the motor industry's request, to spread demand away from a January rush. E was issued only from January to July 1967 and F began on 1 August 1967, making 1967 the only year with two suffix letters.

Can I put a suffix plate on a modern car?

Yes. DVLA rules only prevent a registration making a vehicle look newer than it is, so a suffix plate can go on any vehicle registered in 1963–1983 or later, including a brand-new car. You cannot put it on a car older than the plate's year letter.

How much does a suffix number plate cost?

On Right Reg's featured plates page on 21 August 2026, suffix registrations ranged from £1,995 (JEN 19F, RAJ 32D) to £125,000 (DAV 7D), with a large choice between £3,000 and £10,000. Prices exclude VAT and the £80 DVLA transfer fee.

Are suffix plates better than prefix plates for names?

For three-letter names and initials, usually yes: the letters come first, so BEN 1Y, JAM 1S or ALF 41S read as a name immediately. Prefix plates (1983–2001) put a letter and number first, so they suit a single initial with a low number, such as A1 BEN.

Do I need an MOT to put a suffix plate on a classic car?

Yes, if the vehicle is registered as historic. GOV.UK states a historic vehicle needs a current MOT certificate before a private registration can be assigned, even if it is otherwise MOT-exempt. Arrange the MOT before submitting the application.

What happened after suffix plates ended in 1983?

From 1 August 1983 the prefix format took over, moving the year letter to the front as A123 BCD, and ran to August 2001. It was then replaced by the current two-letter, two-number, three-letter style.
