Number Plate Year Chart: Age Identifiers Explained

What Is A Number Plate Year Chart?

A number plate year chart is a lookup of age identifiers against registration periods. Because the system has followed one rule since September 2001, a number plate by year can be worked out in seconds without a table.

Why the rule beats a long chart

A chart has to be extended every six months and can contain typing errors. The rule stays correct forever, so it is the safer thing to remember.

What the digits are officially called

The DVLA refers to them as the age identifier. They sit directly after the two-letter memory tag and before the three random letters.

What Year Is My Number Plate?

To answer what year is my number plate, find the two digits and apply one of two sums: if they are 50 or below, add 2000; if they are 51 or above, subtract 50 and then add 2000.

The March to August half

Digits equal to the year apply from 1 March until the end of August. A plate reading 19 therefore belongs to a vehicle first registered between March and August 2019.

The September to February half

Digits equal to the year plus 50 apply from 1 September until the end of the following February. A plate reading 69 therefore means September 2019 to February 2020.

Age Identifier Chart: Worked Examples

How to extend the pattern yourself

Pick the next March and use the year; pick the following September and add 50. The identifier for any later year follows the same logic.

Why it starts at 51

The first September under the current system was in 2001, so the first plate with a plus-50 identifier was 51. The first March identifier after that was 02, for 2002.

Why Do The Plates Change In March And September?

The plates change twice a year to spread new-car registrations across the calendar rather than concentrating them in one month. Dealers still see a spike each time, which is why new plate day is so busy.

• March is the traditional spring surge.
• September is the second, smaller surge.
• Many buyers choose a car with the latest identifier for resale value.

For the specific dates, see when does the 25 plate come out and when do 75 plates come out.

Does The Plate Give The Exact Date Or Month?

No. The number plate age identifier gives a six-month window, so a reg plate year is a range rather than a day.

Where to find the first registration month

The DVLA Vehicle Enquiry Service shows the month and year of first registration for many vehicles, and the V5C logbook records the date of first registration. The free number plate check shows the year of manufacture and first registration drawn from official records.

How MOT history helps

An MOT history record lists tests and recorded odometer readings that follow a vehicle's real age, which is a useful cross-check on the identifier.

What Do Registration Year Letters Mean On Older Plates?

Before September 2001 the year was shown by a single letter, not by two digits, so registration year letters apply only to prefix and suffix plates.

Prefix letters, 1983 to 2001

A prefix plate such as A123 BCD starts with the year letter. The letters began at A in 1983 and ran through to Y in 2001, with some letters skipped. From 1999 the prefix letter changed twice a year.

Suffix letters, 1963 to 1983

A suffix plate such as ABC 123A ends with the year letter, starting with A in 1963 and reaching Y in 1983. Before 1963, registrations were generally combinations without a year letter.

Dateless plates have no year at all

A dateless plate shows neither letters nor digits for a year, so it cannot give the age of a car. See dateless number plates for the formats.

How To Check A Reg Plate Age With A Lookup

A number plate year check is quickest with an official-record lookup, because it reports the year the vehicle was actually first registered.

1. Enter the registration into the free number plate check.
2. Note the year of manufacture or first registration shown.
3. Compare it with the age identifier on the plate.
4. Look at the MOT history for the first test date and mileage trend.
5. Ask the seller for the V5C logbook, which names the registered keeper and the vehicle identification number (VIN, also called the chassis number), if anything disagrees.

When The Plate And The Vehicle Do Not Match

A plate can legitimately show a different age from the vehicle's real age, so a mismatch is not always a warning sign.

• A transferred private plate can sit on a newer or older vehicle, within DVLA rules.
• A dateless cherished plate carries no age at all.
• An imported vehicle takes a new registration when it arrives, not when it was built.
• A rebuilt or kit car may carry a registration issued years after the parts were made.
• A cloned plate copies a genuine registration and is illegal.

The DVLA rule on newer-looking plates

The DVLA does not allow a number that makes a vehicle look newer than it is. Check the current conditions on GOV.UK before assigning a plate.

What to do if it looks wrong

Compare the plate with the make and model, then run a vehicle check. If the identifier says one thing and the records say another, ask the seller to explain before paying anything.

Should You Wait For A New Identifier When Buying A Car?

Waiting for a new identifier can matter to a buyer, but it is a preference rather than a rule. A car registered just before the change will often be priced differently from the same car registered just after it.

• Check whether the car was registered as new or is a nearly new used car.
• Ask when it was first registered, not just which plate it wears.
• Compare similar cars across both sides of a change date.
• Read what to look for when buying a used car before committing.

Pre-registered cars

A dealer can register a car before selling it, so the identifier may be earlier than the date you take delivery. The V5C logbook will show the first registration date.

Can The Age Identifier Be Changed On A Plate?

No. The characters on a plate must match the registration number held by the DVLA, and altering, restyling or covering them is not allowed. A plate that shows a different year from the vehicle's records is a matter for the DVLA, not for a plate maker.

• Stickers and paint used to change characters are not permitted.
• Only a registered number plate supplier may make plates.
• Suppliers must see proof of identity and entitlement to the registration number.

What Is The Current Age Identifier?

The current identifier depends on the date. From 1 March 2026 it is 26, and from 1 September 2026 it is 76; after that the next March brings 27. Check the calendar and the rule rather than a stored list.

Northern Ireland And Republic Of Ireland Plates

Northern Ireland registrations do not use the March and September age identifier at all, and Irish registrations use a year code of their own. Read Irish number plates for how that system works.

Motorbikes, Vans And Electric Vehicles

Every road vehicle in Great Britain uses the same age identifier system, including motorcycles, vans and electric vehicles. The green flash on a zero-emission vehicle does not change the identifier.

Common Mistakes When Reading The Year

• Treating 75 as 1975. It means September 2025 to February 2026.
• Forgetting that digits above 50 need 50 subtracted.
• Assuming the exact month from a six-month window.
• Treating a short private plate as evidence of age.
• Ignoring that the first registration, not the build date, drives the identifier.

Does The Age Identifier Affect Value Or Tax?

The identifier does not set a vehicle's price by itself, but the first registration date often affects vehicle tax rules and the MOT due date, so it is worth knowing. The current rules are on GOV.UK, and when does my MOT run out explains how the due date is worked out.

Quick Reference: Reading The Digits

• 50 or below: add 2000, March to August.
• 51 or above: subtract 50, add 2000, September to the following February.
• Prefix letter: era from 1983 to 2001.
• Suffix letter: era from 1963 to 1983.
• No year letter: a dateless plate.
