What a free reg check reveals
A registration number is the key to a vehicle's official record. Type it in and you can confirm what the vehicle is, how old it is, and whether it's currently legal to use, without seeing the paperwork. A free PlateWise reg check shows:
- make and model, colour, fuel type and engine size
- year of manufacture and the month it was first registered
- tax status and the date tax is due
- MOT status, expiry date and the complete MOT test history
- CO₂ emissions and Euro status, where recorded
- an estimate of ULEZ compliance
- whether the vehicle has been marked for export, and when the last V5C was issued
That last date is more useful than it sounds. A V5C issued last week on a car being sold by someone who claims to have owned it for years is worth a question.
Using a reg checker before you buy
A reg checker matches a number plate to the vehicle record. Run a car reg check to confirm the make, model and colour match the car in front of you: it's the simplest way to check plate details against a cloned car. A car reg check UK-wide works on current, prefix, suffix and private plates. To check car number plate age, use the age identifier guide below.
How UK number plates work
British registrations follow several formats, and each one tells you something different. Knowing them helps you spot an advert that doesn't add up.
| Format | Example | In use | What it tells you |
|---|---|---|---|
| Current | AB24 CDE | September 2001 to today | Region of first registration and the six-month period it was registered |
| Prefix | A123 BCD | 1983 to 2001 | The first letter shows the registration year |
| Suffix | ABC 123D | 1963 to 1983 | The last letter shows the registration year |
| Dateless | ABC 123 | Before 1963 | No age information, so often sold as a private plate |
| Northern Ireland | ABZ 1234 | Since 1903 | Contains I or Z, with no age identifier |
Reading a current-style plate
Take AB24 CDE as an example:
- AB is the memory tag. The first letter shows the region where the vehicle was first registered (for example, A for Anglia), and the second relates to a local office.
- 24 is the age identifier, showing when it was first registered.
- CDE are random letters that make the registration unique.
The age identifier explained
New plates are released twice a year. In March the identifier is the last two digits of the year. In September, 50 is added. So a “24” plate was first registered between March and August 2024, and a “74” plate between September 2024 and February 2025.
| Year | March to August | September to February |
|---|---|---|
| 2021 | 21 | 71 |
| 2022 | 22 | 72 |
| 2023 | 23 | 73 |
| 2024 | 24 | 74 |
| 2025 | 25 | 75 |
| 2026 | 26 | 76 |
If an advert describes a car as a 2023 model but the plate shows 19, either it carries a private registration or something is wrong. Our check shows the real first registration date either way.
What the first letter means
The first letter of a current-style plate shows the region where the vehicle was first registered. Some well-known examples:
| First letter | Region |
|---|---|
| A | Anglia |
| B | Birmingham |
| C | Cymru (Wales) |
| L | London |
| M | Manchester and Merseyside |
| N | North (Newcastle and Stockton) |
| S | Scotland |
| Y | Yorkshire |
Dealers often register cars in bulk, so the region reflects where the car was first registered, not necessarily where its owners lived.
Prefix plates: reading the year letter
On prefix plates, used from 1983 to 2001, the first letter shows the year. Until 1998 the letter changed each August. From 1999 it changed every March and September, which is how the current twice-yearly system began. A few of the later letters:
- R: August 1997 to July 1998
- S: August 1998 to February 1999
- T: March to August 1999
- V: September 1999 to February 2000
- W: March to August 2000
- X: September 2000 to February 2001
- Y: March to August 2001
Letters that are easily confused with numbers, such as I and O, were never used as year letters. If you see an older car on a prefix plate, the reg check confirms whether the year letter matches the record.
Using a number plate check to spot cloned cars
A cloned car wears the registration of a genuine, legally registered vehicle of the same make and model, often to hide that it's stolen or to dodge fines. Because the plate is real, a number plate check on its own will come back looking normal. The trick is to compare the record with the car in front of you.
- Colour, engine and fuel should match the record exactly. A diesel record on a petrol car is a serious warning.
- The VIN stamped on the car (usually at the base of the windscreen and on a door pillar) must match the V5C. Never buy without checking.
- The V5C itself should have a watermark and shouldn't look photocopied. The address should be where you're viewing the car.
- The MOT history should fit the car's condition. A car with a newly fitted interior but years of advisories for torn seats doesn't make sense.
If you're the victim of cloning
Car registration check for private plates
Private (cherished) registrations can be moved between vehicles. When that happens, the vehicle's record moves with it, so a reg check on a private plate still shows the right car. There are rules to stop abuse: you can't put a registration on a vehicle that would make it look newer than it is, although an older-looking number such as a dateless plate can go on any vehicle.
If a car has recently had a private plate removed, the MOT history follows the vehicle rather than the plate. When records seem to stop abruptly, ask the seller whether the registration has changed.
Legal number plate rules
Plates must be made by a registered supplier and meet the current British Standard. Characters must use the standard font and spacing, in black on a white (front) or yellow (rear) reflective background. Since 2021 the optional national identifier is “UK” rather than “GB”, and zero-emission vehicles can display a green flash on the left.
Altering the spacing, using stylised fonts or adding screws that change how characters read can mean a fine of up to £1,000. Incorrectly displayed plates are also an MOT failure, so a quick look at the plates during a viewing tells you something about the owner.
What a reg check can't tell you
The DVLA and DVSA hold a lot, but not everything. A free car registration check won't show the keeper's name or address, which are protected by data protection law. It won't show whether a finance company still owns part of the car, or whether an insurer once declared it a write-off. Those records sit with private companies, which is why paid history checks exist.
It also can't tell you how the car drives. Use the reg check to rule cars out quickly, then judge the ones that remain on a test drive, the paperwork and, where it matters, an independent inspection. The MOT advisories on record tell you where to look first.
