Number Plate Check - What Your UK Reg Means (Free Decoder)

How to read a current UK number plate

Every AB12 CDE plate is three pieces of information in a row.

The area code

The first two letters are the DVLA "memory tag". The first letter is the region (L for London, S for Scotland, M for Manchester) and the second narrows it to the office that first issued the mark.

The age identifier

The two numbers date the plate to a six-month window. 12 means March–August 2012; add 50 for the autumn batch, so 62 is September 2012–February 2013. That's the reg's release period, not necessarily the car's build date.

The random letters

The last three letters mean nothing; they're issued in sequence to keep every combination unique. The only rule is that certain letters are skipped where they'd be easy to misread.

What the area code really tells you

People love reading a story into a number plate, and the area code is the part that carries one. When a car is first registered, the DVLA hands out a mark from the batch held at a local office, so the two opening letters point back to a corner of the country: Anglia, the Garden of England, Severn Valley, and so on. It's a genuinely nice bit of trivia, and occasionally a useful sanity check. You can browse every area code by region to see which office handed out a given tag.

What it is not is a tracker. A registration can be transferred to a new owner, moved onto a different vehicle, or simply follow a car that's been driven the length of the country twice over. So a Glasgow tag on a car for sale in Kent tells you where the plate started life, not where the vehicle has spent it. If where a car has been actually matters to you, the record that counts is its MOT test history: testing stations are dotted across the country, and the mileage trail within it is far harder to fake than a plate.

The other half of the code, the age identifier, is the bit worth checking against the advert. If a listing calls a car a 2015 model but the plate reads 64 or 15, that lines up. If the numbers don't match the year quoted, it's not automatically dodgy (a plate can be newer than the car after a transfer), but it's a question worth asking. Our guide to UK plate formats walks through every scheme in full, and the V5C logbook guide explains how a transferred plate shows up on the paperwork.

Age identifier quick reference

The two digits map to a six-month registration window: March releases use the year itself, September releases add 50. The recent codes, newest first:

Plate code	First registered
26	March – August 2026
75	September 2025 – February 2026
25	March – August 2025
74	September 2024 – February 2025
24	March – August 2024
73	September 2023 – February 2024
23	March – August 2023
72	September 2022 – February 2023
22	March – August 2022
71	September 2021 – February 2022
21	March – August 2021

The same two rules run all the way back to September 2001, so any current-style plate decodes the same way: 04 is spring 2004, 54 is the autumn batch that followed it.

When you've decoded the plate and you're serious about the car behind it, the full £5.00 report takes over: it looks up the actual vehicle and lays out the whole record (every MOT since 2005, the mileage history, tax position, registered details and spec, with a photo) so you're buying on facts, not a hunch about the plate.

Number plate check: common questions

What does my number plate tell me?

A current UK plate (like AB12 CDE) packs in three things: the first two letters are a DVLA area code showing where the mark was first issued, the two digits are the age identifier for the six-month period it dates from, and the last three letters are random. Older prefix and suffix plates carry the year in a single letter instead.

Does the area code show where the car is now?

No, and this trips a lot of people up. The area code records where the registration was first issued, not where the vehicle lives today. Plates get transferred between owners and regions all the time, so a "Manchester" tag on a car parked in Cornwall is perfectly normal.

Why does my plate have no area code?

Only current-style plates (September 2001 onward) use the two-letter area code. Prefix, suffix, dateless and Northern Ireland plates were issued under older schemes, so the decoder shows their format and age but no region.

Is this the same as a full vehicle check?

No. This reads the plate itself and costs nothing. It can't tell you the car's MOT history, mileage record, tax status or spec; for that you need the actual vehicle record, which is what the £5 report pulls together.
