What Your Registration Plate Actually Tells You About Your Car

The two letters at the start of a UK number plate tell you where the car was first registered. The two numbers in the middle tell you roughly when. The three random letters at the end are a unique identifier for the vehicle.

That's the surface level. What's more useful is what the registration links to in DVLA and DVSA records.

The area code

The first two letters identify the DVLA local office where the vehicle was registered. 'LD' for London, 'BF' for Birmingham, 'MA' for Manchester, and so on. This can indicate where the car was first sold, useful context if you're buying used and the seller's location seems inconsistent with the plate.

The age identifier

The two numbers encode the registration period. Plates issued March, August carry the year (e.g., 24 for 2024). Plates issued September, February add 50 (e.g., 74 for September 2024). So a plate reading '24' was registered between March and August 2024. A plate reading '74' was registered between September 2024 and February 2025.

What the DVLA can tell you from a reg plate

Run a registration plate through the DVLA's Vehicle Enquiry Service and you'll get:

• Make, model, and colour
• Engine size and fuel type
• Date of first registration
• Current MOT expiry date
• Road tax (VED) status
• Whether the car has been reported as stolen or written off

This is publicly available via gov.uk, useful when buying a used car and wanting a quick check before committing to a test drive.

What the DVSA MOT history shows

Separately, the DVSA MOT history service (also free, also via gov.uk) gives you the full MOT record for any vehicle, pass/fail outcomes, advisory notices, and mileage at each test. This mileage history is one of the most useful checks when buying used: it quickly reveals whether the odometer reading is consistent with the car's recorded history.

There's something reassuring about knowing that the string of characters on your number plate connects to a complete public record of your vehicle. It's the kind of transparency that makes buying and selling cars more honest, and managing the one you own considerably easier when an app knows how to read it.
