Where to Find Your VIN Number (on the Title, V5C and the Car)

The VIN is your car’s fingerprint. Whether you’re checking a listing before buying, ordering the right part, or pulling a vehicle history report, the first step is always the same: find it. Here’s exactly where it hides, on the paperwork and on the car.

On the paperwork

In the US, the 17-character VIN is printed on the vehicle title and on the registration document. It’s the number that ties the car to its legal history — ownership, title brands, and any total-loss record.

In the UK, the VIN is on the V5C logbook (the registration certificate), in the vehicle details section on the front page. It’s labelled “VIN / Chassis number”.

This number is unique worldwide: no two vehicles share a VIN. That’s what makes it possible to trace a car’s entire history from a single string of characters.

On the car: four places to look

If you’re inspecting a car without the paperwork in front of you — for example on a pre-purchase viewing — the VIN is physically stamped or applied in several spots:

1. Base of the windshield, driver’s side — visible from outside through a small metal plate. The fastest one to check.
2. Driver’s door jamb — a manufacturer sticker, visible with the door open, that also lists tyre pressures and weights.
3. In the engine bay — stamped on the chassis or firewall, depending on the model.
4. Under the passenger carpet or in the trunk, near the spare wheel, on some makes.

The smart move: compare the VIN on the document with the one on the windshield and the door jamb. If they don’t match, be careful — it can signal an accident-damaged and “cloned” car, or a stolen one.

VIN, chassis number, frame number: the same code

These all mean the same thing. “VIN” (Vehicle Identification Number) is the international name; “chassis number” and “frame number” are common alternatives. A standardised VIN is always 17 characters, without the letters I, O and Q.

Those 17 characters aren’t random: the first 3 identify the manufacturer and country (WMI), the next 6 describe the vehicle — body, engine, trim (VDS) — and the last 8 are the serial number and model year (VIS).

Decode the VIN for free

Once you’ve found the number, you can decode it for free to read what it holds. Enter the 17 characters into Automano’s free VIN decoder and you’ll get the make, model, exact trim, year, engine and a value estimate in seconds — no sign-up, no email.

This is especially useful for pinning down the trim of a used car: two cars that look identical can carry very different equipment and value, and the VIN settles it.

Why check the VIN before you buy

The VIN isn’t just admin — it’s the key to the car’s identity. From it, a report confirms the exact factory specs and the manufacturer’s recalls; on UK cars, adding the reg plate also brings the DVSA MOT history with the mileage recorded at every test. For accident and import history, the free official registries of each country are the place to look — each covers the vehicles registered on its own soil.
