A VIN (Vehicle Identification Number) is a 17-character code unique to a specific vehicle — think of it as a chassis fingerprint. Before you finance or buy a used van, knowing how to find and sanity-check one is a genuinely useful five-minute habit.
Where to find it
- The V5C logbook, section D.2.
- A metal plate riveted to the chassis, often visible in the engine bay or door sill.
- Stamped into the base of the windscreen, visible from outside the vehicle.
- Sometimes printed on a sticker inside the driver's door frame, alongside tyre pressure info.
What the characters mean, roughly
The first three characters are the World Manufacturer Identifier (who made it and where), the next six describe the vehicle's features and model, and the final eight (including a check digit for some regions) identify the individual vehicle and its production sequence. You don't need to decode it manually — but you should confirm it's 17 characters and never contains the letters I, O or Q, which are excluded to avoid confusion with 1 and 0.
Cross-check it against the vehicle and paperwork
Before you commit to a purchase, physically compare the VIN on the vehicle itself to the VIN on the V5C logbook and any finance/insurance paperwork. A mismatch is a serious red flag and grounds to walk away.

Format check vs full history check
A format check (like ours) only confirms the VIN is well-formed — it says nothing about the vehicle's actual history. For that, you need a paid HPI/finance check that queries outstanding finance, write-off status, mileage and stolen markers. See our full HPI check guide for what to run before you buy.
