Decoding the VIN: checking a vehicle's history

The VIN (Vehicle Identification Number) is each vehicle's unique 17-character fingerprint. Decoding it confirms the car matches the listing.

Where to find the VIN

  • Bottom of the windscreen, driver's side
  • Driver's door pillar
  • Registration certificate

What it reveals

Make, year, factory, engine and often the original equipment. Cross-checking this manufacturer data with the listing quickly exposes any inconsistency.
