What a VIN actually tells you

A VIN (Vehicle Identification Number) is a 17-character code stamped on the vehicle and printed on the registration document. It is divided into three parts: the WMI (world manufacturer, positions 1-3), the VDS (vehicle descriptor, positions 4-9) and the VIS (vehicle identifier, positions 10-17, where position 10 is the model year and position 11 the plant).

  • Positions 1-3: country and manufacturer (WMI)
  • Positions 4-9: model, body and engine descriptor (VDS)
  • Position 9: check digit (North America)
  • Position 10: model year
  • Position 11: assembly plant
  • Positions 12-17: production serial number

Decoding only works if you read the whole VIN

The last six digits look unique, but the meaning (model, engine, body) is carried by the middle of the VIN. That is why a decoder needs the full 17 characters - a partial code gives partial answers.

  • The letters I, O and Q are never used (they look like 1 and 0)
  • US-market VINs use a check digit that can be validated
  • European VINs often omit the check digit
  • The model year is a code, not always the first registration year

From VIN to the right tool

Once decoded, use the make, model and year with the oil-specs, tire, battery, OBD protocol and service book tools. You can save the vehicle as "My vehicle" - it stays on your device and speeds up every later lookup.

FAQ

On the vehicle registration document (V5C in the UK, carte grise in France), at the base of the windshield on the driver side, on the driver door jamb sticker, and often under the hood.
Manufacturers only submit the data they choose. The NHTSA database is very complete for US vehicles and less detailed for older or non-US models - an empty field does not mean the VIN is wrong.
Yes. The lookup is sent to the public NHTSA vPIC service and cached on our server. AutoTools does not store your VIN or link it to you.
Sometimes (Series and Trim fields), but not always. Brands often encode trim in codes that are not publicly documented. Use the decoded body, engine and fuel type as the reliable parts.
