VIN Number Decoded

A VIN isn't random. The first three letters tell you the country and manufacturer; the tenth is the model year. Here's the full map.

A VIN is 17 characters, and every position means something specific. Here's the full map.

Positions 1 to 3: manufacturer

First character is country (1, 4, or 5 for USA, J for Japan, W for Germany). Characters two and three narrow to manufacturer and region.

Positions 4 to 8: vehicle attributes

Manufacturer-specific. Encodes model, body style, engine, transmission, and restraint system. Decoding needs the manufacturer's key. Our free VIN decoder handles the common ones.

Position 9: check digit

A single character that validates the rest mathematically. If any other position was tampered with, this stops matching.

Position 10: model year

A letter or number. A is 1980 or 2010, B is 1981 or 2011, and so on. Cycle repeats every 30 years.

Position 11: assembly plant

One character for the plant where the car was built.

Positions 12 to 17: serial number

The vehicle's sequential number at that plant for that model year.
