What is a VIN?

A Vehicle Identification Number (VIN) is a unique 17-character code assigned to every motor vehicle sold in the United States since 1981. It serves as the vehicle's fingerprint: no two vehicles in operation have the same VIN. The format is standardized by ISO 3779 and enforced in the U.S. by 49 CFR Part 565.

Excluded characters

The letters I, O, and Q are never used in VINs to avoid confusion with the numbers 1, 0, and 9. If your VIN contains any of these letters, double-check the source document.
