Vehicle Identification Numbers (VINs) Vehicle Identification Numbers are unique codes given to each on-road vehicle in the United States. From 1981, each new car is given a standardized 17-digit code, which includes a serial number. Older cars may have VINs too, although they will not follow the standardized formula.
The VIN (Vehicle Identification Number) is a serial number used to identify an individual vehicle. The VIN for each vehicle is unique. The 10th character in the 17-character VIN represents the vehicle model-year. This standard applies to vehicles built in or after 1981. Before 1981, the VIN format was not standardized and varied by manufacturer. Note: VINs do not include the letters I (i), O (o), Q (q), U (u) or Z (z), or the number 0, so that they will not be confused with similar looking numbers/letters.
