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.
What is a VIN? The VIN is the Vehicle Identification Number for your automobile or truck. This number breaks down your vehicle to illustrate such things as engine size, body style, model year, transmission type, color, etc. For vehicles newer than 1980, this is a 17 digit alphanumeric number.
