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.
VIN is an acronym for vehicle identification number. It is a serial number composed of numbers and letters. Each vehicle has a unique identification number that can be used by the Department of Motor Vehicles -- aka, the DMV-- to identify cars and other motor vehicles. The DMV is a government agency that handles regulations on land vehicles.
