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? VIN (Vehicle Identification Number) is a unique universal serial number issued to every vehicle by the manufacturer. Within the 17-digit number are codes that indicate the vehicle's make and model, the factory where the vehicle was manufactured, a serial number and information about optional equipment.
