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 vehicle identification number (VIN) is a 17-digit number that is unique to your vehicle. All cars and light trucks built after 1981 have a VIN. The VIN can be found on the VIN plate located on the driver's side of the dashboard just below the windshield. The VIN can also be found on the driver-side doorframe placard, as well as on documents related to the vehicle's registration, title and insurance.
