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 stands for Vehicle Identification Number. This is the real long number usually found on the drivers side just below the windshield. It has letters and numbers in it. The engine number is stamped / engraved somewhere on the engine block.
