A vehicle identification number (VIN) is a unique code, including a serial number, used by the automotive industry to identify individual motor vehicles, towed vehicles, motorcycles, scooters and mopeds, as defined in ISO 3779 (content and structure) and ISO 4030 (location and attachment).
VINs were first used in 1954 in the United States. From 1954 to 1981, there was no accepted standard for these numbers, so different manufacturers used different formats.
In 1954, at the request of the US government, the US auto manufacturers and the Automobile Manufacturers Association were involved in the creation of the new, standardized vehicle identification numbering system named the Vehicle Identification Number (VIN) with an agreed upon digit sequence and concealed chassis markings of this VIN. Up to that time, states used the engine number to register and title cars
