The 17-digit vehicle identification number (VIN) on a Chevrolet vehicle stands for several key aspects of the car's manufacture, including body style, chassis, series, engine type, model year and plant location, according to General Motors' official VIN information page. If a consumer has a VIN, he can input the number into the Chevrolet VIN decoder to find out more details about a particular vehicle.
For Chevrolet trucks, the first three positions of the VIN designate the World Manufacturers Identifier (WMI). The fourth position indicates the body style, the fifth describes the chassis, and the sixth position designates the series. The seventh position of the VIN is for the restraint system, the eighth indicates the engine type, and the ninth numeral is the check digit. Position 10 is the model year, and 11 indicates the plant location. The final six numerals of a Chevrolet's VIN are the sequence number, which is the order of the type of vehicle as it goes off the assembly line.
Each automobile manufactured worldwide since 1981 has a unique VIN that is not duplicated anywhere else, according to Edmonds. These identification numbers go back to 1954 on American models, but the serial digits were not standardized until later. The middle part of the VIN is known as the vehicle descriptor section. Digits 10 through 17 indicate the vehicle indentifier section.
