WMI
Digits 1 through 3 combined is the WMI, (World Manufacturer Identifier).

The first digit of the VIN number is the country of origin or final processing plant. For example, numbers, 1, 4 and 5 represent the U.S. 2 is Canada and the number 3 represents Mexico. The Society of Automotive Engineers are the ones who assign WMI’s to countries and manufacturers. Next is the digit that represents the manufacturer, for example, ‘G’ is for General Motors, ‘C’ can be Chrysler and ‘B’ for BMW.

The third digit combined with the first two may identify the type of vehicle, such as whether it is a truck, SUV or car. For example, a Chevrolet truck VIN would start as ‘1GC’. 1 for the US as the country of origin, G for General Motors and C for Truck.

Vehicle Descriptor
Digits 4 through 8 represent the vehicle descriptor section.

This is information such as model type, restraint types, body type, engine, and transmission.

Check Digit
Digit 9 is a check digit.

The 9th digit is like a security code, called a check digit. It is a code number/letter the manufacturer generates to verify authenticity of the whole number.

Vehicle Identification Section (VIS)
Digits 10 through 17 is the Vehicle Identifier Section.

The 10th digit is the model year. This table below is a good quick guide to years. So if the 10th digit is a ‘D’ this means the vehicle is a 2013 model.
