Platform Codes

GM used a lettered system of automobile platform codes for three decades. These letters were used as the fourth position of the VIN. Though today's GM platforms use Greek characters, they are still encoded with Latin characters in the fourth position. Position five encodes the specific model and trim level of the vehicle.

Body Style Codes

The Body type is specified as character six of the American GM VIN for passenger cars.

American Restraint Types

The restraint type is specified as character seven of the American GM VIN for passenger cars.

American Engine Codes

GM encodes the engine type in character 8 of the VIN.

Check Digit

The check digit is used to validate that the VIN is a correct and legitimate to the vehicle.

Model Year

One consistent element of the VIS is the 10th digit, which is required worldwide to encode the model year of the vehicle. Besides the three letters that are not allowed in the VIN itself (I, O and Q), the letters U and Z and the digit 0 are not used for the model year code. Note that the year code is the model year for the vehicle.

Plant Code/ Factory ID

Another consistently used element (which is compulsory in North America) is the use of the 11th character to encode the factory of manufacture of the vehicle. Although each manufacturer has its own set of plant codes, the location in the VIN is standardized.

Sequential Number

The final six digits indicate how far along into a given production run that the vehicle was built but, because some companies make a lot of a certain model, this isn't necessarily a number. In the case of our Mustang, the digit is a number: 113456.
