The first three characters indicate the country of assembly. Chevies are assembled in the United States, Canada and Mexico so the VIN begins with a 1, 2 or 3, respectively. The second character is G for General Motors. The third position varies.
The fourth position indicates the vehicle brake system and body style. The fifth and sixth characters indicate the chassis series. For example, VH indicates a Traverse ½ ton LTZ.
The seventh character is the restraint code. For example, an E indicates active seat belts and airbags in all seating rows.
Position 8 indicates the engine type. For example, D stands for a 3.6L V6 engine.
The ninth character is a unique digit check and validates the entire VIN.
Position 10 indicates model year and is represented by a letter. For example, an A indicates the vehicle was built in 2010.
The eleventh character identifies the manufacturing plant. For example, S indicates the vehicle was made in the Springhill, Tenn. plant.
The last six positions are a sequential production number.
