Chevrolet VIN Check

Every Chevrolet vehicle manufactured for the North American market since 1981 carries a standardized 17-character Vehicle Identification Number (VIN) regulated by NHTSA under FMVSS 565 and ISO 3779. This code is unique to each vehicle and encodes the country of assembly, manufacturer identity, model attributes, engine configuration, model year, assembly plant, and production sequence number. Decoding a Chevrolet VIN helps you verify a used-vehicle listing, confirm the correct parts and service history, check for open recalls, and detect potential title fraud.

Chevrolet uses manufacturer-specific encoding in the Vehicle Descriptor Section (positions 4–8). Position 4 typically identifies the model line — for example, popular Chevrolet models include Silverado, Equinox, Tahoe, Malibu, Traverse, Colorado, Corvette, Blazer. Position 8 usually encodes the engine type. Position 9 is a mathematical check digit that detects typos and many forms of VIN tampering. Position 10 encodes the model year, and position 11 identifies the assembly plant. 1G1 is the standard WMI for U.S.-built Chevrolet cars; 1GC is used for Chevrolet trucks including Silverado.

Chevrolet was founded by Louis Chevrolet and William C. Durant in 1911 and became GM's volume brand. The Bowtie emblem is one of the most recognized automotive brands worldwide. Corvette has been built exclusively at Bowling Green, Kentucky since 1981.

To read a Chevrolet VIN manually, start with the WMI (positions 1–3) to confirm the manufacturer and country of origin. For Chevrolet, the WMI prefixes in our database include 1G1, 1GC, 2G1, 3G1 and others depending on where the vehicle was built.

Position 4 encodes the Vehicle Line. Common values include A=Passenger car, B=Passenger car, C=Truck, D=Multi-purpose, E=Incomplete vehicle, F=SUV. Position 5 encodes trim or series level. Position 8 encodes the engine (A=2.0L Turbo 4-cyl, B=2.5L 4-cyl, C=3.6L V6, D=5.3L V8, E=6.2L V8). Position 9 is the check digit — our decoder validates it automatically using the ISO 3779 weighted-sum algorithm. Position 10 is the model year (see our year-code reference), and position 11 is the assembly plant (A=Lansing, MI, B=Bowling Green, KY, C=Detroit, MI, D=Lordstown, OH, E=Fort Wayne, IN). Positions 12–17 are the unique serial number for that vehicle.

Because Chevrolet may change VDS encoding between model years, treat decoded attributes as informational. Always confirm critical details (engine, trim, drivetrain) against the window sticker, build sheet, or dealer records.
