GM VIN decoder

Enter a GM VIN to get its year, model, trim, engine and assembly plant from NHTSA. GM VINs start with one of 110 manufacturer codes across 7 countries; the first character tells you where it was built (1, 2, 3, 4, 5, 6, A, J, K, L, W).

GM models and model years

Checking that a decoded year makes sense? These are the GM models the EPA has rated since 2000, 40 of them still on sale for 2025 or later. A VIN whose 10th character points to a year outside a model's range is worth a second look.
