Here is the 2021 GM VIN decoder. Use this to check a Trailblazer's VIN to ensure a dealer is listing a car for sale correctly. Confirm that you receive the car you ordered.

Great find @Maize! I'm going to be sure to use this while I'm looking for a Trailblazer!

Some manufacturers, such as Renault, Mercedes-Benz, Toyota, do not indicate the model year in the VIN code at all. The year of manufacture is indicated on the plate on the body. I once heard that there is a good vin decoder on Free VIN Decoder Online | Decode any VIN - Vingurus and he himself used this service several times for free.
