How to read a Chevrolet Trailblazer VIN
Here is a real 2026 Chevrolet Trailblazer VIN from our database, split into its parts:
VIN KL79MUSL8TB298393 — decoded free on its own report page.
| Position | Section | What it tells you |
|---|---|---|

| 4–8 | VDS | Vehicle Descriptor Section — body style, engine, restraint system, series. |
| 9 | Check digit | A calculated digit that validates the whole VIN. Wrong digit = wrong VIN. |

Where Chevrolet Trailblazer VINs say the car was built
The first three characters are the World Manufacturer Identifier. Across 119 Chevrolet Trailblazer VINs we have on file, these are the codes that actually show up — and the plants behind them:
| WMI | Built in | Vehicle type | VINs on file | Share |
|---|---|---|---|---|
| KL7 | South Korea | — | 83 | |
| 1GN | United States | — | 36 |
Country and vehicle type come from the NHTSA manufacturer registry. Share is measured across VINs decoded on ForCar, not production volume.

|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tire pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |
