Every Chevrolet Blazer (2019–2024) carries a 17-character VIN that begins with the 3GN WMI. The Blazer is a gas SUV; this page shows what each character of a Chevrolet Blazer VIN means and gives 4 checksum-valid sample VINs you can drop straight into test fixtures. Synthetic — not real: no scraping, no real-owner data. The generator below is pre-filtered to the Blazer.
Each sample below is built from the real 3GN WMI and the Blazer's descriptor, so it decodes to a Chevrolet Blazer of the right model year:

Worked on the sample 3GNKBHRS8K6983673 — a 2019 Chevrolet Blazer:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 3GN | Marks the VIN as Chevrolet, built in Mexico |
| 4–8 | VDS | KBHRS | Descriptor for the Blazer — SUV body, gas powertrain |
| 9 | Check digit | 8 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | K | Code K = 2019 |
| 11 | Plant | 6 | Assembly-plant code |
| 12–17 | Serial | 983673 | Sequential production number |
Positions 1–3 of every Chevrolet Blazer VIN read 3GN — the World Manufacturer Identifier that marks the vehicle as Chevrolet, assembled in Mexico (North America). After the WMI, positions 4–8 (KBHRS in our seed) describe the Blazer itself; see the full 17-digit format.
Position 10 encodes the model year. For the Blazer, 2019 is code K and 2024 is code R. See the 2024 year code or the check-digit math.

A Chevrolet Blazer VIN is 17 characters starting with the 3GN WMI, for example 3GNKBHRS8K6983673. Positions 4–8 describe the Blazer, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: 3GN is the Chevrolet WMI, positions 4–8 are the Blazer descriptor, position 9 verifies the VIN via a mod-11 checksum, position 10 gives the year, position 11 the plant, and 12–17 the serial. Paste any VIN into the decoder to do it automatically.
The Blazer in our seed uses the 3GN WMI (Mexico). Any VIN beginning with 3GN decodes to Chevrolet.
No. They are synthetically generated but checksum-valid, use the real Chevrolet 3GN WMI, and carry the Blazer's descriptor and a valid year code — so a decoder returns a Chevrolet Blazer. No real vehicle's VIN is used.
