Every Chevrolet Tahoe (2021–2024) carries a 17-character VIN that begins with the 1GN WMI. The Tahoe is a gas SUV; this page shows what each character of a Chevrolet Tahoe 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 Tahoe.
Each sample below is built from the real 1GN WMI and the Tahoe's descriptor, so it decodes to a Chevrolet Tahoe of the right model year:

Worked on the sample 1GNSKPKD1MR357000 — a 2021 Chevrolet Tahoe:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 1GN | Marks the VIN as Chevrolet, built in United States |
| 4–8 | VDS | SKPKD | Descriptor for the Tahoe — SUV body, gas powertrain |
| 9 | Check digit | 1 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | M | Code M = 2021 |
| 11 | Plant | R | Assembly-plant code |
| 12–17 | Serial | 357000 | Sequential production number |
Positions 1–3 of every Chevrolet Tahoe VIN read 1GN — the World Manufacturer Identifier that marks the vehicle as Chevrolet, assembled in United States (North America). After the WMI, positions 4–8 (SKPKD in our seed) describe the Tahoe itself; see the full 17-digit format.
Position 10 encodes the model year. For the Tahoe, 2021 is code M and 2024 is code R. See the 2024 year code or the check-digit math.

A Chevrolet Tahoe VIN is 17 characters starting with the 1GN WMI, for example 1GNSKPKD1MR357000. Positions 4–8 describe the Tahoe, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: 1GN is the Chevrolet WMI, positions 4–8 are the Tahoe 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 Tahoe in our seed uses the 1GN WMI (United States). Any VIN beginning with 1GN decodes to Chevrolet.
No. They are synthetically generated but checksum-valid, use the real Chevrolet 1GN WMI, and carry the Tahoe's descriptor and a valid year code — so a decoder returns a Chevrolet Tahoe. No real vehicle's VIN is used.
