Every Chevrolet Colorado (2017–2023) carries a 17-character VIN that begins with the 1GC WMI. The Colorado is a gas truck; this page shows what each character of a Chevrolet Colorado 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 Colorado.
Each sample below is built from the real 1GC WMI and the Colorado's descriptor, so it decodes to a Chevrolet Colorado of the right model year:

Worked on the sample 1GCGTCEN1H1126501 — a 2017 Chevrolet Colorado:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 1GC | Marks the VIN as Chevrolet, built in United States |
| 4–8 | VDS | GTCEN | Descriptor for the Colorado — truck body, gas powertrain |
| 9 | Check digit | 1 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | H | Code H = 2017 |
| 11 | Plant | 1 | Assembly-plant code |
| 12–17 | Serial | 126501 | Sequential production number |
Positions 1–3 of every Chevrolet Colorado VIN read 1GC — the World Manufacturer Identifier that marks the vehicle as Chevrolet, assembled in United States (North America). After the WMI, positions 4–8 (GTCEN in our seed) describe the Colorado itself; see the full 17-digit format.
Position 10 encodes the model year. For the Colorado, 2017 is code H and 2023 is code P. See the 2023 year code or the check-digit math.

A Chevrolet Colorado VIN is 17 characters starting with the 1GC WMI, for example 1GCGTCEN1H1126501. Positions 4–8 describe the Colorado, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: 1GC is the Chevrolet WMI, positions 4–8 are the Colorado 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 Colorado in our seed uses the 1GC WMI (United States). Any VIN beginning with 1GC decodes to Chevrolet.
No. They are synthetically generated but checksum-valid, use the real Chevrolet 1GC WMI, and carry the Colorado's descriptor and a valid year code — so a decoder returns a Chevrolet Colorado. No real vehicle's VIN is used.
