Every Jeep Gladiator (2020–2024) carries a 17-character VIN that begins with the 1C6 WMI. The Gladiator is a gas truck; this page shows what each character of a Jeep Gladiator 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 Gladiator.
Each sample below is built from the real 1C6 WMI and the Gladiator's descriptor, so it decodes to a Jeep Gladiator of the right model year:

Worked on the sample 1C6JJTAG5LL278014 — a 2020 Jeep Gladiator:
| Position | Section | Value | What it tells you |
|---|---|---|---|
| 1–3 | WMI | 1C6 | Marks the VIN as Jeep, built in United States |
| 4–8 | VDS | JJTAG | Descriptor for the Gladiator — truck body, gas powertrain |
| 9 | Check digit | 5 | Mod-11 checksum over the other 16 characters |
| 10 | Model year | L | Code L = 2020 |
| 11 | Plant | L | Assembly-plant code |
| 12–17 | Serial | 278014 | Sequential production number |
Positions 1–3 of every Jeep Gladiator VIN read 1C6 — the World Manufacturer Identifier that marks the vehicle as Jeep, assembled in United States (North America). After the WMI, positions 4–8 (JJTAG in our seed) describe the Gladiator itself; see the full 17-digit format.
Position 10 encodes the model year. For the Gladiator, 2020 is code L and 2024 is code R. See the 2024 year code or the check-digit math.

A Jeep Gladiator VIN is 17 characters starting with the 1C6 WMI, for example 1C6JJTAG5LL278014. Positions 4–8 describe the Gladiator, position 9 is the check digit, position 10 is the model year, and 12–17 are the serial number.
Read it left to right: 1C6 is the Jeep WMI, positions 4–8 are the Gladiator 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 Gladiator in our seed uses the 1C6 WMI (United States). Any VIN beginning with 1C6 decodes to Jeep.
No. They are synthetically generated but checksum-valid, use the real Jeep 1C6 WMI, and carry the Gladiator's descriptor and a valid year code — so a decoder returns a Jeep Gladiator. No real vehicle's VIN is used.
