Where to find the VIN on a Hummer

- Dashboard, driver side
Look through the windshield in the lower left corner, where the dash meets the glass.

The sticker or plate on the B-pillar or door edge (Federal Motor Vehicle Safety Standard label).
- Engine bay or frame
Stamped on the firewall or, on trucks, on the frame rail near the front wheel.
- Title certificate
Every state title shows the VIN near the year, make and model.

The registration card in the glove box repeats the VIN.

If the VIN on the title differs from the one on the dashboard, do not buy until it is explained.

Your insurance card or app lists the VIN of each covered vehicle.

How to recognize a Hummer VIN
Hummer is a brand from the United States. The first three characters of the VIN (the WMI code) identify the maker and, often, the plant or the market the vehicle was built for.
Example: a VIN that starts with 5GR stands for Hummer H2, USA. The 10th character is the model year; the last six characters are the production number. A VIN that starts with another code is not necessarily a problem (makers change codes over time), but it is worth checking the history before you buy.
