Enter a 17-character VIN and the decoder tells you who built the vehicle, which model year it belongs to and in which country it was made. For Hummer, our data covers three models, the H1, H2 and H3, with model years from 1993 to 2010. All of them are listed as SUV, and the highest power figure in our data is 398 hp.
The decoder reads only the VIN itself, so it cannot tell you anything about accidents, mileage, theft or previous owners. That information comes from a paid vehicle history report, and the decoder on this page is free and needs no registration.
The first three characters are the World Manufacturer Identifier, or WMI. For Hummer we recognise 5GN, 5GR and 5GT, and all three belong to the United States. A VIN that starts with one of these codes points to a US-built vehicle. Our list of codes is not complete, so it only shows the ones we can match to the brand today.
Characters 4 to 8 form the descriptor section, which the manufacturer uses to describe the vehicle. Character 9 is the check digit, which is required in North America and therefore matters for a US-built Hummer. The tenth character is the model year, and it is the quickest part to check by hand. A 6 stands for 2006, a 3 for 2003 and a W for 1998, all inside the 1993 to 2010 range in our data.
Character 11 marks the assembly plant, and characters 12 to 17 are the serial number of that particular vehicle. The letters I, O and Q are never used in a VIN, so if you are copying one from a document, a zero is a zero and a one is a one.
Every VIN has six parts. This is what each of them means.
| Part | Characters | Meaning |
|---|---|---|
| WMI | 1 to 3 | World manufacturer identifier: who built the vehicle and where |
| VDS | 4 to 8 | Vehicle descriptor: model, body type and engine, as set by the manufacturer |
| Check digit | 9 | Control value that helps confirm the VIN is valid |
| Model year | 10 | Code for the model year |
| Plant | 11 | Code for the assembly plant |
| Serial | 12 to 17 | Production sequence number of this vehicle |
On the driver's side, visible through the windshield.
On a sticker on the door frame or the edge of the door.
Printed in the vehicle registration or title.
Stamped on the firewall or the frame on many models.
A VIN is built from six parts, and each one says something about the vehicle. Our guides explain how to read it and what it can and cannot tell you.
Enter the 17-character VIN and see the factory basics in seconds.
Start with the registration documents, where the full 17 characters are printed. On the vehicle itself, the VIN is usually visible at the base of the windshield on the driver's side and on the label in the driver's door frame. Compare the number on the vehicle with the one on the paperwork.
The first three characters are the WMI. We map 5GN, 5GR and 5GT to Hummer, and all three are assigned to the United States. A VIN beginning with other characters is not necessarily a problem, because our list does not cover every code.
Look at the tenth character. Letters and digits map to years, for example 3 is 2003, 6 is 2006 and A is 2010. Our version data for Hummer runs from 1993 to 2010, and the decoder shows the year for you once you enter the VIN.
It cannot show accidents, mileage, theft records or the number of owners, because none of that is stored in the VIN. It also says nothing about the condition of the vehicle or how it was maintained.
Make sure the VIN on the vehicle matches the one in the registration papers and that the tenth character fits the model year in the advert. Then inspect the vehicle in person, ask for service records and, if you can, have a mechanic look it over before you pay.
