HUMMER VIN Decoder

Locations vary from manufacturer to manufacturer. However, there are three places you can find the code on most vehicles:

- Look through the windshield at the dashboard. On the driver’s side, you should see a small metal plate with the number stamped into it.
- Open the driver’s door. Look at the front and side of the door pillar for an I.D. sticker. It usually has the manufacturer’s logo on it. The code should be on this sticker.
- Open the hood. You may see a sticker on the firewall or near the passenger’s side strut tower. Some cars have the number engraved in one of these areas.

Since this number is used to identify the vehicle on official documents, you can also find it on the title, the window sticker, and on insurance policies.

We also decode numbers for RVs, heavy-duty trucks and motorcycles. If you need to decode an RV number, make sure it’s the one issued by the chassis manufacturer, not the RV outfitter.

No. Canadian and Mexican cars usually use the same format. Other countries use their own formats.

It’s up to the manufacturer to determine what they want to include for some parts of the number. For example, some companies don’t include information about transmissions or trim levels.

Usually, no. A few manufacturers stamp the code into the engine. If the VINs on the engine and car match, then it’s the original engine. On most vehicles, there isn’t anything that ties an engine to a specific vehicle. At most, looking up the vehicle on our website will tell you if a different type of engine was installed. For example, if someone swaps a V8 into a Ford Mustang, our site will tell you it originally came with a V6.
