There are many reasons to use our free GMC VIN decoder, but the most common is that you want to learn the vehicle history of a used GMC truck before you guy or sell it. Whether you are looking for information about a Sierra, Yukon, Terrain, Canyon or Acadia, our GMC VIN decoder will tell you what you need to know in order to make an informed buying and selling choice, including:
No. GMC RPO codes – known as Retail Production Option codes – are used and set up by GMC itself. They are not part of the government-mandated VIN number system. And GMC reuses their RPO codes very often, so no single code really matches a specific vehicle. Instead, we use the VIN number to provide you with detailed information about the exact vehicle. GMC RPO codes are not a part of our free VIN decoder system.

Our GMC VIN decoder does not provide you with the build sheet for the truck you are looking at. This information is part of a different system. If you want the build sheet for a GMC truck, you are better off not using a VIN decoder. Instead, you can look up a GMC build sheet using a simple Google search. Using a GMC VIN decoder to search for a build sheet is not practical.
You can only use a GMC VIN decoder to pull up the gear ratio for a Canyon, Yukon or other GMC truck if it has been mentioned in service reports done on the vehicle. The gear ratio is not usually covered in the VIN number, so using a GMC VIN decoder will not pull up the gear ratio.
For the same reasons you can't generally use a GMC VIN decoder to pull up the gear ratio, you probably can't use a GMC VIN decoder to pull up the axle ratio. But the GMC VIN decoder might pull it up if the axle ratio was mentioned in service records.
You sure can! To get your GMC VIN lookup started, look at the window sticker for the VIN number. Then enter that VIN number into our search system. Once you have done your GMC VIN lookup, go back to the window sticker and see if the information we have found matches what the sticker says.
