Vehicle Identification Numbers (VINs) Vehicle Identification Numbers are unique codes given to each on-road vehicle in the United States. From 1981, each new car is given a standardized 17-digit code, which includes a serial number. Older cars may have VINs too, although they will not follow the standardized formula.

You can find out a lot about your car or truck if you are able to read and decode its VIN number, and that's why we are going to show you how to do just that.
