What's a VIN & How to Use the Check Digit
Vehicle identification numbers can provide a large amount of information about your Jeep and are like a social security number for your vehicle. Using the charts below, you can take your Jeep's VIN number, or the Jeep you're planning on buying, and dissect what each digit means.
The check digit is position nine of the VIN. This number is the result of a lengthy math problem using the VIN's other numbers. If you're looking to make sure the VIN you have or are looking at is legitimate, the check digit will tell you.
Each position of the value has a numerical weight. "But there are letters in my VIN!", you say. As there should be. Since we're talking Wranglers, odds are you have a J in position two. J's value is 1, and the weight is seven. You would find the value and weight for the rest of the positions, plug them into the VIN calculation, and you should get your check digit as a result.
