As one of the most popular vehicles ever manufactured, the Jeep has been produced in so many styles over the years that even enthusiasts can get confused when it comes to the model codes. For instance, what's a JK and how does it differ from a YJ? And it's not just the iconic Jeep Wrangler that has a code—every Jeep ever made has one, so buyers know exactly what make and model they are looking at.
