The vehicle identification number isn’t just a random combination of letters and numbers. In fact, each sequence of characters contains specific information about each and every vehicle. 

The VIN decoder uses these unique character sequences to lookup the values for every vehicle and return the details the database contains about it. 

While you can certainly just plug in your VIN above and get back the data you need, it can also be helpful to understand how to decode the VIN.
