AnalogX VIN View is a free online VIN decoder that allows you to see the information about your vehicle that it contains. VIN View supports decoding of any vehicle identification number that was issued after 1978, which is when ISO 3779 was established to make a uniform way to track vehicles. If you have a car you would like to lookup prior to 1978, I would recommend going to Wikipedia , they have one of the more comprehensive listings of VIN's plus some additional related information.
    Operation is simple, enter the VIN number (17 characters, A thru Z and 0 thru 9) and click decode. On the decode page you'll see your VIN again and the position of each character, then on the bottom portion you'll see what position and characters map to what information. As more information becomes available, more details about the vehicle will be displayed (such as the model, engine size, options, etc), please be patient!
    VIN's are normally located in several locations on a car, but the most common places are in the door frame of the front doors, on engine itself, around the steering wheel, or on the dash near the window. If you can't find it in any of those areas, then don't ask me because I certainly don't know! :) Either call the dealership for the car manufacturer and ask them, or search online for a site dedicated to your particular vehicle (or check the above mentioned site).
