The VIN is 17 characters in length.
Important information about a vehicle is associated with this number, including the vehicle make, model, and year; the plant where the vehicle was manufactured; and the type of engine in the vehi- cle.
The VIN decoder is an excellent example of a service. It takes in a bit of data (the VIN) and produces a very detailed description about a vehicle.
The service doesn’t care what transaction originated the VIN; its job is to always produce the same result — a full listing of the details of the vehicle.
