For instance, if someone wants to buy a car, it is possible to check the VIN number one the online database to ensure that the car was not stolen, damaged or illegally modified. The VIN number has a specific format that is globally recognized. This format was implemented by the ISO institute. Every car manufacturer is obliged to mark all its vehicles in this special format. This online service allows a user to check the validity of the car and get detailed information on almost any VIN number, search car parts and check the car's history. The VIN also allows a user to check the market value of a new or used car.
