The number VIN (vehicle identification number) is the vehicle's serial number. It can be found on the E line of the registration certificate. It is similar to the number engraved on the car's chassis. Each manufacturer must assign a vehicle identification number (VIN code) to each car it produces. The VIN code is also called the NSV (Vehicle Serial Number) code. The VIN code is composed of a series of 17 characters.  Example MERCEDES GLA 200 CDI 136hp - 2017 - WDC1569081J370204   The VIN code is formed from the WMI manufacturer code, which is equivalent to the first three characters. Then the VDS code which consists of 8 characters and the last 6 correspond to an internal manufacturer number.
