A vehicle identification number - known as VIN for short - is an internationally standardised serial number by which a vehicle can be clearly identified. Before 1981, this number was still known as the chassis number. It consists of 17 alphanumeric characters and can be found both in the vehicle registration document and several times on the vehicle itself.
The VIN is located on the driver's side door frame and in the chassis itself. Especially for trucks, the VIN is set in the tachograph during production or in the workshop. In trucks, the vehicle identification number (VIN) data can therefore be checked via the tachograph: It can be found in the menu under vehicle information and is also on every printed report of the tachograph.
Quite simply: to identify a vehicle. Since every vehicle on the road has its personal number, it can be assigned to the owner and thus prevent the resale of stolen vehicles, for example. In addition to the technical vehicle data, the VIN check can also record other historical information such as the number of previous owners, service actions, and information about accidents.
Each manufacturer has its own individual composition of the VIN. The identification number usually consists of the following blocks:
