A system for confirming the identity of a vehicle. The device includes: a vehicle control unit in the vehicle to be identified; a vehicle identification device; an external service device designed to interact with the vehicle; a vehicle sensor in the vehicle; and an external sensor. The vehicle identification device establishes a data connection with the vehicle control unit and triggers a physical interaction between the vehicle control unit and the external service device. The vehicle sensor detects the physical interaction and transmits a corresponding vehicle detection value to the vehicle identification device. The external sensor detects the physical interaction and transmits a corresponding external detection value to the vehicle identification device; and the vehicle identification device compares the vehicle detection value and the external detection value with one another and confirms the identity of the vehicle if the two detection values coincide with one another within a predefined tolerance.
