A method is for detecting the position of at least one mobile, interchangeable load carrier that is movable by a commercial vehicle, in a delimited detection area, in particular a depot, in which the at least one mobile, interchangeable load carrier is moved by vehicles. Accommodation operations and/or offloading events of the mobile, interchangeable load carrier in the detection area are determined by the vehicle as notification events, position data for identifying the position in the detection area are determined for the notification events, and position notification signals are formed by the commercial vehicle from the determined notification events and from the position data, and are transmitted to a communication center of the detection area via a wireless network. In the communication center, the current position data of the load carrier are determined from the received position notification signals and are stored in a memory and continuously updated.
