A sorting device and method for dynamically allocating bins to objects such as mail pieces. The device has at least one reading device for reading delivery information of objects and a conveying system which transports the objects. At least one feeder inducts the objects onto the conveying system. A plurality of physical bin locations are adjacent to the conveying system for storage of the object injected from the conveying system. A controller or processor dynamically assigns and reassigns sort locations, as required, to the plurality of physical bin locations during a sorting operation for each object of the objects.
