A method and a device monitor the transport of an object, particularly of a piece of mail that is provided with a delivery point, to which the object is transported. A sorting system reads the delivery point and generates a first attribute vector differentiating the object from all other transported objects. The first attribute vector and the read delivery point are stored. At the conclusion of the transport a second attribute vector is generated for the object. The object is identified by the second attribute vector. A central computer determines from which of those objects, having run through the sorting system at a predetermined period, the information transmitted originates.
