The invention relates to the field of identification of material resources and can be used for marking the conductive parts, for example, rolled products, parts of transport facilities, parts of mechanical engineering, aircraft building etc. The method consists in that the surface of the identification mark is divided info two parts: unchangeable and changeable. On the unchangeable part, containing the identification number, it is applied an irreproducible image, and the changeable part is divided into several sectors, in accordance with the number of technological processes to be passed by the identifiable part. The irreproducible image is covered with a dielectric pattern-patch, and each sector of the changeable part is filled with identification information during passage by the identifiable part of the recurrent stage of the technological process.
