Disclosure of removed or illegible identification marks occurs when the need arises to establish the origin of the object or attempt to alter the original designation. In order to make it difficult to identify the subject, the offender removes all the marks characterizing the subject while applying a new mark. In addition to the most primitive character removal methods, there are those that make it difficult to evaluate the removal of the original mark. The publication presents selected methods of destructive and non-destructive testing which are used in forensic vehicle identification. The results of research on the detection of forgeries of vehicle identification numbers obtained using the methods discussed are presented in the publication. The presented results illustrate how easy it is to detect the attempts to process car numbers. As a result of the performed tests, the forgeries of a VIN (vehicle identification number) were revealed using the chemical method in a Hyundai Tucson car and the magnetic method in a Nissan car. In addition, using the thermal method, a forgery of the engine number of a Daewoo Matiz car was revealed. In turn, in an Audi A6 car, an attempt was made to counterfeit the VIN using the permanent magnetic method, and the method of replicas was disclosed.
