The system is used for imprinting indentification code on individuals of articles such as automobiles produced in quantity, particularly on an assembly line, and comprises an instruction unit to provide a data signal representing an identification code to be imprinted, a stamping machine in which setting of imprinting types is performed automatically according to the data signal, a sensor which provides a signal representing an actual state of the type setting, and a comparator which provides an operation signal to the stamping machine only when the signal from the sensor agrees with the data signal and otherwise provides an alarm signal. For further accuracy of imprinting operation, the system may include a sensor to detect the type of the individual article to be imprinted and another comprator to prevent the action of the stamping machine also when the type of the article differs from one implied by the data signal.
