A device for the alphanumeric labeling of printed products comprises a shaft mounted in a frame, and around which shaft at least one wheel-shaped or ring-shaped labeling tool is rotatably mounted, which tool carries a number of alphanumeric characters, one behind the other, on its outer circumference. A drive motor, in the form of, for example, a stepper motor, is provided and by which the labeling tool can be rotated around the shaft. The drive motor is linked for signals transmission to one of a data processing and a data storage of a control device, in which an assignment specification between the working positions of the alphanumeric characters or the fields carrying the alphanumeric characters, and step numbers of the stepper motor, is provided. The drive motor is or can be controlled by the control device in terms of a number of steps to be traveled, using this provided assignment specification, to move an alphanumeric character to be printed or the relevant field into a working position.
