Abstract: An improved mounting plaque system for house numbering includes symbols that are mounted by means of a rear connection in order to leave the front surfaces of the symbols unmarred by holes or other connection devices. The mounting plaque system also has mounting connections predetermined mounting hole pattern through the entire thickness of the mounting plate aligned with predetermined holes on the rear face of the symbols in order to fix the symbols the front surface of the mounting plate. The font of the symbols can be modified in order to maximize the number of mounting connections on the rear face of the symbols that align with mounting holes on the mounting plate.
