This invention provides a system for aiding information providing services utilizing position information identifiers, which is a position information identifier providing system including information providing means (20) for providing to a receiving device (30) containing a database (37) of position information identifiers and a database (38) of a digital map, only the information using said position information identifiers; and position information identifier information providing means (10) for providing only updated position information identifier information to said receiving device, in addition to said information providing means. The system is capable of supplementarily supporting a scheme of providing information by using the position information identifier. The burden imposed on the map data manufacturer, such as the maintenance and after-sales service, which result from the updating of the position information identifier, is lightened. Further, there is no need of transmitting the new and old position information identifiers redundantly to the VICS information.
