Abstract
Abstract An electronic device for providing information related to an input telephone number includes a keyboard unit for providing an input telephone number and a memory unit for storing an IDDD code and a database including country code entries, country name entries which correspond to the country code entries, area code entries, area name entries which correspond to the country code entries, and information related to each of the country name and the area name entries. A central processing unit receives the input telephone number from the keyboard unit and compares the received input telephone number with the contents of the memory unit. The central processing unit then controls a display unit to show the input telephone number, the country name entry and the area name entry corresponding to the input telephone number, and the information related to the country name entry and the area name entry corresponding to the input telephone number. The electronic device is intended for use with another electronic device which is capable of dialing or storing telephone numbers.
