Personal address updates using directory assistance data

Methods and systems are provided for storing directory assistance information in a subscriber's electronic address book for future use. If a directory number associated with the desired called party is not in the subscriber's address book, a voice services node initiates a call to a directory assistance service to obtain a directory number for the called party. If the subscriber would like to have the obtained number added to the subscriber's address book, the directory number, name and address associated with the requested directory assistance may be added to the subscriber's address book for future use by the subscriber when the subscriber needs the directory number associated with the called party.
