The present invention provides a system and method for providing a peer-to-peer contact information look-up system. A user who seeks contact information may enter an identification query, such as a name or other identifier. A first level search may be performed by determining whether any contacts contained in the user's electronic address book satisfy the query. If the contact is not found in the user's personal electronic address book, then the query may be transmitted to a plurality of other participant electronic devices in the system, thereby initiating a second level search. The devices that receive the query in the second level search may then search their personal electronic address books for the contact. If the contact is identified, the contact information is sent to the user device from which the query was initiated. If, however, none of the second level devices can identify the contact, each of the second level participant devices may transmit the query to a plurality of other participant devices in the system, thereby initiating a third level search. The personal address books of each of the third level devices are searched for the contact, and so on until the contact is found or the search terminates.
