Abstract
A method for providing directory assistance, including receiving at least one request from a requester for an un-listed contact information, where the un-listed contact information is stored in one of a plurality of carrier databases. A request is generated to a third party for the un-listed contact information, where the third party is in contact with the carriers, one of which has the un-listed contact information. A notification is received from the third party indicating that the un-listed contact information has been retrieved by said third party and a message is sent to the un-listed contact information, through the third party, indicating that the requester is trying to contact them.
