Abstract
A computer-based system for correlating an address to the current switched network telephone number(s) assigned to and operational at the address.

One of the data processing systems, the User system, transmits an address to the Telephone Number Administration System. The Telephone Number Administration System includes a data storage facility containing records which relate addresses and possibly other information to the current telephone number or numbers which are assigned to and operational at each address. Upon receiving an address from a User system, the Telephone Number Administration System performs a search of the records and identifies the telephone number(s) assigned to the address or addresses which most closely match the address received from the User system. The telephone number(s) obtained from this search may be transmitted by the Telephone Number Administration System back to the User system or to any other data processing systems which require the result of this correlati…
