Abstract

A distributed computer system enables end-users without direct access to a ZIP+4 database to obtain ZIP+4 zipcode values for specified addresses from a remotely located computer having a ZIP+4 database. The remotely located computer includes a modem for receiving calls from end-user's computers and a ZIP+4 database with query response software for transmitting ZIP+4 zipcode values retrieved from its ZIP+4 database in response to address information received from end-user computers. End-user computers that utilize the remotely located ZIP+4 database each include a modem for communicating with the remotely located ZIP+4 database computer, an address input program for storing address information input by a user, and a remote zipcode retrieval program for transmitting via the modem the stored address information to the remotely located ZIP+4 database computer and for receiving ZIP+4 zipcode values from the remotely located computer. The end-user computers preferably include a printer, and an envelope printing program for directing the printer to print ZIP+4 barcodes on envelopes, as well as other post-office mandated artwork. The address input program on the end-user's computer preferably is linked to the remote zipcode retrieval program such that a single predefined keystroke by the user causes the end-user's computer to call the remotely located computer, send a specified set of address information, receive ZIP+4 zipcode values, and insert the received ZIP+4 zipcode values into the stored address information.
