A method that enables a mailer (sender) computer to automatically receive updated and computerized address information for automatic correction of address data in mailing lists of the mailer, said method comprising the steps of: placing a physical Correct Address Information Record in a recipient mail box or a case used in a manual casing process, the Correct Address Information Record containing correct up-to-date recipient personal and geographic address information (PI, GI) describing all current mail recipients associated with the address, and the Correct Address Information Record being readable by a hand-held data capture device; creating, by the mailer, mail containing delivery address information that includes a personal and geographic portion of the address; capturing, by a mail carrier using a hand-held data capture device, the mailer's created delivery address information and the up-to-date personal and geographic address information from the Correct Address Information Record; comparing, by the hand-held data capture device, the captured mailer's created delivery address information and the captured up-to-date personal and geographic address information; if the captured mailer's created delivery address information and the captured up-to-date personal and geographic address information do not match, the hand-held data capture device creating a discrepancy message for personal and geographic portions of delivery address information that can be used for automatic, real-time correction of address data in the mailer's mailing lists; the hand-held data capture device communicating the discrepancy message to the mailer computer; and the mailer computer correcting address data in the mailer's mailing lists using the discrepancy message. placing a physical Correct Address Information Record in a recipient mail box or a case used in a manual casing process, the Correct Address Information Record containing correct up-to-date recipient personal and geographic address information (PI, GI) describing all current mail recipients associated with the address, and the Correct Address Information Record being readable by a hand-held data capture device; creating, by the mailer, mail containing delivery address information that includes a personal and geographic portion of the address; capturing, by a mail carrier using a hand-held data capture device, the mailer's created delivery address information and the up-to-date personal and geographic address information from the Correct Address Information Record; comparing, by the hand-held data capture device, the captured mailer's created delivery address information and the captured up-to-date personal and geographic address information; if the captured mailer's created delivery address information and the captured up-to-date personal and geographic address information do not match, the hand-held data capture device creating a discrepancy message for personal and geographic portions of delivery address information that can be used for automatic, real-time correction of address data in the mailer's mailing lists; the hand-held data capture device communicating the discrepancy message to the mailer computer; and the mailer computer correcting address data in the mailer's mailing lists using the discrepancy message.
