A method for the Postal Service to provide updated address information to its customers such as mass mailers. The method includes comparing information on old delivery point files with information on current delivery point files. The delivery point files include unique identifiers that are keyed to each delivery point. Thus a comparison of older and newer files identifies delivery points that have been changed by, for example, changes in street name or renumbering of address numbers. The comparison of files generates a file with updated delivery and address information. In modified format this updated address information can be made available to mass mailers so that mass mailers will have the most up-to-date address information for mailings.
