Patent ID: 8165909

Claim:
A method for managing an address database comprising: reading, using a scanning device, delivery point data from a plurality of mailpieces for a predetermined time interval, wherein the delivery point data comprises digits of delivery point barcodes uniquely identifying delivery points for the mailpieces; storing the digits of at least one of the delivery point barcodes in association with density data comprising a number of the mailpieces addressed to an address represented by the at least one of the delivery point barcodes; storing, in association with the density data, a site identifier of a facility at which the delivery point data was read; determining, by a computer, whether the density data exceeds a predetermined threshold for density data; and determining whether the address represented by the at least one of the delivery point barcodes is stored in the address database, wherein the method further comprises: adding, by the computer, the address represented by the at least one of the delivery point barcodes to the address database based at least on a determination that the density data exceeds the predetermined threshold for density data and a determination that the address represented by the at least one of the delivery point barcodes does not exist in the address database; or deleting, by the computer, the address represented by the at least one of the delivery point barcodes from the address database based at least on a determination that the density data does not exceed the predetermined threshold for density data and a determination that the address represented by the at least one of the delivery point barcodes exists in the address database.
