1. A computer-implemented method of determining mailpiece routing information based on a mailpiece image, comprising the steps of: receiving, using at least one processor at a remote computer reader, the mailpiece image including an identification tag associated with the mailpiece image, from an image control unit when a routing barcode of the mailpiece cannot be resolved; receiving a master reference table of identification information from the image control unit, the master reference table being retrieved by the image control unit from a central database; determining whether the master reference table includes an identification file including routing information associated with the identification tag of the mailpiece image; transmitting the identification file corresponding to the mailpiece image to the image control unit, if the identification file was determined based on the master reference table; and assigning a priority designation to the mailpiece image for further processing, if no identification file was determined based on the master reference table.
