Abstract: The invention relates to a system and method for processing a mailing consisting of a plurality of identical printed items to be grouped into bundles having an identical general address. Information as to bulk mailing centers (BMC) is accessed, which information provides an associated BMC for each group of zip codes, based generally on geographical proximity to a certain BMC. Information as to postal zones and rates to a particular zip code from the BMCs is also accessed, so that postal rates for each bundle can be calculated. Addressee information is provided to the system, including a general address having a zip code and particularized information for each addressee. The addresses should preferably be compatible with the particular bulk mailing procedures being used. Alternatively, the addresses can be screened for compatibility after being input into the system. The labeling, bundling and palletizing of the items are optimized for maximum efficiency.
