Abstract: A sequential mail sorting system for generating sort sequence codes, interpreting them for the sequential sorting of mail into a mail carrier walk sequence and providing for holdout mail types, which includes reading a sort plan text file for a selected postal delivery zone and determining the number of bins required in the sorting machine, selecting the carriers whose routes are located in such zone, generating sort sequence codes for sorting the mail in a sequential order, and generating sequence codes for holdouts and regular mail types and placing them into a sort plan binary file. The generating of sort sequence codes includes generating and interpreting sort sequence codes for holdout mail types to allow for sorting and removal of holdout mail from the mail sorting stream in the initial sorting pass of a multiple pass sequential mail sort. It also includes such a step which is performed in the final sorting pass.
