Abstract: A computerized method includes sorting mail that comprises a multiple pass mail sort operation, wherein the multiple pass mail sort operation for a mail piece that is undeliverable as addressed comprises performing a first pass of the multiple pass mail sort operation, wherein performing the first pass comprises capturing data to identify a feature of the mail piece. The multiple pass mail sort operation also includes generating a first fingerprint for the mail piece between performing the first pass and performing a second pass of the multiple pass mail sort operation. The multiple pass mail sort operation also includes performing the second pass of the multiple pass mail sort operation. Performing the second pass includes determining a final disposition of the mail piece that is undeliverable as addressed.

Abstract: Some embodiments include a machine-readable medium including instructions which when executed by a machine causes the machine to perform operations. The operations include sorting mail. The sorting of the mail includes reading an encoded value located on the mail piece. The sorting of the mail includes decoding the encoded value to determine a delivery point for the mail piece, an identification of a sender of the mail piece, an identification of a recipient of the mail piece, an identification of a class of the mail piece and an identification of a service type of the mail piece. The sorting of the mail includes determining whether the mail piece is a candidate undeliverable as addressed mail piece using the identification of the recipient of the mail piece within the encoded value and the identification of a delivery point for the mail piece within the encoded value.
