PROCESSING OF UNDELIVERABLE AS ADDRESSED MAIL

In some example, a computerized method includes sorting mail that comprises a multiple pass mail sort operation. 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 comprises generating a fingerprint for the mail piece between performing the first pass and performing a second pass of the multiple pass mail sort operation. The fingerprint is derived from the feature of the mail piece that is identified during the first pass. The multiple pass mail sort operation comprises performing the second pass of the multiple pass mail sort operation, wherein performing the second pass comprises determining a final disposition of the mail piece that is undeliverable as addressed, wherein the fingerprint is used to identify the mail piece during the determining of the final disposition.
