Processing of undeliverable as addressed mail

1. A computerized method comprising:

sorting mail that comprises a multiple pass mail sort operation for a mail piece that is undeliverable as addressed, comprising

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;

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 being derived from the feature of the mail piece that is identified during the first pass; and

performing the second pass of the multiple pass mail sort operation, wherein performing the second pass comprises

uniquely identifying the mail piece relative to other mail pieces being sorted in the multiple pass mail sort operation based on a fingerprint that is derived from a feature of the mail piece and without using a bar code, and

determining a final disposition of the mail piece that is undeliverable as addressed, wherein the fingerprint is used to uniquely identify the mail piece during the determining of the final disposition.

2. The computerized method of claim 1 , wherein the multiple pass mail sort operation is executed by a delivery bar code sorter.

3. The computerized method of claim 1 , wherein the multiple pass mail sort operation is executed by a flat sequencing mail sorter.

4. The computerized method of claim 1 , wherein the multiple pass mail sort operation is executed by a parcel mail sorter.

5. The computerized method of claim 1 , wherein the final disposition of the mail piece that is undeliverable as addressed comprises at least one returning the mail piece to a sender of the mail piece, forwarding the mail piece to a different address, and disposing of the mail piece.

6. The computerized method of claim 1 , wherein the feature includes at least one of a size of the mail piece and a return address of the mail piece.

7. The computerized method of claim 1 , wherein determining the final disposition of the mail piece that is undeliverable as addressed is independent of use of a bar code by the multiple pass mail sort operation for identification for final disposition of the mail piece.

8. The computerized method of claim 1 , wherein performing the second pass of the multiple pass mail sort operation comprises uniquely identifying the mail piece relative to other mail pieces being sorted in the multiple pass mail sort operation based on the fingerprint that is derived from the feature of the mail piece, and wherein the uniquely identifying of the mail piece does not include use of the bar code.

9. A machine-readable medium including instructions which when executed by a machine causes the machine to perform operations comprising:

sorting mail that comprises a multiple pass mail sort operation, wherein the multiple pass mail sort operation comprises,

performing a first pass of the multiple pass mail sort operation to sort mail by carriers of the mail; and

performing a second pass of the multiple pass mail sort operation to sort the mail by sequence for a carrier of the carriers of the mail, wherein performing the second pass comprises

uniquely identifying the mail piece relative to other mail pieces being sorted in the multiple pass mail sort operation based on a fingerprint that is derived from a feature of the mail piece and without using a bar code, and

determining a final disposition of a mail piece that is identified as undeliverable as addressed.

10. The machine-readable medium of claim 9 , wherein the multiple pass mail sort operation is executed by a delivery bar code sorter.

11. The machine-readable medium of claim 9 , wherein the multiple pass mail sort operation is executed by a flat sequencing mail sorter.

12. The machine-readable medium of claim 9 , wherein the multiple pass mail sort operation is executed by a parcel mail sorter.

13. The machine-readable medium of claim 9 , performing the first pass for a mail piece comprises:

determining a delivery point bar code for the mail piece;

collecting data to identify a name of a recipient of the mail piece;

determining whether the mail piece is a candidate undeliverable as addressed mail piece based on at least one of the delivery point bar code and the name of the recipient; and

capturing an image of the mail piece if the mail piece is determined to be a candidate undeliverable as addressed mail piece.

14. The machine-readable medium of claim 13 , wherein the multiple pass mail sort operation comprises generating a fingerprint, between the performing the first pass and the second pass, for a mail piece that is identified as a candidate undeliverable as addressed during the first pass.

15. The machine-readable medium of claim 14 , wherein the fingerprint is derived from a feature of the mail piece that is identified during the first pass.

16. The machine-readable medium of claim 15 , wherein the feature includes at least one of a size of the mail piece and a return address of the mail piece.

17. The machine-readable medium of claim 13 , wherein the final disposition of the mail piece that is undeliverable as addressed comprises at least one returning the mail piece to a sender of the mail piece, forwarding the mail piece to a different address, and disposing of the mail piece.

18. The machine-readable medium of claim 13 , wherein determining the final disposition of the mail piece that is undeliverable as addressed is independent of application of a bar code by the multiple pass mail sort operation for identification for final disposition of the mail piece.

19. An apparatus comprising:

a mail sorter to receive mail and to execute a first pass and a second pass to sort the mail, wherein as part of the first pass the mail sorter is to capture data to identify a feature of a mail piece in response to a determination that the mail piece is a candidate undeliverable as addressed, wherein as part of the second pass the mail sorter is to determine a final disposition of the mail piece, and wherein determination of the final disposition of the mail piece that is undeliverable as addressed is independent of a placement of a bar code, during the sort of the mail, for identification for final disposition of the mail piece; and

an undeliverable as addressed module is to generate a fingerprint for the mail piece between the first pass and the second pass, wherein the fingerprint is derived from the feature of the mail piece that is identified in the first pass, wherein the fingerprint is used by the mail sorter in the second pass to uniquely identify the mail piece for determination of the final disposition of the mail piece.

20. The apparatus of claim 19 , wherein the mail sorter comprises at least one of a delivery point bar code sorter, a flat sequencing mail sorter and a parcel mail sorter.

21. The apparatus of claim 19 , wherein the final disposition of the mail piece that is undeliverable as addressed comprises at least one return of the mail piece to a sender of the mail piece, forward of the mail piece to a different address, and disposal of the mail piece.

22. The apparatus of claim 19 , wherein the feature includes at least one of a size of the mail piece and a return address of the mail piece.

23. The apparatus of claim 19 , wherein as part of determination of the final disposition of the mail piece the mail sorter is configured to uniquely identify the mail piece relative to other mail pieces being sorted based on the fingerprint that is derived from the feature of the mail piece, and wherein the uniquely identifying of the mail piece does not include use of the bar code.
