Carrier Route Product provides mailers with reference information for applying carrier route codes to addresses when taking advantage of presort postage discounts. Mail containing carrier route codes can then be presorted to the carrier route level.

Carrier Route Product is available with monthly or bimonthly updates on CD-ROM and cartridge. The hardcopy report offered in the pass has been replaced with the ZIP + 4 Retrieval option found on the AIS Viewer CD-ROM. Using the ZIP + 4 Retrieval option, mailers can retrieve, view and print hardcopy reports on demand similar to the Carrier Route Information System (CRIS) hardcopy reports.

Mailers are encouraged to update their files when they receive updates from the Postal Service or vendors, and carrier-presort mailers must comply with the established mandatory update cycles specified by the USPS in the DMM® reference manual.

A sample Carrier Route file is available for download.
