Domestic Bound Printed Matter (BPM)

Bound Printed Matter (BPM)

BPM includes many types of printed material: advertising, promotional, directory and/or editorial. It must be securely and permanently bound, and at least 90 percent of its contents must be imprinted rather than typewritten. A wide range of material falls under this heading, from books and catalogs to annual reports, directories and informational kits. If you frequently ship printed material, we can help you deliver it quickly, reliably and economically.

Flat Mail


Flats are also called “flat mail” or simply “large envelopes.” They’re too long in at least one direction to be classified as a letter. However, they’re small and flexible enough to fit through a sorting machine. Many common items can be classified as flats, including advertisements, catalogs, questionnaires, welcome packets and more. Through the OSM Premium Network, we can deliver flats domestically within two to five business days.
