Folded Self-Mailer

In collaboration with the mailing industry, the Postal Service engaged in a mailpiece design study to revise Folded Self-Mailer (FSM) standards for automation letter-size formats. As a result of those learnings, the revised mailing standards introduce more creative mailpiece design options that better match with mail processing capabilities. These revised mailing standards were effective on January 5, 2013. You may access the standards from Postal Explorer.

To further assist customers with understanding the revised rules, a document containing summarized information can be found in the Folded Self-Mailer Reference Material. The reference guide was developed jointly with the mailing industry and includes supplemental information, with a few sample illustrations and finished mailpiece elements, prepared to comply with the proposed rules.
