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 learning’s, 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 05, 2013. You may

access the standards by clicking on DMM Rules for FSMs - see section 201.3.14 under the Important Links.

To further assist customers with understanding the revised rules, a document containing summarized information can be found by clicking on Folded Self-Mailer Reference Material under the Important Links. 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.
