Mail Security Guide

Your agency must have clear procedures for assessing and managing mail security. Every agency is required to develop their own security plans in a Mail Security Guide. These procedures protect the health and safety of federal and civilian employees in federal mail centers. The USPS Mail Security Center provides additional details on mail security.

To request a copy of the Mail Security Guide, contact your Agency Mail Manager. If you do not know who your agency mail manager is, contact our mail management office at
