Effective April 6, 2026, the Postal Service™ will revise Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®), sections 604.9.5.2 and 604.9.5.5, to be consistent with Postal Service requirements for Priority Mail Express Military® service refunds and other related refund information in the DMM.
