Effective April 1, 2025, the Postal Service™ refined service standards for domestic retail and commercial Priority Mail Express® delivery service.
Although the Postal Service implemented these new standards April 1, 2025, the revisions will be included in the July 13, 2025, edition of Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®).
Various sections of the DMM will be revised to align with operational initiatives that the Postal Service is implementing nationally to fundamentally transform the Postal Service processing and transportation networks to achieve greater operational precision and efficiency, significantly reduce costs, and enhance service in accordance with the Postal Service’s Delivering for America® strategic plan (DFA Plan).
Priority Mail Express delivery service will have a 1-day, 2-day, or 3-day service standard depending on various factors, including the mail item’s origin and destination 5-digit ZIP Code™, and the date on which the Postal Service officially accepted the item.
This revised standard will not affect other Priority Mail Express product features. Priority Mail Express will continue to be a money-back guaranteed product with delivery available 7 days per week in certain areas.
