Effective June 26, 2025, the Postal Service™ is revising Mailing Standards of the United States Postal Service, International Mail Manual (IMM®), Exhibit 292.45a and Exhibit 293.45a, to update the foreign office of exchange codes for items send to Italy via:
n International Priority Airmail® (IPA®); and
n International Priority Surface Air Lift® (ISAL®).
Periodically, the Postal Service receives such requests from foreign posts to facilitate operational needs. These revisions are based on consultation with Poste Italiane (the designated postal operator for Italy). To provide mailers sufficient time to make necessary logistical and software changes, the Postal Service (through this Postal Bulletin article) is providing advance notice that mailers must begin using the appropriate foreign office of exchange code for IPA and ISAL M-bags effective September 28, 2025. However, mailers are encouraged to immediately implement this change to expedite delivery.
