Effective October 31, 2024, the Postal Service™ is revising Mailing Standards of the United States Postal Service, International Mail Manual (IMM®) Exhibit 292.45a to change the office of exchange code for Saint Kitts and Nevis from “SKB” to “BAS” for International Priority Airmail® (IPA®) items sent to Saint Kitts and Nevis. This revision is based on current international transportation routing.
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 code by January 19, 2025. Nonetheless, mailers are encouraged to immediately implement this change in order to expedite delivery.
