Effective March 20, 2025, the Postal Service™ is revising the Individual Country Listing for Curacao in Mailing Standards of the United States Postal Service, International Mail Manual (IMM®) to add an observation about including the addressee’s mobile phone number and email address when mailing certain items to Curacao.
This revision is based on a formal request that Cpost International N.V. (the designated postal operator of Curacao) made through the Universal Postal Union via International Bureau Circular 16, dated February 10, 2025.
