A: The U.S. Postal Service, as a member of the Universal Postal Union, works with postal administrations around the world to develop policies and procedures and rates for the exchange of mail between countries, Postal Service spokesman Michael Miles said.
If an item meets mailability standards (available at pe.usps.com), it will be accepted and delivered to the destination country. However, after an item has been delivered to the postal administration in the destination country, it is subject to the rules, regulations and guidelines of the destination country, Miles said. The intergovernmental Universal Postal Union, created in 1874, is an agency of the United Nations and is composed of 191 members from around the world.
