Celebrates the 125th anniversary of the Universal Postal Union (UPU). The UPU stamp's 45¢ denomination will satisfy the rate for a postal card mailed from the United States to Canada.
The UPU was formed on November 9, 1874, when 22 countries formed the General Postal Union. In 1878, the name Universal Postal Union was adopted. The UPU follows the provisions of the 1874 Universal Postal Convention, which specifies the types of correspondence that can be sent internationally. The UPU is the organization that sets the rules for the free flow of mail between countries.
In 1948, the UPU became a specialized agency of the United Nations. Its headquarters is located in Berne, the capital of Switzerland.
