People in countries belonging to the United Nations send nearly 430 billion pieces of mail each year. But every country in the United Nations has a slightly different postal system. An important role of the United Nations is helping people in these countries send mail to each other.
The Universal Postal Union is an agency of the United Nations that makes sure someone in the United States can mail a letter to Kenya, or receive a letter from Germany. The Universal Postal Union also helps countries make their postal services more modern.
