World Post Day

World Post Day is celebrated annually on October 9. In 2026, this date falls on a Friday. The day honors the establishment of the Universal Postal Union in 1874 and recognizes the essential role postal services play in connecting people and businesses worldwide.

History of World Post Day

World Post Day was declared by the Universal Postal Congress held in Tokyo, Japan in 1969. The date was chosen to mark the anniversary of the Universal Postal Union's (UPU) creation on October 9, 1874, in Bern, Switzerland. The UPU is the second oldest international organization, coordinating postal policies among its member nations and becoming a specialized agency of the United Nations in 1948.

The purpose of the day is to raise awareness of the postal sector's contribution to the social and economic development of countries. Member countries are encouraged to organize national activities, such as introducing new postal products and services, holding open days at post offices and mail centers, and issuing special stamps. The UPU's International Letter-Writing Competition for young people also honors its national winners on this date.
