World Post Day

Mail is perhaps one of the greatest inventions of mankind—it’s no wonder why World Post Day exists. This day is dedicated to celebrating and appreciating the work of thousands of postal workers all around the world.


World Post Day commemorates the establishment of the Universal Postal Union (UPU) in 1874. The treaty of Bern, a result of an international conference, was created to set uniform rules for the exchange of mail, ensuring carriers the rights to save money in different countries. This agreement has been amended multiple times, but its main purpose, to deliver mail to all around the world at a fixed cost, has been successfully completed.

World Post Day celebrates the importance of the UPU, as it paved the way for modern mail. Numerous organizations and groups are always striving to improve mail services, such as environmental protection and economic sustainability.
