World Post Day

Mail is truly one of the greatest inventions of humankind—no wonder World Post Day exists! This day is dedicated to celebrating and appreciating the work of thousands of postal workers around the world.

History

World Post Day commemorates the founding of the Universal Postal Union (UPU) in 1874. The Treaty of Bern, resulting from an international conference, established uniform rules for the exchange of mail, allowing carriers to save costs when delivering to different countries. Although the agreement has been amended many times, its main purpose—to ensure worldwide mail delivery at a fixed cost—remains a success.

World Post Day highlights the importance of the UPU, which paved the way for modern mail services. Many organizations and groups continually strive to improve postal systems, focusing on goals like environmental protection and economic sustainability.

Interesting Facts

  • With the rise of the internet, traditional mail is less popular, but it still provides vital services worldwide.
  • Every minute, about 6 million parcels pass through post offices globally.
  • Stamp collecting is the third most popular hobby in the world.
  • The oldest post office still in operation is in Scotland. Founded in 1712, it remains active today.
  • The first woman to be depicted on a stamp was Isabella, Queen of Spain, in 1893.
  • In 1916, an American businessman sent 80 bricks by mail to a neighboring city in multiple parcels because it was more cost-effective than direct delivery. After this incident, postal restrictions were introduced.

How to Take Part

A great way to celebrate World Post Day is by sending a letter. While this tradition has faded in the age of phones and emails, mailing a handwritten note is a wonderful way to surprise a friend. You can also thank your local postal workers for their hard work—it’s a small gesture that can make their day!
