Fast facts
The story
Long before email, people found a way to get messages to one another, often by messenger on horseback. By the late 1800s, international mail had grown complex and inefficient, so on October 9, 1874, delegates in Bern, Switzerland signed the Treaty of Bern, creating what became the Universal Postal Union. Nearly a century later, at the 1969 UPU Congress in Tokyo, October 9 was declared World Post Day on a proposal from India's Shri Anand Mohan Narula.

There is something deeply human about mail. A letter is a physical piece of someone's time, folded and sealed and carried across town or across the planet. Postal workers brave every kind of weather to deliver medicine to remote villages, college acceptances to nervous seniors, and birthday cards that arrive exactly when they are needed most.
Today more than 150 countries take part in World Post Day celebrations. Post offices introduce new stamps, host exhibitions and open days, and honor their employees. This year's theme, One postal network, infinite possibilities, celebrates how a trusted global network keeps connecting people, businesses, and communities. In India, the day even opens National Postal Week, a full seven days of postal appreciation.
