World Post Day is celebrated each year on 9 October. The event was declared by the 1969 Universal Postal Congress in Tokyo to mark the anniversary of the Universal Postal Union's creation in 1874.
The purpose of World Post Day is to bring awareness to the Post's role in the everyday lives of people and businesses, as well as its contribution to global social and economic development.
So, the UPU's member countries are encouraged to organize their own national activities to celebrate the event, including everything from introducing or promoting new postal products and services, to organizing open days at post offices, mail centres and postal museums.
For countries participating in the UPU International Letter-Writing Competition, national winners are often honoured on 9 October. This year, the winner will be invited to the World Post Day ceremony taking place at the UPU International Bureau in Berne, Switzerland, to receive their award.
