Red-letter day for Posts

World Post Day is celebrated on 9 October and marks the founding of the Universal Postal Union in 1874.

Every year, more than 150 countries mark the day in a variety of ways.

Many Posts use the event to introduce or promote new postal products and services. Open days are held as are flag-raising ceremonies. Some Posts also use World Post Day to reward their employees for good service.

For countries participating in the UPU International Letter-writing Competition for children, national winners are often honoured on 9 October.
