Since 1971, the UPU has encouraged young writers aged 9-15 to write letters on a given theme to win exciting prizes. The competition is an excellent way of making young people aware of the important role postal services play in our societies. It develops their skills in composition and their ability to express thoughts clearly. It also fosters enjoyment of letter writing and helps strengthen the bonds of international friendship.
The UPU's secretariat, the International Bureau, chooses a theme annually and publicises it. Participating countries then organize the competition at the national level through the Post, often with the support of the educational authorities and media. All entries must be submitted through the national Post. Each country chooses a national winner and submits them as the country entry to the UPU international competition no later than 5 May of the year in question.
