The Universal Postal Union (UPU) is excited to announce the 54th edition of the International Letter-Writing Competition for Young People, taking place in 2025. This year, the UPU is partnering with the International Maritime Organization (IMO) and the United Nations Educational, Scientific and Cultural Organization (UNESCO) to inspire young writers worldwide to reflect on the importance of protecting our seas and oceans.
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 that postal services play in our societies. It develops their composition skills and ability to express their thoughts clearly. It also fosters enjoyment of letter writing and helps to strengthen the bonds of international friendship.
Every year, the UPU’s secretariat – the International Bureau – chooses and publicizes a theme. Participating countries then organize the competition at national level through the Post, often with the support of the educational authorities and media. Click here to read the competition rules.
An international jury compiled by the International Bureau judges the letters and selects the overall winners and candidates that merit a special mention.
Theme for 2025:
Imagine you are the ocean. Write a letter to someone explaining why and how they should take good care of you.
This year’s theme addresses the significance of the United Nations Sustainable Development Goals (SDGs) and, specifically, SDG 14, which focuses on the conservation and sustainable use of oceans, seas and marine resources. Through collaboration with this year’s partners, the competition highlights the UPU’s mission to promote literacy and communication through letters, while aligning with the commitment of the IMO and UNESCO to address the urgent need to safeguard marine ecosystems. This year’s theme invites young participants to give voice to the ocean, exploring its beauty, the challenges it faces and our collective responsibility for preserving it.
By participating, young minds will be encouraged to reflect on their role in building a sustainable future, raising awareness of marine conservation and the interconnectedness of ecosystems worldwide.
