The International Letter-Writing Competition for Young People (ILWC) is an annual global competition organized by the Universal Postal Union (UPU), a United Nations specialized agency, since 1971. Its published 2026 competition was the 55th edition, describing ages 9–15 with the date-boundary wording discussed below. Participants enter through national postal competitions. The 2026 competition partnered with the World Health Organization (WHO) and UNESCO.
How it works:
Each year, the UPU announces a theme and invites countries to organize national-level competitions through their postal operators, often in partnership with educational authorities. Students submit letters to their national Post, which selects a national winner. The national organizers forward their winning letters to the UPU International Bureau under an annual May 5 nomination rule; individual students must follow earlier or otherwise separate local timetables. An international jury evaluates the letters and selects overall winners and candidates that merit a special mention.
2026 theme: Write a letter to a friend about why human connection matters in a digital world. (Deadline closed.)
Prize:
For the published 2026 cycle, if conditions permit, the UPU sponsors the top winner and one accompanying adult to attend an awards ceremony, covering travel and accommodation. This is conditional prize support, rather than guaranteed funding for every entrant. Candidates that merit a special mention are also announced.
Purpose:
The competition develops students' composition skills, critical thinking, and ability to express ideas clearly. It fosters an appreciation for letter writing as a form of human connection, and raises awareness of the role postal services play in society.
Cycle checked November 4, 2026: The official UPU page explicitly says 2026 submissions closed and publishes the three winning letters. No 2027 theme, opening date, exact entry timetable or award-ceremony commitment was verified. January 2027 and a universal student May 5, 2027 deadline are not announced. The page’s annual May 5 rule concerns countries forwarding their national winner; local postal competitions have their own student instructions.
The 2026 Participants Guide limits letters to 800 words in the original language and requires letter elements, theme adherence and the relevant supporting entry materials. Its eligibility section says ages 9–15 and age 15 or younger on May 5, 2026, yet also expressly includes those turning 16 on May 5 or later while excluding earlier birthdays. Those age-boundary statements differ. Future age requirements remain unverified. No explicit universal entry-fee statement was located in the checked sources.
