Switzerland’s three-letter FIFA code SUI comes from “Suisse”, the French name for the country, and has been used across World Cup competitions for decades. The team is popularly known as Nati, short for the German word Nationalmannschaft. Switzerland has qualified for 13 World Cups, reached the quarterfinals three times between 1934 and 1954, and has consistently made the Round of 16 in the modern era, arriving at the 2026 tournament on six consecutive appearances.
