CHE

The country code CHE is an ISO 3166-1 alpha-3 code for Switzerland, based on the Latin name for the country. Switzerland is officially called the Swiss Confederation, but because it has four national languages (German, French, Italian, and Romansh), the Latin name Confœderatio Helvetica was chosen for international purposes. The use of this Latin abbreviation is why the country's website domain is ".ch" and its alpha-2 code is "CH".
