.ch is the Internet country code top-level domain (ccTLD) for Switzerland. It is administered by SWITCH Information Technology Services.
The ".ch" domain does not come from the name for Switzerland in any of its national languages; "die Schweiz", "Suisse", "Svizzera" or "Svizra". Rather, it comes from Confœderatio Helvetica (Helvetic (Swiss) Confederation), the Latin name for the country (all Swiss coins are also stamped with this name).
Registrations of internationalized domain names have been accepted since March 2004.
Since .CH enables you to protect your business online, a domain with .CH makes your web address unique and easy to memorize. A .CH extension is doing much more, helping you reach and communicate with the audience in Switzerland.
