.ch is the country code top-level domain (ccTLD) for Switzerland in the Domain Name System of the Internet. It is administered by SWITCH Information Technology Services.
The domain ch derives from Confoederatio Helvetica (Helvetic Confederation), the Latin name for the country, which was used because of its neutrality with regard to the four official languages of Switzerland. CH is the ISO 3166-2 code for Switzerland and also is used on vehicle plates.
Second-level domain names must be at least three letters long. Two-letter subdomain names are restricted to the Swiss cantons, as well as the domain ch.ch of the Federal Chancellery of Switzerland. The only exception has been the former domain of the Expo.02 which was held in Switzerland, www.expo.02.ch.
Registrations of internationalized domain names have been accepted since March 2004.
The Federal Office of Communications (OFCOM) has begun registering .swiss domains as of 7 September 2015. This is meant to augment the traditional .ch TLD. Applicants must currently have a "registered place of business and a physical administrative base in Switzerland" to apply.
