.tw is the Internet country code top-level domain (ccTLD) for Taiwan (Republic of China). The domain name is based on the ISO 3166-1 alpha-2 country code TW. The registry is maintained by TWNIC, a Taiwanese non-profit organization appointed by the National Communications Commission (NCC) and the Ministry of Transportation and Communication. Since 1 March 2001, TWNIC has stopped allowing itself to sign up new domain names directly, instead allowing new registration through its contracted reseller registrars.
