.tw is the Internet country code top-level domain (ccTLD) for the Republic of China (Taiwan). The domain name is based on the ISO 3166-1 alpha-2 country code TW. The registry is maintained by TWNIC. Registrations are accepted by commercial registrars. Neulevel has entered into a partnership with TWNIC to market the tw outside Taiwan.
ICANN assigned two internationalized domain names (IDN) for Taiwan on June 25, 2010:[1]
No registrations under these domain have been conducted as of August 2010.
Registrations under tw are possible in second-level space or under various domains as third-level domains:
Domain names in Chinese characters may also be registered at the second level. Furthermore, any registrant of a standard domain name who has chosen a domestic registrar may automatically get two more domain names in Chinese characters in the following second-level domains: 網路.tw, 組織.tw and 商業.tw. These second-level domains correspond to net.tw, org.tw and com.tw, respectively.
