.tw is the Internet country code top-level domain (ccTLD) for Taiwan. The domain name is based on the ISO 3166-1 alpha-2 country code TW. The registry is maintained by the Taiwan Network Information Center (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.

The current reseller registrars are as follows: Chunghwa Telecom, Chunghwa Int'l Communication Network Co., Ltd., FarEasTone, Taiwan Mobile, Asia Pacific Telecom, PC Home, Net-Chinese, TISNet, IP Mirror, Webnic, Neulevel.

Registering .tw website domains[edit]

Internationalized ccTLDs[edit]

ICANN assigned two Internationalized country code top-level domains (IDN ccTLDs) for Taiwan on 25 June 2010:[1]

Presently in November 2019, and since at least November 2015 ("IETF dnsop WG mailing list".), the simplified suffix is a DNAME alias for the traditional suffix. As a result any subdomain of the traditional xn--kpry57d TLD automatically has a CNAME alias from the simplified xn--kprw13d TLD. The traditional suffix is in active use.

Second-Level Domains[edit]

Registrations under .tw are possible in second-level space or under various domains as third-level domains:

  • edu.tw: for educational and academic institutions
  • gov.tw: for agencies of the Government of the Republic of China, operated by Taiwan
  • mil.tw: for the Republic of China Armed Forces, operated by Taiwan
  • com.tw: for companies or firms (Taiwanese or foreign) registered under the laws of their country
  • net.tw: for network or telecommunications license holders
  • org.tw: for non-profit organizations (Taiwanese or foreign) established according to the laws of their country
  • idv.tw: for individuals (must verify their identity by e-mail)
  • game.tw: unrestricted (but registrant must verify their identity by email)
  • ebiz.tw: unrestricted (but registrant must verify their identity by email)
  • club.tw: unrestricted (but registrant must verify their identity by email)
  • tw: unrestricted

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.


As of March 2017, around 8.31% of the .tw domains are served via secured HTTPS protocol, with the cPanel, Inc. Certification Authority being the most popular SSL certificate.[2] Apache is the most popular web server, serving 47.60% of the .tw domains, followed by Microsoft-IIS serving 20.31% of the total .tw domains.[2]
