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. , there are 17 registrars.

  • : Taiwan in traditional Chinese characters (DNS name: .xn--kpry57d)
  • : Taiwan in simplified Chinese characters (DNS name: .xn--kprw13d)

Since at least November 2015, 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.
