Uni Naming & Registry IDN Policies

All TLDs operated by Uni Naming & Registry (UNR) enjoy full support for DNS names in any language among the following:

  • Cyrillic (focusing on Russian primarily)
  • English
  • French
  • Italian
  • German
  • Portuguese
  • Spanish
  • Chinese (On a separate page here)

Support for these languages follows the most current policies and standards. The support is extensive and includes all of the services: WHOIS and other directory services, Domain Registration and DNS.

Note that English language support does not require the use of IDN, as domain names can be properly encoded using the default ASCII character set.
The following policy statements related to IDN apply to all TLDs operated by UNR:

  • All languages supported for this TLD use left-to-right scripts. Only characters with the L property set according to RFC-5893 can be used.
  • Name registration under TLDs operated by UNR is not subject to automatic reservation of “IDN variants”.
  • Registration of IDN labels must indicate the IDN table name being used and both the corresponding A-label and the U-label. All data must be consistent in order for the registration to be processed.
  • Please note registrations of Chinese IDN variants will be blocked automatically. Please email partners@unr.com if you have any questions.
