10 May 2018

LOS ANGELES – 10 May 2018 – The Internet Corporation for Assigned Names and Numbers (lCANN) today announced the release of the Final Proposed Draft version 4.0 [PDF, 486 KB] of Internationalized Domain Name (IDN) Implementation Guidelines. This draft is currently pending ratification from the ICANN Board of Directors.

The IDN Implementation Guidelines relate to the IDN registration policies and practices, designed to minimize the risk of cybersquatting and consumer confusion. Following the Call for Community Experts, the IDN Guidelines Working Group (IDNGWG) was formed in October 2015 to review the current version (3.0) of the IDN Implementation Guidelines, last updated in 2011.

While developing these Guidelines, the IDNGWG has interacted with the community to gather public feedback, as per the following details:

  4. Complete draft for Public Comment presented at ICANN58
  5. Final draft [PDF, 317 KB] for Second Public Comment released in December 2017
  6. Final draft for Second Public Comment presented at ICANN60

The IDNGWG has incorporated the feedback received from the community to finalize the Guidelines. Further details of the IDNGWG's work are available at the wiki page. The Final Proposed Draft v. 4.0 of the IDN Guidelines will be presented to the ICANN Board of Directors for approval.


ICANN's mission is to help ensure a stable, secure, and unified global Internet. To reach another person on the Internet, you need to type an address – a name or a number – into your computer or other device. That address must be unique so computers know where to find each other. ICANN helps coordinate and support these unique identifiers across the world. ICANN was formed in 1998 as a not-for-profit public-benefit corporation with a community of participants from all over the world.
