Universal Acceptance

Universal Acceptance or UA is the concept that all domain names should be treated equally. Under it, all valid domain names and email addresses are accepted, validated, stored, processed and displayed correctly and consistently by all Internet-enabled applications, devices and systems.[1]

Many systems operate under the assumption that all domain names and their e-mail addresses are only available in ASCII, and that TLDs are restricted to a well-defined and constant two or three characters. The introduction of IDN ccTLDs in 2010 and the most recent wave of new gTLDs in 2013, however, greatly changed this dynamic.[1]

Domain names in a TLD must be useable in applications regardless of the written script, length or newness of the TLD.[2] The four main shifts spurring the need for Universal Acceptance:

  • Longer TLD Names: TLDs with names longer than four characters, such as MUSEUM.
  • Non-Latin based TLDs: Resulting from the addition of TLD names written in scripts other than ASCII, such as Cyrillic, Arabic and Chinese.
  • Rapid addition of TLDs: The New gTLD Program is spurring very rapid additions of long ASCII names and IDN names – as of 15 August 2014, there were 1,326 applications currently proceeding through the New gTLD Program.
  • International Emails: The introduction of non-ASCII names in email. While International Domain Names (IDNs) solved part of the ability to have non-ASCII names for servers, it doesn't solve the ability to have non-ASCII names for mailboxes.[3]

As the Internet evolved to be more personal, targeted and global, these assumptions are no longer valid. But limitations based on the old assumptions linger and now are preventing a larger and ever growing group of users from accessing the entire expanse of the Internet. In some instances, Internet users trying to use the newly delegated generic Top Level Domain (gTLDs), whose names may be many characters long and/or in non-Latin scripts, can experience "bugs" or the inability to access/register the sites.

This problem must be solved, and Universal Acceptance realized, in order to achieve a truly global, scalable Internet. It will be considered complete when any person can register and use a domain name in any top-level domain in widely distributed web browsers, email clients, in setting up accounts for Internet services and other services.

Universal Acceptance Steering Group

Universal Acceptance Steering Group (UASG)  is a community-led effort. It was formed in February 2015, and is tasked with undertaking activities that will target Universal Acceptance of all ASCII domain names, ASCII email addresses, IDN domain names, and IDN email.[1]

To submit questions or contribute additional material that may be helpful in overcoming these barriers, please send an email to GlobalSupport@icann.org with "Universal Acceptance" in the subject line.
