Internet could get one-letter gTLDs (but there’s a catch)

ICANN is set to loosen up its restrictions on single-character gTLDs in the 2026 application round, according to draft Applicant Guidebook language.

But the exemption to the usual rule applies only to gTLDs written in one script — Han, which is used in Chinese, Japanese and Korean.

Applied-for Latin-script strings must be three characters and over (because two-letter strings are reserved for ccTLDs) and internationalized domain names in other, non-Han scripts have a minimum of two characters.

The exemption for Han is being put in place because it’s an ideographic script, where a single character can have a meaning that other, alphabetic scripts would require an entire string to express. Google tells me the Chinese for “water” is 水, for example.

The 2012 gTLD application round did not feature the Han carve-out, and no IDN gTLDs currently in the DNS have fewer than two characters.

The draft rules governing IDNs are expected to be part of the next batch of AGB components that ICANN releases for public comment. The comment period on the first batch ended this week with no particularly controversial issues emerging.
