.radio TLD stats

• Run by Digity, LLC
• Sold most by COREhub, S.R.L., 55.7% in January 2025
• Our model compares it with 4 strings in the 2026 round

Names on the books at the end of each year since general availability, from the registry's monthly reports to ICANN, through May 2026. The marked point is the zone count of 23 Oct 2026, a different count taken on one night.

In its first year, to October 2018, 18 registrars held 10 or more .radio names and the largest held 52%; by its eighth, to October 2025, 19 did and the largest held 57%.

Year 1 starts at general availability and each year is labelled by the month it ends. Registrars with 10 or more names and the largest registrar's share are read at that month. A year with fewer than nine monthly reports is left blank.

COREhub, S.R.L. held 55.7% of .radio names in January 2025; the largest five together held 79.3%.

Shares add to 100%. From the registry's report for January 2025.

When we scored the 2026 round, our model listed .radio among the closest 2012-round TLDs for 4 applied-for strings. No applicant made these comparisons; strong and moderate are how close it judged each match.

Cross-checkThe registry reported 2,983 names for Jan 2025; the zone on Oct 23, 2026 held 69 fewer. The two are counted differently and 21 months apart: a registered name that is not delegated never appears in the zone, and a zone file is read on one night, a report at a month's end.

Counted from the registry’s own zone file on the night of Oct 23, 2026. A zone count is not domains under management: a registered name that is not delegated never appears in the zone, and a name on hold leaves the zone while it stays registered. The two numbers will not agree, and neither is wrong.

Names under management at month end, as the registry reported it. Reported to ICANN monthly. Sunrise Aug 2017 to Nov 2017; general registration Nov 2017.
