# faq
? How many .radio domains are registered?
There are 3,086 active .radio domains as of October 15, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
? Is .radio growing or shrinking?
.radio has shrunk by 37.86% over the last year (-1,880 domains).
? Where does the .radio domain count come from?
We ingest ICANN CZDS zone files and Certificate Transparency logs continuously and snapshot the per-TLD count once a day. A .radio domain is counted as active if it appeared in a zone file in the last 2 days, or - where no zone file is published - if a certificate was issued for it in the last 12 months.
