# faq
- ? How many .co.tt domains are registered?
- There are 299 active .co.tt domains as of September 4, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .co.tt growing or shrinking?
- .co.tt has grown by 10.74% over the last year (+29 domains).
- ? Where does the .co.tt 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 .co.tt 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.
