# faq
- ? How many .co.th domains are registered?
- There are 25,698 active .co.th domains as of October 14, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .co.th growing or shrinking?
- .co.th has grown by 24.78% over the last year (+5,104 domains).
- ? Where does the .co.th 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.th 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.
