# faq
? How many .science domains are registered?
There are 13,212 active .science domains as of October 15, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
? Is .science growing or shrinking?
.science has grown by 27.47% over the last year (+2,847 domains).
? Where does the .science 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 .science 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.
