# faq
- ? How many .us domains are registered?
- There are 1,774,980 active .us domains as of October 15, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .us growing or shrinking?
- .us has grown by 6.05% over the last year (+101,327 domains).
- ? Where does the .us 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 .us 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.
