# faq
- ? How many .biz domains are registered?
- There are 1,358,503 active .biz domains as of August 31, 2026, according to DNSniffer's daily count of zone-file and certificate-transparency records.
- ? Is .biz growing or shrinking?
- .biz has grown by 34.78% over the last year (+350,563 domains).
- ? Where does the .biz 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 .biz 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.
