# faq
- ? How many .aco domains are registered?
- There are 70 active .aco domains as of October 14, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .aco growing or shrinking?
- .aco has grown by 59.09% over the last year (+26 domains).
- ? Where does the .aco 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 .aco 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.
