# faq
- ? How many .tiaa domains are registered?
- There are 10 active .tiaa domains as of October 14, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .tiaa growing or shrinking?
- .tiaa has grown by 11.11% over the last year (+1 domains).
- ? Where does the .tiaa 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 .tiaa 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.
