# faq
- ? How many .pro domains are registered?
- There are 1,221,821 active .pro domains as of October 15, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .pro growing or shrinking?
- .pro has grown by 183.63% over the last year (+791,037 domains).
- ? Where does the .pro 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 .pro 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.
