# faq
- ? How many .sch.ir domains are registered?
- There are 119 active .sch.ir domains as of September 4, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .sch.ir growing or shrinking?
- .sch.ir has grown by 12.26% over the last year (+13 domains).
- ? Where does the .sch.ir 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 .sch.ir 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.
