## How .io is priced

1 of the 6 registrars whose .io pricing we have verified prices it flat — first year the same as every renewal — while the other 5 discount year one (median renewal 1.9× the promotional price). Verified renewals run $51.75 to $75.98 a year.

A flat seller and a discounted one can look identical in year one and differ sharply by year three, so compare the renewal or the multi-year total.

Computed from the 6 verified .io prices this site holds, not from every registrar selling .io.

## Registry facts (IANA-sourced)

- Registry operator: Internet Computer Bureau Ltd. (operated by Identity Digital)
- IANA root entry: https://www.iana.org/domains/root/db/io.html
- Registration restrictions: No nexus requirement; effectively open like a gTLD.
- DNSSEC: supported
- Notes: Renewal pricing is higher than .com because there is no ICANN price cap on ccTLDs. Treated as a startup-friendly TLD despite its formal ccTLD status.
