Who can register a .cpa domain?

Who may register

Restricted to licensed CPAs and CPA firms, verified with the AICPA.

What it costs

No price for .cpa in the table we track (Porkbun). That means we have no figure, not that the extension cannot be bought — several restricted extensions are sold only through accredited registrars in their own country, and some are not sold to the public at all.

Is a .cpa name free?

Availability comes from the registry itself over RDAP, with a WHOIS fallback where a registry publishes no RDAP service. A throttled or unreachable registry is reported as unconfirmed rather than available. It is the one wrong answer that costs somebody money.

You can check from a terminal or from an assistant instead:
