What is .biz?

.biz was delegated in 2001 together with .info, as an alternative to .com for businesses. The registry was launched by Neustar; its registry business is now part of GoDaddy Registry.

Who can register it

The registry agreement describes .biz as intended for bona fide business or commercial use. In practice registration is first come, first served through accredited registrars and no documents are requested at registration time.

WHOIS, RDAP and privacy

An RDAP service for .biz (rdap.nic.biz) is published in the IANA RDAP bootstrap file. OrbitProbe reads registration data from it first, as structured JSON: registrar, creation and expiry dates, EPP status codes and nameservers. For gTLDs, personal contact data has been largely redacted from public output since the rules ICANN introduced in 2018 in response to the GDPR. In most lookups you will see redacted fields or the details of a privacy service instead of a registrant name. OrbitProbe only ever shows the organisation name and country.
