Domain Name Registrant Organization. The term Registrar means the entity that is authorized by ICANN to issue domain names. A domain name registrar must be accredited by a generic top-level domain gTLD registry or a country code top-level domain ccTLD registry.
Someone else has registered this domain under their own account at the registrar and are not willing to. Referring to corporate registrations if the Registrant Organization field lists the name of an existing legal entity that legal entity will be considered the registrant of the domain name. A domain name registry is a database of all domain names and the associated registrant information in the top level domains of the Domain Name System of the Internet that enables third party entities to request administrative control of a domain name.
The domain name registrant is bound by the terms and conditions of the registrar with which it registers its domain name for instance adhering to a certain code of conduct or indemnifying the registrar and registry against any legal or civil action taken as a result of use of the domain name.
Referring to corporate registrations if the Registrant Organization field lists the name of an existing legal entity that legal entity will be considered the registrant of the domain name. A registrar is the company that takes your registration request and reserves your domain for you at the main registry.

When a domain is registered the Internet Corporation for Assigned Names and Numbers or ICANN requires us to gather contact information for the person or business registering the domain name known as the Registrant or Domain Holder.
