A registrar of record is the auDA-accredited registrar who is responsible for managing a particular domain name. Only the registrar of record is able to renew, modify or redelegate the domain name.
To find the registrar of record for a particular domain name, use the public WHOIS service.
Registrants are free to change their registrar of record at any time. For more information refer to auDA's Transfers (Change of Registrar of Record) Policy.
