Each and every active domain is registered on the name of a person and during the registration process many details are introduced - the owner’s names, address, e-mail, contact number, and so on. This information plus the registrar company name and the registration/expiration dates is referred to as WHOIS of the domain and in agreement with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it needs to be current and correct. If a domain has incorrect WHOIS details, it might be reported and if the details are not corrected, the domain name could be deleted or the registrar company may take over its ownership. By default, the WHOIS details are public and can be seen on a lot of lookup websites, or for a limited number of country-code extensions - on the websites of the respective Registry companies. All businesses that offer registration services are obligated to provide an effective way for their customers to access and edit the WHOIS details of any Internet domain they own as much as the particular TLD allows it.
