Since registrants’ contact data can change, registrars, such as GoDaddy, must provide annual opportunities for domain owners to review and edit their WHOIS domain data. According to ICANN’s rules, refusing to update this information, or providing false data, can lead to the suspension or cancellation of domains.
In addition, ICANN allows Internet users to file complaints if they discover WHOIS data that is incorrect or incomplete. In such instances, registrars must reverify or correct the data in a timely manner. Through such verification protocol, ICANN seeks to maintain the highest possible level of accuracy.
