Why shall I provide personal data?
When registering a domain name, you have to provide your personal data in order to verify domain ownership rights. This requirement has been set by ICANN, an international organization that coordinates the operation of the Internet Domain Name System. ICANN suspends domain names for which inaccurate or incomplete contact data are provided.
Why is it important to protect contact data?
Your name, address, email, and phone number are available to everyone, including hackers. They may use this information for illegal purposes, such as spamming, obtaining access to your account, and domain hijacking.
Why protecting your contact details is important
No third parties will have access to your details.
Protection from spam
Your email address and phone number will not end up in spammers' databases. But it will still be possible to contact you using changed Whois details.
Protection from domain hijacking
Attackers will not know your personal data and will not be able to use it for domain name hijacking.
