When you register a domain name, ICANN (the organization that manages internet domain names) requires that your contact information be collected and placed into a publicly accessible database known as the WHOIS database.

The Problem with Public WHOIS Data

Because the WHOIS database is public, anyone can search for your domain and find your name, home address, phone number, and email address. This makes domain owners a massive target for spammers, telemarketers, and identity thieves. You may find yourself inundated with unsolicited emails offering web design services or, worse, scam emails pretending to be your domain registrar.

How WHOIS Privacy Solves This

WHOIS privacy protection (often called domain privacy) is a service provided by most domain registrars. When you enable it, the registrar substitutes their own contact information in place of yours in the public WHOIS database.

For example, instead of seeing your personal email address, a searcher will see a proxy email address provided by the registrar. If someone legitimately needs to contact you regarding the domain, they can email the proxy address, and the registrar will securely forward it to you without revealing your true identity.

Do You Need It?

In almost all cases, yes. If you are registering a domain as an individual or a small business operating out of your home, WHOIS privacy is essential for protecting your personal information. Many modern registrars now offer this service for free by default.

GDPR and WHOIS

It's worth noting that if you are a resident of the European Union, the GDPR (General Data Protection Regulation) requires registrars to redact personal information from the public WHOIS database automatically. However, for users outside the EU, explicit WHOIS privacy protection is still highly recommended.
