Domain privacy (also known as WHOIS Protection or ID Protect) prevents the domain contact information from being public. It’s a great tool for students to protect their information.
You can see from the differences between the two pictures how domain privacy can mask who owns the domain.
When a student wants to transfer a domain, domain privacy needs to be turned off. Within the transfer process, the domain registrant receives a series of emails with a link to approve the transfer. The registrant must click that link in the email to approve. This won’t work if domain privacy is on the domain because the emails will ever reach the registrant.
