Is it possible to confirm if someone is enrolled at a particular school? So I know there's roadblocks like FERPA (this is in the United States by the way), but if I already knew:


Full Name
Date of Birth
Name of school (obviously, since I'd have to know who to ask)
(Supposed) Major


Would a college/university be able to confirm or deny that the student is enrolled, since I'm only asking to have information I already know confirmed or denied, and not asking for any new information? If so, which office/department at a given school would I (generally) direct a question like this to?
In the US, under FERPA, institutions of higher education (rules are different for K12 education) are required to define what pieces of information about a student are "directory information."  This typically includes the name, address, and phone number of a student and may include other information such as the student's dates of attendance, major, and any degrees that the student has been awarded.  The list of what items constitute directory information has to be made available to students, and students have the option of to keep this directory information confidential.  Other more detailed information (such as courses taken, grades, class rank, etc.) is automatically confidential and can only be released after an explicit waiver from the student.  

If a student has chosen to make their directory information confidential, then the university won't confirm or deny that the student has any connection to the institution.  if the student hasn't opted for confidentiality, then the registrar's office will typically provide the directory information when asked.  

There are good reasons for this protection.  For example, consider the situation of a student who has been the victim of domestic violence and is hiding from an abusive family member.  The abuser could call the university, talk them into providing the student's contact information and then use it to track down the student and harm the student in some way.  

On the flip side, this confidentiality provision can cause problems with reference checks for former students.  If a student chose confidentiality and years later an employer calls the university and asks "Did John Doe complete a BS degree at your institution?"  The institution would have to say "We can neither confirm nor deny this."  

In my experience, a fairly significant percentage of students (maybe 10 to 20%) at my institution opt for confidentiality of their directory information.  Given the problems that this can cause with reference checking, I'm somewhat surprised by how many students opt for confidentiality.  

In general, the office to ask would be the registrar's office.  They regularly handle requests from people who are conducting reference checks and background investigations.
