In the U.S., almost all registrars offices now just use the National Clearinghouse service. Many schools will simply refer you or your browser to their site. They also track student enrollment, so if you are a company paying for somebody to go to school and want to verify it, you can, or if somebody claims they are close to finishing you can verify enrollment through the Clearinghouse.

Attending university is one of the biggest regrets of my life. I'd rather find a different job than have to have any contact with that scam world again.
