I'm GUESSING it's the University Center for Survey Research. It's a Charlottesville, VA number, so that fits, and "Survey Research" is the only Center of S in the UV directory.
Called # back and young lady answered and asked me who I was. I asked her back the same question as the number had juste called me. She said no one had called from that # in at least a day, so it was not them. She was polite and seemed sincerely honest. I let her know someone was likely spoofing her number with the id UV# Center of S and that they should report it to the FCC
