The number is a legitimate out-going number for UCI Medical in Orange, CA. My husband has a new job there and, for me, he was trying to call me. If you don't have any medical business with UCI, this could be someone spoofing their number.
Is the number outgoing only? I tried to call them back, and I get a recording saying my call cannot be completed as dialed. I've redialed a couple of times and get the same recording each time.
Yes this is the number for UCI medical center. Listen to the message for a callback number. If they did not leave a message, then chances are it could be a collection call.
