Who called from 3140000000

This number has called me 4 times in a hour. It's Sunday and this is the first day I've ever seen anything from this number. I added to my blocked call list through my service provider (Verizon).

I've gotten a call from this # but only a couple times in the past few weeks. Found out it was from one of my doctors offices that sends out those auto-mated messages to remind you of appointments. It was a new dialer system they switched to that doesn't use their office phone# but this stupid blank #. When I told them, they didn't even know about it.

If it is happening frequently, it is probably a scammer/telemarketer. If it is only once in a while, it could be a legitimate call from some office on an auto dialer. No idea about the STL Jail though. I don't know anyone calling from there. LOL

this is someone calling from St. Louis County jail.  It doesn't cost anything to take the call.

I keep getting them, and nobody talks, I hang up. It's annoying. Maybe a robot is waiting?

I have been getting them too for the last week  everyday at night???
