Got 2 calls from this number.  No message.  Im not going to call back either.  I live in MO as well, but not in that area code.

Got a call from here. Was just wondering who it was... I live in Missouri, but I don't like answering numbers I don't know. I mean, I have an iPhone, so I can block it just fine, but I need to know if I should unblock it, if it's important. I also get calls from (573) 882-9012, too. Does anyone know what these numbers are?

I got the same call... I also get a call from 5738845663.... Seems like some sort of scam to me.. I pick up and they disconnect.. probably someone trying to steal your information.. Who knows.... I'm searching for the answer also.

NIghtly call with no message at 7-8 pm....
guessing it is junk.
