I had a call from this same number on the same date.  Caller ID states the caller is "Out of area", even though I am in the 618 area.  These calls that are ID'd as "Out of area" are always scam/nuisance calls, and I block all such numbers.

Also, I've had a more recent call from a number very close to this one, which is 618-803-4368, and it also came up as "Out of area", and originating from Alton, Illinois, a known hotbed of scam robocalls.
