209 Area code is Fresno, California and vicinity. What I believe it to be is a marketing company. They know all the cellular prefixes and are seeing who picks up. I just use call blocking app and black list the number.
I got a call from this number Today May 12 2014 at 11.02 am....I have no idea who this person is. I missed the call and this person is not in my contact list. I seem to be getting a lot of hang up calls too.
