I received a call from this number last Friday(10:48am) and today, Monday(11:10am). My phone was turned off because I was working. This number is from Belfair, WA near Port Orchards, WA(not far from the navel base at Bremerton, WA). I called the number back during my lunch break, and a recording advised that this number is no longer in service.
I would guess someone, likely a collection agency or telemarketer, has hacked their phone to generate this ID, as they don't want the people they are calling to know who they are. I'm going to take time out tomorrow between 10:45-11:15 and await their call. I will report back the results of that conversation.
