I receive daily calls from 425-648-9456 with "Washington" as the Caller-ID.  Never a message.  Another board says that this is a police activity solicitation.

I get a call from this number every so often..who is it?

I just received a call from this number as well. I answered and he asked me if I was "the owner" a couple of times and then refused to tell me who he was and hung up on me when I wouldn't reply to his question.

I answered and heard a hangup click. Waited until it was disconnected ("if you want to make a call..."

I too received a call from this number.  I answered and there was a slight pause and then the caller hung up.

Perhaps the caller is paid to find out if numbers are being answered and then sells reports this to an advertising company.
