This number is one used by the state of Washington as a caller Id but they are actually calling from another at there office. They do not want the public to know there actual phone number do to harassment to them at there real numbers. other municipalities such as city employees also use this system.
Someone contacted us from Craiglist with a cat. They didn't pay up front and said they 'Forget their cats litter box." When they left they left the number above, and they have been gone for two about 4-5 hours. Interesting stuff.
Calls made to phone and when called back only a disconnection notice is given. Looked through a friend and found the general area of the calls are from Mt. Vernon.
