There is nothing you can do, this is a phone card number. My wife is in korea and this number came up when she called me. This is what is happening, koreans are getting this card which uses a number in Oregon. The card uses this number becuse it gives the person that uses the card more min. They use this becuse you cant trace the call to them. This is no where near my wifes number so when I asked her why this number was comming up she told me about the card. You cant call this number and expect a responce. There is nothing you can do other than block the number. This is a good scam becuse of the fact in order to report a number it has to belong to someone, it doesnt.
its is when someone from korea calls you. Sometimes this is the number that comes up, probably the switchboard it connects to when it is routed to amercia. i am certain of this, as to which korean is calling you, who knows, mine was my gf.
