Seriously, give us a clue. This isn't a free directory assistance service -- it's a web site which, by its own terms, collects information about unwanted calls so that we can share this information and help one another. You have provided no information to help or to share, and the best I can come up with quickly is that, if the number you reported is correct and is not spoofed, it is a cell phone number nominally assigned to Scotts Valley, CA. But there is, of course, no way of knowing whether the caller is actually located anywhere near either Scotts Valley or California.
Because no mobile phone carrier in the US provides -- or is even allowed to make public -- a directory of subscribers, the only thing you can do is either go to law enforcement to find out who is calling you, or search out the number on the Internet to associate it with someone or something or pay someone else to do it for you. Sorry!
