<human>: A friend of mine is being harassed by an unknown number. And we are trying to figure out who it is, based on the texts it is someone she knows and the person sending the texts obviously knows a lot about her. 
 -We know the number is from the area based on the area code and found out the cell phone carrier. Without using the websites like reverse look up, is there anyway to find out who this is? 
We have asked around to see if anyone knows, and not one person seems to have the number or know who it is. 
Yes we know, block the number, all we need to know is who owns the number.

Would anyone be able to help out here?

Can you give me a shortened version of the text?
