A Search by Phone Number Can Tell You A Lot.

A cell phone number can provide several clues to people's identity and location, without you even having to conduct an in depth search. For example, an area code can aid you in honing in on the state in which the person resides, even the specific part of the state where the call originates.

But to find out a person's address with a phone number as your only clue, learning the state - even the city - where the call is coming from will only get you so far. That's when a reverse phone number directory comes in immensely handy.
