To conduct an effective search, you must enter in the entire cell number, area code included, and if conducting an international search outside the NANP's range, including the international country code as well.

Using sites like this one, you can use cell phone numbers to look up not only the cell phone owner's name but also the name of their wireless carrier, whether the line is a business or residential line, and where the owner resides.
