There are many reasons why you might want to conduct a reverse phone search:
•Find out the source of a harassing ("prank") caller
•Research a number that appeared on your phone bill
•Locate an old friend from high school or college
•Research "missed calls" on your caller ID that you don't recognise
•Verify an address
•And more
