Prank callers forcing you to leave the phone off the hook? Threatening calls have you upset and scared? Maybe you have found a suspicious number on your spouse's phone and want to investigate? The reasons for finding the owner of a phone number are many and varied and if it was a normal phone number it would be easy to a reverse lookup on the net but an unlisted phone number reverse look up is a different kettle of fish.

A phone number lookup is a simple thing if the service provider has a complete database, you simply enter the phone number into their search box and it matches it with a number it knows then returns the details of its owner, some even provide more information on this person but an unlisted phone or cell phone look up is harder because both unlisted numbers and cell phone numbers are not a part of the public domain where as ordinary land lines and the details of who owns them are a freely available commodity that any reverse phone number directory can get access to.

What you need is an unlisted phone number reverse lookup service that has a database of cell phone number and unlisted numbers and the details of their owners. These sites do exist on the internet because entrepreneurial companies have purchased peoples numbers and details off other a variety of companies who collect this information and compile all of these smaller databases of numbers into one mega database that you can use like any ordinary reverse directory.

Unlisted phone number reverse lookup services are also entirely legal as people who request their number to be unlisted are just like a cell phone number, they are not required to be publicly available but they are not protected by law to not be published. In this way their privacy is protected somewhat but when you need to know their details it does not stop you from finding out especially if they are doing something wrong!
