I suggest this reverse phone lookup service: http://reversephone.toptips.org
It's a cheap service that works great!
It could be used for a much deeper search. You can use it to get hold of different varieties of background reports, and in addition cell numbers, addresses and names..
you can get unlimited reports... I ran with this because I required to verify more numbers. You can get the name, other phone number, address history, relatives, and much more about anyone!
The completly free reverse phone lookup generally doesn't provide anything interesting. To get interesting information, money will must be paid. The free searches don't provide considerably more than what may be found through the phone directory.
The reverse phone detective search tool does work, but you should use just the service that I posted above. The last thing you want to do, is pay for a service and find the numbers you want to lookup are not available in their directory.
The service that I reccomend doesn't have any kind of problem , you won't get any bad surprise!
