If you have ever gotten a prank call or if you have even suspected your spouse to be playing games behind your back you would have wondered if you can reverse lookup cell numbers and if yes, how you should get started.
Private Investigator? A decade or so ago, the only possibility was if you hired a private detective.
Not only did they charge you $100s, but they also consumed many days-weeks before they found you the results.
However, there are much better options now, so don't even worry about private eyes.
National Cell Phone Directory? Unfortunately, such a thing does not exist.
This is because of mobile numbers are considered its owner's 'personal' information that cannot be shared with the world.
There are even privacy laws/acts that are in place to protect these rights.
They were going to build one in 2006.
Although there was initial agreement among the wireless companies, they later backed out of it after realising that they're risking their subscriber privacy.
White pages? Nope, that only has land numbers.
No cell numbers, no unlisted numbers.
Online reverse cell phone directories? Yes! They're your only option as of now.
They're specifically meant for cellular numbers and the best ones cover as much as 95% of the wireless numbers from the USA and they also give you a ton of information about the phone owner such as his/her Full name, Age, Address etc.
etc.
2 Useful Tips! Although there are a ton of these 'services' out there, all of them are not equally great.
Therefore it's highly recommended that you pay attention to the following two features when selecting a database.

1. Size - should have at least 210 million numbers, if not you're just wasting your time with a small database
2. Up-to-date - outdated data is inaccurate when it comes to cell phones.
   People change their numbers all the time.
