Every month you browse through your bill you are stumped by that unknown number which keeps on showing up.
You check everywhere from your address book to your notes but you end up with nothing, which makes you ask more questions.
If you really want to know the name behind an unknown number, all you need to do these days is hook up your internet connection, go online, and run that number in a reverse cell phone lookup service.
Not too long ago, the only way to lookup or see who owns a particular mobile number is by having access to a top secret government database.
You could also try search engines and public phone listings, but even if you're lucky (which really doubt), the data you will get is old or useless.
If you want to waste a few hundred dollars you can always hire a privarte investigator, but if you don't, all you have to do is use reverse cell phone lookup and you will instantly get important, accurate, and up-to-date details on the identity of a number who has been bugging you.
It may be from a prankster, or an old colleague, or God forbid your spouse's best girl.
At any rate, you will know, and you will be prepared from the information that you can collect on what you need to do next.
It may not give you the complete picture, but it will certainly point you to the right direction.
The next time you ask your spouse a question by mentioning the name behind a number you've found, you will know for sure if he's lying or not.
