Of course, cell phone numbers and unlisted numbers present a difficulty here. They are not listed in the phone book. This does not, however mean they can't be looked up. Though not in the public domain like a land line number, there is a way of finding out.



There are firms who are in the business of compiling lists of every phone number. Out of these lists, directories are built which hold every phone number that they can find. These companies pay for access to this information, which can then be searched to find out information on the owners of certain numbers.

These searches can be performed over the web on these directories. Known as "reverse phone directories" since they allow for lookup by number rather than by name, one just enters the number and allows the directory's search engine to handle the rest. The results, hopefully information on the number holder, will be displayed.

There is generally a cost to use these services, but don't fret. It's quite reasonable, and some sites charge a one time fee for unlimited usage of their database. If you think you may need this sort of service often, this will be the best idea for you - no need to pay a fee each and every time you need to look up a number in the directory.

This service can be useful for different reasons - you might want to "investigate" a phone number that keeps showing up on your spouse's phone or perhaps there's a number that keeps prank calling you. It's a good tool to have whenever you need to look into someone but only have their number.

Before going ahead and paying for a reverse directory search, there is a way to check for free. And what way is that? Google, of course. Just do a search on the number in case it is listed on a web page.

A paid search isn't terribly expensive, but Google is worth a try nonetheless. You may be surprised!

If this number can be found on the internet, Google will find it for you. Phone numbers sometimes end up on websites, in advertisements and so on. In these cases, you may just be able to find these numbers online.

You never know - if you do get a result from Google, the page may contain the information you want. If you strike out, then it's time for the paid directories.

It's amazing how much you can learn from just a phone number. You can find out all sorts of information about someone through one of these directories.
