So you've got this phone number you don't recognize.
It showed up on your caller ID, cell phone call log, or phone bill.
You aren't sure who it is, and you aren't not sure you care to talk to them.
But they keep calling, or leaving disturbing messages, and you need to find out who they are! If you use the right website to do a reverse telephone search, you can learn everything there is to know about that phone number:

• Who owns it
• Where they live
• Who their phone company is
• What type of phone the number goes with

Now there are plenty of free reverse phone search services out there on the Internet.
And they're great for what they do.
They can give you the name and address of a person or company that owns a typical telephone number.
But what about all that additional stuff like other phone numbers the person uses? Forget it.
Only the basic information is available through the free services.
And there's another problem.
The free reverse phone search services don't include unlisted numbers or cell phone numbers.
So it's a crap shoot as to whether the number you're interested in even appears in any of the free services.
To get real in-depth information about virtually any number, even those that are unlisted or assigned to cell phones, you need a different kind of service.
These gather information from many, many sources, and combine it into one giant database.
Because they gather their information from so many sources, these high-end reverse telephone search services can give you all the benefits I mentioned before, stuff that you simply can't find in free services.
You'll even get access to all sorts of information that isn't directly associated with the phone number.
Things like:

• Other phone numbers used by the owner of this number
• The names of other household members
• A map of their current address
• People search results
• Other public domain information related to the number

Even when the number is unlisted or assigned to a cell phone.
Are you still unconvinced about the value of this? Well don't fret.
The best companies in this space will let you run a preliminary search for free.
This search tells you whether or not the service has the information you need about the number, before you spend a penny.
If it doesn't appear that they have the information you need, you haven't lost anything except a minute or two of your time.
To top it off, if you do decide to do the full paid search and you're unhappy with the results, you can get a full refund.
It can't get easier or more risk-free than that.
