Every day thousands of people are trying to trace cell phone numbers for free.

If you are curious about who has been calling your teenage daughter or you suspect you spouse of having an affair, then you may be tempted to run a reverse cell phone lookup.

Here are some simple steps you need to follow:

Go to Google, MSN or Yahoo and type the number you are looking for into the search box. It would be better to put it inside quotes, in order to get more relevant results.

You can try many different formats like putting dots, dashes or spaces between the digits (for example you can try typing [555.555.5555] or [555 555 5555].

Many people list their numbers online for business purposes, so if you are lucky you may be able to find out the identity of the caller.

Unfortunately, there are no free directories you can use, because such a thing is virtually non-existent. In the vast majority of cases these so called free websites simply redirect you to a paid site.

If nothing else works then the only option you have left is to pay for a professional service. There are many legitimate companies on the web that can give you access to information, such as:

• The caller's name
• Their issuing location
• Possible neighbors and relatives
• Their household members
• Other numbers belonging to the owner.

You can also gain access to other confidential data like: their social security number, birth certificate, vehicle owner records, criminal and divorce records and many more.

The great thing about these websites is that they allow you to run an initial lookup without asking for a fee, so before paying them anything you can make sure that they have what you are looking for in their database.

These companies offer unlimited searches for whole year and can guarantee you 100% confidentiality.
