The main problem with phone books is that they do not allow you to search for cell phone numbers or unlisted numbers.
Also, phone books do not allow you to search if you only have a number.
Typically, you will need someones last name, a business name, or an address in order to find what you are looking for.
If you only have a cell phone number that you wish to obtain information about because you want to know who the person is or you want to stop that person from calling, an easy way to find out is with a reverse mobile directory.
A reverse mobile directory consists of millions of cell numbers, land line numbers, and unlisted numbers in which you can search in reverse.
By typing in the number, you can find information such as names, addresses, criminal records, warrant searches, etc.
When finding a reverse mobile service, be sure that the site is reliable.
Updated content is a crucial part of a directory and most companies will never update their site.
So be sure that you find a service that is updated.
The next thing that you want to look for is a no hit, no charge guarantee.
This means that if you do not find what you are looking for, you do not pay for the service.
Last but not least, make sure that the company offers a 60-day money back guarantee.
This will allow you to refund just incase you find out that you don't need the information.
