If you want to know the phone number of a person you will use a phone directory. A reverse cell phone directory is a directory that allows you to search a database for an owner's details and private information by entering their cell phone number.
First the service itself is a bit expensive and tends to take longer to find the results you need. This is the process of locating or discovering the owner of a mysterious phone number. Once you have established that you have a landline phone number, you can go to any white pages that you find online to see if they have a reverse white pages search option.
Reverse phone directory is very useful if you want to trace prank or threatening calls. Different people or companies often provide them with the information they gather for your convenience. It is not necessary that the reverse cell phone directory might be able to find a name always for the number you have provided, but yes, most of the time they will be able to pull up a name and other details.
I hope I've shown that online residential phone number search programs will be easier to use than the normal paper phone directory, that they are just as trustworthy and might even provide more information than the local directory. Good luck with your investigation.
