Tracing 800 numbers in the event of the company blocking their information and name was a very difficult process. The companies block their information purposely. However it is now possible to find out who is calling you from an 800 number that has been blocked. This can be done online using reverse phone directories.

A reverse phone directory is nothing but a collection of data that is unavailable in any other central location. It consists of all names and addresses that are attached to cell phone numbers. It also consists of names and addresses of 800 numbers that have been blocked and do not display a name on the caller id of the recipient of the call.

A reverse directory gives information on the basis of the phone number alone. When you access the directory and type the 800 numbers this reverse directory searches its entire database that has records of millions of numbers. It then returns all the information that is associated with the number entered. This can be viewed online.

Tracing 800 numbers is very essential when you want to know:
• Who is calling from the blocked 800 number
• What is the particular business that has been calling your home number again and again
• The names of the credit car and loan companies that are trying to reach you through a blocked number in order to collect some debt
• The companies who are calling you and the products and services they offer

Once the 800 numbers that has been blocked is traced you can take the desired action. The recipient of the call may decide if they want to speak to them, lodge a complaint for the harassing phone calls or send a request to fully stop the calls in the future.
