An 800 number is a special telephone number where the caller doesn't have to pay anything for the conversation, the charge for it is applied to the receiver by the phone carrier company.  It is called as free number not because it is entirely free and nobody has to pay but because of the fact that the person that initiate the call can talk for free on this number.



Most of these numbers have a purpose and that is to offer businesses a way to communicate with their customers. This is very useful especially for technical support services. These types of numbers are used also for selling. These numbers give the opportunity for different businesses to increase customer satisfaction by providing after sales support for certain products/services. These numbers are used also by different volunteer associations.



Having in mind this diversity of tall free numbers one has to find out who is at the receiving end (usually you find the number on a webpage, a newspaper, a street post, etc end you should know who are you calling to). If it happens to forget who is the owner of that number because you have jot it on a piece of napkin and you have not written the name, you could call that number, and always someone, or a prerecorded message (usually you encounter this on tall free numbers) would state their identity.

That is not so hard to do. If you hear a message like "Hello you have called to Blabla Company. How may I help you?" doesn't say much. It is obvious that you knew that you are calling that number and you knew what it does. What if you don't? You could ask? What businesses are you into? A bit awkward Isn’t it?
So there is a way to escape the embarrassment, to turn to internet phone directory dedicated to 800 phone number reverse lookup. Here are some of them: http://www.customtollfree.com/toll-free-reverse-lookup.html (has a simple user interface with a prominent search box where you could type the toll free number you would like to search for.). Another one is  http://www.anywho.com/ with an intuitive user interface. There are also other online phone directories http://www.internettollfree.com/800-number-reverse-lookup.html , . http://www.freesearching.com/toll-free.htm Let’s not forget yellow pages and white pages.

A little help from mighty Google - the "phonebook" operator used to search both the business and residential listings regardless of phone numbers you type into search box. You have a pretty big chance to find lots of information about that or a slim one to find nothing. Usually this toll free numbers are largely available to general public.



The other giant search engines MSN and Yahoo can also provide good results when searching for 800 phone number reverse lookup. You could use the old method if you find nothing on the internet, perhaps it is not indexed or that business does not have site, you could turn to printed editions of phone books, yellow pages, white pages, blue pages. The key question when you are receiving a call from an unknown toll free number is to ask whom am I speaking with? They usually would tell you before you even think to ask.
