Most of the authors for these sites are affiliates with the professional services and generally will not admit that you can conduct most of your reverse phone lookups for free -- when using the correct online tools. Free reverse lookups for the White Pages and Yellow Pages exist, but these services do not exist for unlisted numbers.
The White Pages and Yellow Pages companies generally will provide reverse lookup services for free -- online. Yellow Book actually hands out and delivers these services for free to most mailboxes in the United States -- for their nearby counties and communities. So, it is only natural that you could conduct a free lookup for other counties as well. There are many sites that provide these across the whole continental United States. Here is a list of multiple, popular sites that provide free reverse lookups:
-Addresses
-Any Who
-White Pages
-Info Space
A professional reverse lookup is generally used when all else fails; in this case, when trying out all of the free services fail. One of two conditions is usually met when a free service fails: either the phone number is unlisted or it's a cell phone number. Generally, the best thing to do is to compare the professional services with a single site (i.e., see last paragraph). And usually, most of these professional services will give you your desired information instantly or in a couple of hours. And if you feel that other people may conduct a lookup on you, most of these professional services will also allow you to remove your personal information (phone number) from online databases and phone records.
The Reason for a Reverse Phone Lookup is to find the owner and address of an inputted phone number. It can be a very serious issue when you receive calls from unknown persons -- possibly just a prank caller or possibly a stalker. Other reasons for these services can range from relationship trust issues or to just knowing that who is the one that left a message on your machine -- but forgot to leave their name or their address.
At last the conclusion is that always check the free lookup services first, and then the professional services. Many of the professional reverse phone lookup services will generally allow you to subscribe for a membership plan that will give you access to unlimited phone lookups -- this is a fairly cost-effective way of obtaining reliable information on any phone number.
