The telephone, much like any other technological advances, can both be a convenience and a nuisance. This is because there are people who use it for more than just its intended use. The most common way that people use the telephone in a negative way is through prank calls. The more sinister ones even issue threats over the phone. Telemarketers are also considered among the most annoying callers. The sheer number of anonymous and unsolicited phone calls you receive each day may be enough to make you thankful for a free reverse lookup phone directory.

This directory is an online system wherein you can gather important information using a particular telephone number. You can identify the name of the phone number's owner as well as his address, among other information that are documented on his public records. If you keep getting crank calls with the same phone number reflected on your caller ID, for instance, you can use the reverse lookup phone directory to identify the caller or you may opt to report the incidence to the police and give them the phone number so they can look it up. They will run the number through the online directory and try to identify the caller from the information that they get there. They may then take action which will discourage the prankster from causing further harassment.

Another scenario where a reverse lookup phone directory may prove useful is if, for whatever reason, a telemarketer's offer sparks your interest. It will be to your utmost advantage to run their company's phone number through the directory so that you can ensure its stability and credibility before you get into any kind of transaction with them. With the reverse lookup phone system, you will gain access to the company's existing public records, which will include certain documents that reflect their financial capabilities and track record in the business that they are involved in. In this way you can avoid falling victim to any scam artist who is just out to get your money.

Just like any other gadget or tool, the reverse lookup phone directory does have its weakness. Primarily because it provides information based on an existing phone number, you will of course have to obtain the phone number of the person or entity whom you wish to lookup in the system. Unless you have that piece of information to start with, the reverse lookup phone system will be practically useless to you. A point in fact is what happened in the State of Virginia where residents were threatened by hoax cell phone text messages which they were randomly receiving. No matter what they did, they were unable to extract a phone number for the sender of the messages, so the police were not able to do anything and they were unable to use the online reverse directory because they had no phone number to work with. All in all, as long as you have a phone number, the reverse directory can be a huge help in times of need.
