Everyday, thousands of people are searching for free reverse cell phone number directory. Most likely, you are one of them to have stumbled upon this article. Is there a truly free reverse cell phone number directory on the internet currently? Well, read on.

People use reverse phone directories for various purposes. They may be using the service to:

1. Expose the identity of prank callers

2. Do a background screening of someone they are hiring.

3. Find out who their daughters are chatting with every night.

4. Find who their spouses are talking to over so frequently and more.

Whatever the reason is, the internet has enables users to obtain instant information which used to take a lot of money and time to get. You can do a lookup on various numbers, from landline, toll-free to mobile and unlisted numbers. The first 2 categories are available on the public domains and online white pages. Hence they are free. However, when you are dealing with mobile and unlisted numbers, it is a different story. Why? Have you ever wondered how the reverse search service providers obtain their data for search from? Since these numbers are not on the public domains and mobile operators typically do not divulge their customers' information, data on unlisted and mobile numbers costs money. Furthermore, search providers have to constantly ensure that the data they are using is up-to-date information which adds an element of maintenance cost to it.

Although free reverse cell phone number directory may not be available, paid search on mobile numbers can be very affordable. A search on a single number can cost you no more than $10 and here is a useful tip, a good service will provide a free reverse cell phone number directory lookup and will tell you whether the number is found. This feature allows you to decide whether to pay for more detailed information instead of risking to pay for a search that returns no result.

Therefore, free reverse cell phone number directory does not exist but you can still go for paid services that are risk free and affordable.

Anyone who's spent any amount of time on the internet knows that of all the scams and broken promises that exist out there. Many sites will claim to offer free products or services in their ads, but of course when you get to the site it's either a complete lie or a very limited trial. Are backwards phone search companies sites from this plague that devours the internet?

We'll get to that in a minute, but first let's examine what exactly a backwards phone number search is for those unfamiliar with the process. Basically, it's the opposite of a traditional phone number search, in which you most often lookup a name to find out their phone number. With a backwards search you look up their number to find out their name, as well as other information like their address and phone carrier. This is useful when you've been contacted by an unlisted number or cell phone number, when you don't have call display, or when you otherwise have a phone number in your possession whose origins you're unsure of. This can prove useful when you've been out of contact with someone for a good amount of time and want to ensure the number is still theirs before making contact.

So when we talk about backwards phone records searches, we can break these down into searches of listed landlines, and those with listings of cell phone numbers and unlisted landlines. There are indeed many free directories which exist for the former, but the latter is where we begin to run into problems. It is actually illegal for anyone to freely distribute information related to cell phone or unlisted numbers in a database. So the answer to the title's question is both yes and no.

You'll have no trouble tracking down listed numbers for free through a backward phone book, but unlisted and cell numbers will not prove so easy.

All is not lost though, for there are sites which do host these numbers, but they aren't free, both for the legality issue mentioned above, and for the costs these sites incur gathering this data. Most of these sites charge a minimal one-time fee which gains you permanent access to the site. The fee is just enough to help offset their costs and make their service completely legal. What you'll get with these searches is the name, address and carrier information listed with that phone number.

Backwards phone records are collected directly from the phone carriers and is updated constantly. These sites will often list business and toll-free numbers as well, and some may even mention have pager numbers in their databases. These sites may also include access to other public records searches which can be of immense use, either directly through the site or through an affiliate or sister site.

You'll surely come across sites or ads claiming to offer free backwards searches of unlisted and cell numbers, but these will always lead to paid sites or simply be a big waste of time. Find a good paid site with accurate and current records and after that initial fee it will be as free to you as any other site out there.

When you've just received a call from someone you don't know and that number is either unlisted or a cell phone number, you'll probably want to do a backwards phone lookup. While listed landlines numbers certainly aren't a problem should you have call display, all other numbers will give you some difficulty, and it could very well be that the caller is counting on this.

Be it pranksters, bill collectors, a spouse's secret lover or other, hiding behind the veil of secrecy afforded them by having an unlisted or blocked number is their forte. Little do they realize that shredding that veil up and tossing it aside is now an easy task with a backwards phone search company.

For whatever you may need it for, a backwards phone records company can provide you full details on the owner of any phone number, be it a regular landline, unlisted landline, or even cell phone numbers.

First you'll need to ensure that you've found the right site. There are many different sites that offer backwards phone searches, but these may be restricted to listed landline numbers which won't do you much good in most instances. These numbers are available in many free directories and don't need to be paid for to access.

What you need is a site dedicated to cell phone numbers and unlisted numbers. These numbers are gathered through a much more strenuous process than the one that faces free directories. The numbers must be personally gathered by the individual company, as no databases of these records are kept. This requires manpower and money, which is why all legitimate sites dealing in these numbers will charge a fee. This is not to say that all sites charging a fee are legitimate, which certainly isn't the case, but rather that you simply won't find one of these directories for free.

If an unknown number has given you a call, or perhaps you have a number lying around with no name attached to it, a backwards phone lookup is just the ticket to solve your dilemma.

For listed landline numbers this normally isn't much of a problem. If you have call display these numbers will show up with additional information identifying the caller. These numbers can also be searched through in a number of free directories with decent results, though they may be outdated.

When the number is unlisted or is a cell phone number though, your options become a little less obvious. These numbers will not show in your call display with any information, nor can they be searched through at free databases. In fact hosting cell phone numbers in a free database is illegal, unless the owner of that number has given their permission for the company to do so.

You can overcome this by joining a backwards phone book site. These sites gather their data directly from the phone companies and service providers and offer the results to their customers for a small fee, making their service completely legal. These fees are usually one-time fees, and give you an unlimited number of searches for life.

Simply enter the number into the search box and you'll be instantly presented with the results, even more detailed than anything you could get through call display or other tracking methods. You will probably find yourself using it exclusively for listed landline numbers as well, for the amount of quality information they provide.

When two people are close, they tend to share everything with one another. Usually they enjoy the company of the same friends and partake in many activities together. Very few secrets are kept between such lovers, so it may become obvious to one partner when they notice their significant other being secretive or behaving strangely. For instance, you may grow suspicious of your partner if you notice they are making frequent calls to the same number over and over again, and it's a number you don't recognize.

What should you do? If you have a strong relationship built on trust, the first thing you should do is confront your lover if it is really bothering you. Do not use an accusatory tone, and pleasantly inquire as to who they are calling. You can be teasing and a little playful to show that you are not trying to be overbearing, just curious. Your partner, if they have nothing to hide, should understand your natural curiosity and should have no problem sharing the information with you.

On the other hand, if your lover gives an aggressive response or is not forthcoming with the information, you may feel that he/she has something to hide. At this point, there is no reason for you to continue the interrogation, instead, find out more about the number he/she is calling by using a reverse phone lookup for assistance.

You will need the 10-digit phone number, so you will have to obtain it from your call display or via another method if you do not have caller ID service. Once you have the telephone number, enter it into the query box of a reverse number search website. If no information is supplied free of charge, and you really want to find out who the owner of the number is, you can pay a small fee to conduct a more detailed investigation.

Remember that regardless of the information you may or may not find when you lookup a number bear in mind that you are breaking your lover's trust in you, and your partner will not be happy should they learn you went behind their back to check up on them. Therefore, you should think long and hard about running a reverse phone trace, and it should always be your last resort.

Prank calls and obscene calls are not to be underestimated and ignored. Although your phone provider can to some extent help you, they can't unscramble the person behind the call. You can trace the cell phone number and even the location. Okay you may be thinking about what if the calls are from a public phone booth. Do you want to know what booth and the person running it? Come on, you can at least give the booth operator a call to keep an eye on anomalous calls. Now how do you know who operates which booth? And even if the call is made from a regular cell phone, don't you wish to know the culprit and catch him red handed?

This is where the reverse cell phone search comes in to the picture. Reverse cell phones records is a huge database maintained by the authorized body which maintains the personal information for each and every phone number in the US. Personal information such as name, address, sex, age etc... can be found there.

Now, I have a story to share with you, last month my coworker, Michelle received an obscene call and she thought it was a prank played by one of her coworker. She's a single mom with 3 kids and this call disturbed her so much. She went and contacted her phone provider and got the number and the location of the call, but unfortunately the number was a public booth in Arizona. After hearing this, I took her over to the reverse phone search records and she found out the personal details about the phone booth operator and immediately faxed him a message about the issue. A day later she got a reply from the operator with a detailed information regarding the call duration and also about the details of a call the pranker made after calling her. She took that second phone number and did a reverse search and found out it was the pranker's friend and she phoned him, warned him and finally got the pranker's phone number and once again did a reverse search to find out it was a person with a history of prank calls and with many complaints. She logged a complaint on him and now she's happy. She never received a call like that in the following days.

It is easy to ignore the call and let it go and forget, but you need to take action and at least like Michelle did, file a complaint against the caller and let the government take the necessary action. Today who knows the pranker might be in prison because of so many complain logged against him. So make your complaint count and take action against these calls.

If you want to do a free unlisted phone number search, you should have known by now that it is virtually impossible to find one. How do I know that? Because I was looking for the same thing too. Is free unlisted phone number search really impossible? Must I really pay?

To answer that question, one has to first look at why do a reverse phone search in the first place. I am not sure about yours but basically people do searches on phone numbers mainly for the following reasons:

1. To stop prank calls.

2. To expose or verify a possible cheating spouse.

3. To investigate someone. Private investigators also use the service for their investigations.

4. To do a background screening on an individual before hiring him or her.

5. To locate a long lost friend. And so on.

The development of fiber optic technologies can be attributed to many scientists and inventors from all around the globe, spanning centuries. Each figure contributed his or her own ideas and applications, which has given us the advanced systems we use today for telecommunication systems, television transmissions, and data networks.

The basis for fiber optic communication can be originally traced back to a French inventor named Claude Chappe. In 1792, Claude Chappe developed the original semaphore system, which consisted of a series of towers, topped with semaphores that could convey messages from one tower to another. These semaphores refer to an optical telegraph system which incorporates the use of pivoting shutters to convey information through a series of 196 symbols.

The next development that can be traced to the development of these systems is the discovery of total internal reflection, a key modern feature. In 1854, British physicist John Tyndall discovered it was possible to guide light through a jet of water flowing from a reservoir. In 1890, inventors realized that the same principle could be applied to bent quartz rods, with the same effect. Practical applications of this process were then used in dentistry.

In the 1920's, scientists were attempting to transmit information and images through this medium. In 1930, Munich medical student Heinrich Lamm was successful in transmitting images through early forms of optical fibers.

Dutch scientist Van Heel successfully created the first cladding to be used with these bundles in 1954. Fiber cladding was a crucial innovation in this field. Modern fiber optic systems would not be able to function without cladding.

Modern optical fibers generally consist of three layers. In the center is the core. The core is where the light can be transmitted down the length of the cord. Surrounding this core is the cladding. The cladding serves a dual purpose, both protecting the total reflection surface from external contamination, while simultaneously retaining the light signal and greatly reducing cross talk between the cords. This cladding is then covered with a jacket, or sleeve, which serves as further protection.

Finally, in 1970, Drs. Robert Maurer, Donald Keck, and Peter Schultz of Corning Incorporated successfully developed a strand capable of efficiently transmitting quality signals, with little signal loss. This was the beginning of modern fiber optic systems.

In 1977, General Telephone and Electronics deployed the world's first live traffic fiber optic system. The system was deployed in a downtown Chicago area, spanning a distance of 1.5 miles and was used for telecommunication. Today, the fiber optic industry continues to grow exponentially in terms of both technology and application, and will continue to grow far into the future as better technologies are developed.
