We researched over SIX online reverse cell phone number look up services and the top two services that we found are the following two. It’s almost impossible to say if one is better than the other. Some features are better with Cell Phone Number Registry (the largest database of 253 million cell numbers; updates every 15 minutes; and also provides a forward look up feature in addition to reverse look up). However, Reverse Phone Detective was the most popular service by far. It gets over 1.2 million visitors a month while the other only gets 55,000 visitors as of June 2009.

If you have searched the internet about Cell Phone Number Look up you already know that cell numbers are ‘UNLISTED’. In other words, they’re not published on free public telephone directories such as the white pages.

White Pages Only Have Land Phone Numbers - Unfortunately that’s the truth. This is because wireless numbers are considered ‘personal’ in contrast to land numbers that have always belonged to the public domain. That’s why you can find telephone directories for land phones in the form of white pages and yellow pages (for residential and business phones respectively).

The Good News - The good news is that thanks to these privacy laws, your ‘privacy’ is protected a whole lot more than you’re aware of. This is also the reason that you don’t get telemarketers bothering you on your mobile phone.

The Bad News - Obviously, the bad news is that when you want to do a cell phone number look up, you cannot do one as conveniently as you would have liked to. In other words you have no option but to use an online database that stores cellular phone numbers if you want to trace a cell number.

Online reverse cell phone directories - These are basically private databases maintained by different companies. These companies have built these huge directories of wireless numbers by collecting them from all 52 states of the USA. They also have cell numbers from all the wireless providers such as Verizon, US cellular, Sprint, T-mobile etc. etc. If they didn’t have mobile numbers from all companies out there, they probably wouldn’t be very popular because users would report them as incompetent services.

There are many reverse cell phone number look up services. Are they all equally reliable? - What do you think? Would you think all those xyz.coms out there would be as reliable as amazon.com if you wanted to buy a HDTV online? Similarly, when it comes to tracing mobile phone numbers too, there are extremely reliable and trustworthy services that have been in the game for as long as the reverse look up technology existed. And there are other smaller ’services’ that claim to be specialists yet no where near that.

How do you know which ones are good and which ones are not? - We have done all the hard work for you by comparing many of the services out there and narrowing it down to the top two. Both of them are extremely good. It’s not possible to say that one is better than the other because in some features Reverse Phone Detective outsmarts the Cell Phone Registry while with other features, Cell Phone Registry outsmarts Reverse Phone Detective. Both services are extremely reliable and they offer a 100% money back guarantee, so what have you to lose? If you’re not satisfied with the results, simply return it for a no questions asked full refund. That’s as simple as cell phone number look up can ever get!
