This may already happen to you: There was an unknown incoming phone number on your cell phone's screen, or your caller ID. You wanted to know who the caller was and what the reason was? If the owner of that number called you several times, you may get nervous. You tried to call the number back and figure out who and why, but no one answered. So you got more nervous.

There is a solution which can stop your anxiety immediately. You can go to the internet, get your favorite search engine, and enter "Reverse Phone LookUp". In just a few seconds, you can find many sites offering reverse phone lookup services. Some of them even cliam their service is "free". What you need to do is entering the phone number directly. If the phone is a landline phone, you may immediately get the result and know who the owner of this number is. But if it is a cell phone, most likely you will only get the city and phone type (cell phone or landline phone). If you want to get more detailed information about this cell phone, then you need to pay for this reverse phone look up service. In a few minutes you will get the information of the owner: Name, address, phone carrier, etc.

Therefore, when a website mentions a "free" reverse phone lookup service, most likely it just provides a "free" preliminary search, i.e., it only includes the city and the phone type. And the user needs to pay for more detailed information. The user may even be able to get the comprehensive information about the owner of the phone number, such as criminal background, court records, neighbors, marital status, employer etc.

Most people don't want to pay and would like to search for free information. But it may be extremely time-consuming to search for actually free information, and sometimes you may get nothing after spending lots of time. Paying a small amount of me can save you much time, and get more accurate information.
