Looking up the owners of a cell phone number is such an easy thing to do – it is no more complicated than looking up the owner of landline or even business numbers.
You just have to perform a wireless number search with a slightly different type of phone directory than the one you would use to search the owners of landline and business numbers.
It really doesn't get any more sophisticated that.
Whereas business and landline numbers are publicly available numbers (as long as the owner of the number chose to be included in the phone company's free phone directory), wireless numbers are not publicly available. So the bottom line is that if you want to find out the address and name of a certain unknown cell phone user, you are going to have to spend a small amount of money because this information is privately owned.
To put things even simpler: let's just say you want to search the owner of a Verizon mobile number. The first thought in your head to get this job done may be to get on Verizon's website and perform your search there. But companies like Verizon do NOT provide a public phone directory to the public for the cellular numbers they own, maintain, and service.
So, you have to take your search some place else.
And the place you take your search to is a wireless number search directory. This type of telephone directory actively collects and distributes owner information reports for just about every type of telephone number you can think of – not just mobile numbers.
What this means is that some searches will cost money, and others will not.
Landline and business searches are free (provided you purchase a membership with one of the more reputable reverse phone directories), but a report connected with a reverse cell phone lookup is always going to cost a bit of money because the directory (in order to provide the most accurate and recent personal information possible) is constantly purchasing this information from cellular carriers like Sprint, AT&T, Verizon, and whatever other mobile carrier you can possibly think of.
And the report you will obtain from a directory such as this offers reports that are filled with much more personal information than you will find in a basic report (name and address) furnished by the free public phone directories. So, if you would like to find out a list of past addresses, relative names associated with a particular unknown caller, occupation, age, or other similar personal details such as these; you will have to perform your search with a paid reverse phone directory.
That's just about you need to know about the basics of looking up the owner of a cellular number. A few other things to keep in mind are (a) to make certain the phone directory you decide to perform your first search with offers a way for you to easily recover money spent on reports that did not live up to what was promised; and (b) to make sure to perform your wireless number search with a directory that constantly updates its database.
