Cell phone numbers are not handled in the same way that traditional land lines are handled.
With a traditional line, each number is registered to a public directory, and contains information such as the name and address of the person who owns that number.
Because it cannot move from one location to another, the address is considered a unique identification for it.
A reverse mobile number look up is a bit more complicated to find information for.
When it comes to mobile phones, the information may change in relatively short periods, and the vast databases of numbers are kept by each provider.
In order to do a reverse number look up, the database would first identify the general location, using the area code, and the find the mobile service provider by comparing the first three numbers of the mobile phone.
Once that is done, the last four digits will identify the precise person who owns the number, and you can then find out any information which may be available for that person.
With premium access, you will probably be able to retrieve addresses, but free access is usually limited ot only finding out the owner's name.
Now, a reverse number look up may not give you more than some very basic information.
Some phones do not require complete registration, while others have complete contact data on file, including the address and any other applicable information.
Much of this information may come at a price, or require a membership, though, to reduce malicious intentions towards unsuspecting cell phone owners.
