Frequent cell phone users will often experience receiving unknown phone call. When they tried to figure out who a phone number belonged to, they either found the owner of the number easily or extremely hard to do. This is because the numbers that you are investigating are unlisted in certain directories that you are relying on.
It is easy to find out the owners of the unknown numbers that belong to home or business, because these numbers are listed in most of the phone books or phone directories. Most of the online phone book directory will store these phone numbers because the information is free or it is accessible in the public domain website such as yellowpages.com. The service provider only needs to get the result from these public domains and add it to their database.
On the other hand, investigating the number which is either a cell phone number or a number that was requested to be unlisted in public domain is a headache. You will probably spend a lot of time sitting in front of the computer trying figure out who is the owner of an unknown number.
