Back in the days before the Internet, about the only people who had access to information about finding lost people were private investigators. Because the process they used was so labor-intensive, the private investigator needed to charge quite a lot of money to make a fair living when finding lost people.
Today things are far different due to the advancements in Internet search technology. It's amazing and almost scary to realize how much of our lives have documented and posted onto the Internet. Everyone should go to one of the search engines like Yahoo or Bing and type in their first and last name and just see what's out there about the them. It might very well be shocking to most of us to see how much information anyone can find out about us simply by going to any computer and typing in a short search.
But to find a person by cell phone number is a lot more difficult than finding that same person's landline number. The reason being is that the major telephone providers do not provide a listing for all the cell phone numbers that they give out. The reason for this is that cell phone traffic requires bandwidth which in turn requires money. Every cell phone call has a small cost associated with it to the service providers. Even though we may have unlimited calling on our telephones, each call still requires a bit of bandwidth and thus requires a bit of cost to the providers .
So to find a person by cell phone number becomes a bit more difficult. We must be a little more creative in doing our searches when looking for these people by cell numbers. To begin with, simply go to Yahoo or Bing and type in the person's name followed by their last known state or city of residence. It also helps to type in their career if known. For example, if they are a lawyer, simply type in their name, their city or state, and the word lawyer into the search string in either one of the major searching engines. If the person's name is quite common, this type of search can lead to countless pages, perhaps hundreds or even thousands of search results that must be sifted through.
This of course can be extremely time-consuming and to eliminate many of these unwanted results it becomes necessary to perform even more advanced searches. Most of the search engines have advanced search functionality by clicking on the "advanced search" button on their homepage. There you can filter the search further and eliminate many of the unwanted results. For example, if you notice a person has only been in a given city for a certain number of years, you can limit the number of years the search goes back for.
For example, if you know they have only been in Dallas Texas for three years at most, you can tell the search engine to eliminate all search results that originated with that person's name and address previous to the three years. Without performing this advanced step, you may in fact have results that go back 10 or 15 years for that person's name. Of course if the person's name is quite unique, you made fact only have a few pages of Internet search results to browse.
These steps should make it far easier to find a person's cell phone number. With patience, simple and free online searches can lead to that person in a short amount of time.
