Finding information about a cell phone number or finding out someone’s cell number via the Internet for free boils down to a process of first obtaining what information is readily available for free and then using that information to gain more details by systematically refining searches containing the data. Most look-up sites will give you nominal information for free and offer you more for a fee. Rather than paying the fee, you can use the provided information to track down what you are looking for. If you are looking up a number, the first thing to do is simply search for the number online and see what you get. You may find that someone has listed the number under his or her name on a personal or professional website or perhaps when answering an online ad. If your search returns results for similar numbers but not the exact one you are looking for, refine the search by adding quotation marks around the number. You can also try searching the number with various combinations of dashes, parentheses, spaces and periods in case it was listed in a certain style. If you still do not have the information you are looking for, take the search to other search engines. A good place to try is social networking sites’ built-in search engines. The search tactics remain basically the same if you are searching for a phone number for a particular name. You may try different types of queries, for instance “John Doe, phone number” or “Jane Doe, contact.” The idea is the same: You are trying to get specific information on a website by systematically refining your search criteria. Based on the information you obtained from the free look-up, you can refine your search by location and the person’s listed relatives. When searching by someone’s name, social networking sites are especially fruitful.
