Getting information about a mobile phone number used to be quite difficult unless you worked for the phone company. Public databases didn't exist for mobile (cell) phones until the mid-2000s. Now getting personal details such as the name, address, and mobile (cell) phone provider for a mobile number is as simple as typing in the number and clicking search. Although you won't always get results, in most cases you can get at least a name and address.
Find a mobile (cell) phone reverse lookup service. These services allow you to do searches on land lines and mobile phone numbers. A few to choose from include PeopleEngine.ws, Search Reverse Phone Number and Best People Search (see References).
Go to the website and type in the phone number. It will take about 30 seconds for the program to search its database. Once it's done, it will tell you the city that phone is registered in. It will also tell you if there are more details available. This may include the service provider and the name and address of the owner. The services are guaranteed with a 30- or 60- (depending on the service) day money back refund if you are not satisfied with the results.
