We can use telephone directories or call telephone help center to find the name, address or location of any landline number. But as far as mobile phone numbers are concerned, TRAI (Telephone Regulatory Authority of India) made it very secure and instructed all mobile phone operators not to reveal any mobile number informations related to user’s identification. It used to be almost impossible to track or trace any mobile number to find the owner, location or address details. But finally there are web services to help us in getting these top level personal informations. This technology is called Reverse phone Lookup.
All you have to do is get the mobile number and enter it. Reverse phone lookup site will automatically search for the informations related with that number and will display the complete names address and location of that number. This service is completely free. You can refer to this, this, this, this, this or this site tolookup any mobile phone informations.
However, keeping the privacy of people in eye, these sites should get banned. Mobile phones are known as private gadget and the informations related to the user should not be available to public. But since these sites offer mobile phone user informations, you can feel free to trace any mobile phone location, address details, name etc and that to legally.
