All you need for this is only the first 4-digit of the mobile number. In this Wiki page you will find all the mobile number series listed in a nice tabular column where they are categorized based on mobile operator and the zone (state/city). This Wiki page is updated regularly so as to provide up-to-date information on newly added mobile number series and operators. I have used this page many a time and have never been disappointed.
If you would like to use a simpler interface where in you can just enter the target mobile number and trace the desired details, you can try this link from Numbering Plans. Using this link, you can trace any number in the world.
By using the information in this article, you can only know “where” the call is from and not “who” the caller is. Only the mobile operator is able to tell you ”who” the caller is. So, if you are in an emergency and need to find out the actual person behind the call, I would recommend that you file a complaint and take the help of police. I hope this information has helped you!
