If you want to find out the email address of some person, who may be one of your old client, or a school friend or someone who has scammed you and you are looking to report fraud by finding his email address. Before you hire a detective to help you out in finding someone’s email address, why not become a self-detective to some extent. Here are some ways to find out.

Search Engines : You can google the name of the person, along with the location or his company name, ie whatever details you have. Google is the best search engine and you can try to use these kind of queries for getting better results.

You can find many results and if you surf through the top results you can either find some websites related to the person or some pages where his contact details would be listed, you can also try out the same option with the other search engiens like yahoo.com, live.com, ask.com etc. If this does not work out try out the next option.

Social Networking Websites : You would have heard about orkut.com , i know 80% of internet users have a idea about orkut.com and most of them do have a account with orkut.com which is a place where can stay connected with their friends and update each other. They can even build their networks by finding friend’s friend’s in a chain system and boast before their friends with their total friends count. you need to find the search box in these social networking websites and make searches the same way you made in the search engines. Not only orkut.com, but you can make a search at facebook.com, friendster, classmates.com and myspace.com
