Social media sites, such as Facebook and LinkedIn, are useful for finding classmates and others for free. Other options include sites specifically tailored for classmate searches, such as Alumni.net, Classmates.com, Batchmates.com and Friends Reunited.
With Alumni.net, a user can search by school as well as by name, and each institution has a directory. Classmates.com has a basic membership that is free. While the free membership does not offer access to all its tools, it still may be useful. Batchmates.com is based in India but has a worldwide membership. With Friends Reunited, users can also reconnect with friends from shared time in military service, clubs, workplaces or neighborhoods.
