To find college friends for free, a colleague can visit her former school's alumni center and ask for the current information for the person she is trying to locate. Searching for classmates on social media sites, such as Facebook.com and LinkedIn.com, is also helpful.
One may also search for classmates using digital telephone books that are available at local libraries. If a former classmate is in the military, active-duty military databases are a good resource for locating members of all branches. If a former classmate owns property, an individual may also search property tax records that provide addresses and phone numbers of property owners.
