If you are looking for old school friends to organize a reunion, or searching for a long-lost relative to get back in contact, background checks can help narrow down your search. They can also be used to check the histories of those who are entering yours or your loved one's lives. Another use case is checking to see if someone is a real person to avoid romance scams, potential fraud or phony purchases and sales. You can also use a background check service to see what information is available about yourself.
