There are lots of reasons you might want to do a background check. Maybe you're in charge of a membership list that has outdated information and you need to track down the new contact details for a few people. Or you might be curious about your new neighbors and want to get some insights before you reach out (though, honestly, that might be a little creepy!). Background checks can also give you some peace of mind if you're into the online dating thing, to make sure that seemingly nice man or woman really is who they say they are before you meet in person.
