IMPORTANT: There are many companies offering Investigative Services who are NOT Licensed Investigators and are therefore operating illegally. Therefore be careful and demand that the company provide you with their License Number and then verify it through New Jersey at (609) 633-9352 or New York at (212) 417-5800; in PA you must contact the Clerk of Courts in the County where the company claims to be located.
