Is there a National criminal record database?
Yes! It is called the National Crime Information Center (NCIC). However the system can only be accessed by law enforcement personnel. It is not available to the general public. If a company tells you they can check national criminals then beware there is no technology available at this time for that type of search. Here at Network Research Systems we have a proprietary database called M.A.C.E. (Multi Criminal Access Evaluator) which can check up to twenty states for criminal records and thirty three states for Department of Correction data. We use M.A.C.E. in conjunction with other criminal searches.
