Don't worry, a potential name match does not mean you have a criminal record. Unfortunately, even if you do not have a criminal record, you can still flag a potential name match on the central index of names. We do not get any specific details as to why your name has flagged a potential match, other than it has done so.
Once your name and details are put through the system, your name is checked against a central index of names of people who have historical police information. If your name flags a potential match this means that it is the same or similar to one on the database. Your details are then referred to the relevant state police force, and they determine whether you are the same person on the central index of names or not, and whether there is any relevant historical police information that can be released.
