Registry Search Guide

Begin your search by using first and last name only. Then narrow down your results by entering in more identifiers for the registrant. If you know the county select the county by using the drop-down list. If you know the city or zip code enter that into the field then perform your search. There are more specific fields to use if you have that information pertaining to your search. Once you locate your offender select "Details" under the View Column. This will open a new web-page and list registrant information that is available to the public. If you are unable to locate a registrant please contact your local law enforcement agency for assistance.
