The Wisconsin Department of Corrections manages the state’s Sex Offender Registry, which requires individuals convicted of certain sex offenses to register and keep their information current. Registrants must provide details such as name, address, and offense, and are obligated to report any changes so the registry remains accurate. The registry is updated regularly and is accessible to the public through the DOC’s online database.
