The site also lists recent changes in relevant Massachusetts General Laws and other information and regulations for sex offenders. The site also lists Level 3 and Level 2 (if classified after July 12, 2013) offender information including photos, searchable by last name, community, county, zip code, incarcerated or violators, and provides numerical counts for Level 2 and 3 offenders by city, town, or Boston neighborhoods.

The website provides information on reclassification hearings, as well as information on waiving the registration fee for individuals who qualify as indigent.
