Sex Offender Registry Board (SORB)

The Sex Offender Registry Board promotes public safety by educating and informing the public to prevent further victimization. We register and classify convicted sex offenders according to their risk of re-offense and the degree of danger they pose.

Who we serve

We serve the public by maintaining a website of Level 3 sex offenders, and those Level 2 sex offenders classified after July 12, 2013. The website allows members of the public to identify sex offenders living, working, or attending an institution of higher learning in the Commonwealth. The public can also obtain information on Level 2 and 3 offenders at their local police department, or by contacting us directly.

Interpreter services are available free of charge. When contacting SORB, please notify staff of your preferred language.  We provide a Language Identification FlashCard to assist you in identifying translation services.
