Information about Sex Offenders

Information about the sex offender classification and what the classification levels mean.

Sex offenders in Massachusetts must register if they live, work, or attend school here. You can search for a specific offender by searching their town or personal information. You can also search for offenders who are in violation of their registry. You can also see how many offenders are in your community. To request information about a sex offender, you can fill out a request form. Whether you can see an offender's information publicly depends on their classification level.
