How to register

If you are required to register due to a sexual offense, you must do so annually.

What you need to Register 

If you are required to register in Massachusetts, you must register with the state sex offender registry every year; unless you are homeless, then you must register monthly. Depending on your level, you will need to either mail your registration information to the registry board, or go to your local police department in person to update it.

If you are an Unclassified or Level 1 offender, you will need to complete the Sex Offender Registration Form.

If you are a Level 2 or 3 offender, you will need to visit your local police department to update your information.
