In Massachusetts, law enforcement services are divided between municipal police departments and county sheriff offices, each responsible for specific jurisdictions. The state operates under a multi-tiered law enforcement system where municipal police handle incorporated city areas while county sheriffs manage unincorporated regions, county jails, and court security.
Whether you are searching for non-emergency numbers, physical precinct addresses, or official portals for records requests, our database is verified to ensure you connect with the correct agency. Each county hub serves as a central clearinghouse for civil services, inmate rosters, and specialized law enforcement contacts tailored to the unique laws and jurisdictions of Massachusetts.

How to File a Police Report in Massachusetts
Determine Jurisdiction
Identify whether the incident occurred within an incorporated city (municipal police department) or in unincorporated county territory (county sheriff). Using the wrong agency will delay your report by 3–10 business days.
If in doubt, call the county sheriff's non-emergency line — they can redirect you to the correct agency without requiring a new report.
Gather Evidence Before Filing
Collect photos, video, witness contact information, serial numbers of stolen items, and the exact time and location of the incident. MA agencies are more likely to assign an investigator to well-documented reports.
Obtain Your Case Report Number
Always request your CRN immediately after filing — online or in person. This is your receipt and is required for all follow-ups with detectives, insurance companies, and records requests.
