The Massachusetts Criminal History and Your Own Copy
Massachusetts is one of the states that lets anyone look up another person's statewide criminal history: open access iCORI lets anyone request limited conviction information by name, for $25 a search, through the Department of Criminal Justice Information Services. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it. The search is on the Department of Criminal Justice Information Services site.
To see your own record, the route is a personal CORI request, free once a year online. The state page SearchSystems verified for it is at mass.gov/massachusetts-criminal-offender-record-information-cori.
Arrest Records Kept Locally in Suffolk County
The Sheriff’s Office, Suffolk County Sheriff’s Department and the agencies that report for Boston, Revere, Chelsea and Winthrop Town keep the arrest records in Suffolk County: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
The FBI's agency list also places 13 campus police departments, three other agencies, one state police unit and three state agencies in Suffolk County (the arrest records guide names each one); each keeps the records of its own arrests.
Together, the four agencies in Suffolk County with all twelve months of 2025 on file reported 9,323 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Suffolk County arrest records.
The Crimes Behind the Records: Suffolk County in 2025

Each reported crime is a report on file with the agency that took it, and each arrest that follows is the start of a criminal record.
The full crime section, agency by agency, is on the Suffolk County public records guide.

Asking an Agency in Suffolk County for a Record
An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
