Middlesex County, Massachusetts Inmate Search

The Middlesex County inmate lookup portal lets you search current jail roster records by name. The Middlesex Sheriff’s Office operates the county jail — the Middlesex County House of Correction in Billerica — and maintains custody records for all persons held there. If the online search returns no result, call the jail directly at (833) 963-2494. Massachusetts’s CORI law (M.G.L. c. 6, §§167-178B) restricts some booking record details from public view.

Searching the Middlesex County jail roster

“Public records in Massachusetts are governed by M.G.L. c. 6, §§167-178B” — the CORI statute — which means the Middlesex County online roster shows only what the law permits. The inmate lookup portal at middlesexcountycourt.us/inmate-search is the starting point for a name-based search. Booking date, charges, and facility location are typically displayed for current detainees held at the Middlesex County House of Correction in Billerica.

1. Go to middlesexcountycourt.us/inmate-search.
2. Enter the person’s last name in the search field. A first name narrows results.
3. Review the returned records for booking date, charges listed, and current housing unit.
4. If no record appears, call the Middlesex Sheriff’s Office at (833) 963-2494 to confirm custody status directly.

The Middlesex Sheriff’s Office public records page handles formal records requests for documents not available through the online portal. For case docket information after arraignment, use the Massachusetts Trial Court docket search.

What the roster does (and doesn’t) show

Juvenile records, sealed cases, and persons held in federal custody do not appear on the Middlesex County jail roster. Massachusetts’s CORI statute (M.G.L. c. 6, §§167-178B) is among the most privacy-protective in the country. Booking photos are not publicly released for county jail detainees under this framework. Persons transferred to a Massachusetts Department of Correction state prison also drop off the county roster once the transfer is complete.

The roster reflects current county jail detainees only. It does not show persons who have been released, transferred, or are awaiting transport. Charges shown are as booked — they may not reflect subsequent court modifications. The roster updates on a rolling basis, so a booking from earlier in the day may not yet appear when you search.

If someone was just booked tonight

The Middlesex County House of Correction in Billerica is where most county arrests land. Call the jail at (833) 963-2494) to confirm custody — that’s the fastest path right now. The line is staffed around the clock for custody questions, so the hour doesn’t matter. That part is the hard part — waiting for confirmation at 11 PM with no information.

Bond is set at first appearance, which typically happens within 24 to 72 hours of booking in Massachusetts. Calling tonight confirms whether your person is in custody and which facility they’re at — it won’t get you a bond amount yet. One practical note: bail at the Middlesex Jail & House of Correction must be posted in cash only, and the bail posting window runs 6:30 PM to 7:00 PM daily. Plan around that window once bond is set. That’s a tight window — worth knowing now.

Visitation is not available tonight. The Middlesex Sheriff’s Office visiting schedule and visitor information and forms are where you’ll find hours once the booking settles. Attorneys can submit a request using the attorney visit request form. It’s a long night — but visitation typically opens the next day.

Tomorrow morning, call the Middlesex Superior Court clerk at (781) 939-2700 to ask about the first appearance date and time. If you need a lawyer, the Committee for Public Counsel Services handles public defender assignments in Massachusetts. You can also search for private attorneys through the Mass.gov lawyer finder. Getting legal counsel lined up before the first appearance matters.

If someone isn’t on the Middlesex County roster

Why might a name not appear on the Middlesex County roster right now? The most common reason is booking lag — a person arrested in the last several hours may not yet be entered into the public-facing system, even though they are physically in custody at the Middlesex County House of Correction in Billerica. Call (833) 963-2494) to confirm custody directly before drawing conclusions from a blank search result.
