Middlesex County Inmate Population is a private reference site, not a government office. It cannot confirm custody, release anyone, post bond, pull official booking records, or change a court or jail record. Use the official offices below for those tasks.
Official Routing for Jail and Records Questions
Use the contact that matches the type of custody or record. A person held locally after a Middlesex County arrest is different from a sentenced state prisoner, a federal inmate, or an immigration detainee.
Middlesex Jail & House of Correction
269 Treble Cove Road
Billerica, MA 01862
Phone: 978-667-1711
Use this facility contact for local jail custody routing, visit questions, and jail-office direction.
Middlesex Sheriff's Office
Administrative Office
12 Gill Street, Suite 4700
Woburn, MA 01801
Phone: 781-960-2800
The Sheriff's Office operates the Middlesex Jail & House of Correction and handles office-level jail administration.
MSO Records Access Officer
Megan McLatchey, Legal Division
12 Gill Street, Suite 4700
Woburn, MA 01801
Phone: 781-960-2830
Public records requests under M.G.L. c. 66, § 10 should reasonably describe the records sought and state the preferred electronic format when electronic records are requested.
Middlesex District Attorney
15 Commonwealth Avenue
Woburn, MA 01801
Phone: 781-897-8300
Use the District Attorney's Office for prosecution information that belongs to a pending or completed criminal case, not for jail custody confirmation.
For common lookup paths:
- For someone in the county jail, start with jail inmate records and the Billerica jail contact above.
- For booking photos, review jail roster mugshots and use the MSO public records route if a photo is not posted publicly.
- For charges filed after booking, use court records after a jail arrest, MassCourts, and the proper clerk or prosecutor channel.
- For a specific facility, use the facility pages listed in the footer for the jail, state prisons, and FMC Devens.
- For a sentenced Massachusetts state prisoner, use the Massachusetts Department of Correction and VINELink pathway.
- For federal custody, use the Federal Bureau of Prisons inmate locator. For immigration custody, use ICE ODLS.
