Find Middlesex County Inmates

Middlesex Jail and House of Correction Overview

The Middlesex Jail and House of Correction sits in Billerica, about 45 minutes north of downtown Boston. Sheriff Peter J. Koutoujian leads the office. The facility holds men who are awaiting trial and men serving county sentences of up to two and a half years. Women classified to the office's pre-release program are housed at a separate unit. The facility is accredited by both the American Correctional Association and the National Commission on Correctional Health Care, the two main accreditation bodies in corrections. ACA accreditation covers facility operations, staffing, and policy. NCCHC accreditation means health services meet a national standard.

The jail is not a Massachusetts Department of Correction prison. DOC holds people serving state sentences longer than two and a half years. The federal Bureau of Prisons holds people convicted under federal law. If you are not sure which system a person is in, that question should be answered before starting a search, because the right tool depends entirely on custody type. County, state, and federal inmates are tracked in separate databases and cannot be found through the same search.

The Sheriff Peter J. Koutoujian executive office page is the official starting point for information about the office's leadership and mission.

That page also links to press releases and news items that document recent initiatives, training programs, and policy updates.

The jail's official page was last updated April 20, 2026, which suggests active maintenance. Still, individual booking profiles are not displayed publicly. The Sheriff's site has detailed pages for bail, visiting, mail, canteen, property, and public-records requests, but no roster grid or custody search that accepts a name and returns a match.

Is There a Middlesex County Jail Roster?

Many counties publish an online jail roster where anyone can type in a name and see whether a person is in custody. Middlesex does not. Research of the Middlesex Sheriff's website found no official public name-based inmate locator, no booking grid, and no searchable custody list. The Sheriff's site has pages for programs, bail, visiting, mail, and public-records requests, but none of them function as a name-search custody tool.

The Sheriff's website does include a site-wide search tool. That search looks through page content on middlesexsheriff.org. It does not query a custody database. Entering a name returns any page on the site that contains those words, not a booking record. The table below shows what the Sheriff site search actually does.

The jail overview page is still worth visiting for current facility information, even though it does not show individual inmate records. The Middlesex Jail and House of Correction official page covers the facility's role, accreditation, and population types.

The jail page also links to program descriptions, bail posting information, and contact details used throughout the sections below.

How to Verify Middlesex County Inmate Custody

Because no online roster exists, custody confirmation follows a short decision tree. The first question is which system has the person. From there, the right verification route becomes clear. Each step below handles one piece of that path.

1. Confirm custody type. Decide whether the person is likely in Middlesex county jail (awaiting trial or serving a short county sentence), in a Massachusetts DOC state prison (serving a sentence over two and a half years), or in federal Bureau of Prisons custody (federal charges or federal sentence). The answer changes which tool you use.
2. For county custody, call the jail. Call the Middlesex Jail and House of Correction at 978-667-1711. During normal business hours, staff can confirm whether a named person is in custody. After 4:00 p.m. and on weekends, press extension 0 to reach the on-duty contact.
3. Check the court docket. Open MassCourts eAccess and search the person's name in the Superior Court or District Court department. A docket for an active case may show bail set, bail posted, a mittimus, a release order, or a warrant. Docket entries often tell you whether the person was released or is being held.
4. Submit a public-records request. If a phone call is not sufficient, file a written public-records request with the Middlesex Sheriff's Records Access Officer. The Sheriff's public-records page at middlesexsheriff.org/238/Public-Records explains the process and how to submit. Releasable booking and custody records can be obtained this way, though some information is exempt under Massachusetts law.
5. For state prisoners, use VINELink. Massachusetts Department of Correction inmates can be located through VINELink. Mass.gov notes that only DOC participates in Massachusetts VINE, so county jail detainees are not in that system. VINELink is at vinelink.com or by phone at (866) 277-7477.
6. For federal prisoners, use the BOP Inmate Locator. The Bureau of Prisons runs a free name-based search at bop.gov/inmateloc. It covers sentenced federal inmates. Pretrial federal detainees held in contract facilities may not appear the same way as sentenced BOP prisoners.

Note: A person may move between county, state, and federal custody during a single case. Bail, sentencing, probation surrender, and detainers can all trigger transfers.

What Middlesex Inmate Records May Show

When a public-records request produces a releasable booking record from the Middlesex Sheriff, or when a court docket shows custody entries, the information available typically follows a standard set of fields. The table below describes each field and what it represents. These fields come from the type of information a county facility normally generates at booking. No official public roster at Middlesex exposes these fields online, but they form the basis for what a records request or docket review may return.

Medical records, mental-health evaluations, security classifications, victim information, juvenile records, and investigative materials are expected to be redacted. A January 2025 security incident at the Sheriff's Office resulted in a HIPAA breach notification, confirming that inmate health information is treated as protected. Do not expect health details from a records request.

Bail Posting at the Middlesex Jail

When a court sets bail and the person in custody cannot post it from inside, a family member or other party can go to the jail to post it in person. The Middlesex Sheriff publishes specific rules for bail posting, and the process differs from many other counties in one key way: cash only, with no alternative payment methods accepted for in-person posting.

The Middlesex Sheriff bail posting rules page outlines the requirements that anyone posting bail must follow.

Reviewing that page before you go can prevent a wasted trip, especially if the amount is large or the timing is close to the cutoff.

The 7:00 p.m. cutoff is firm. Arriving late means the person stays until the next business day at the earliest. Call first to confirm the amount and confirm the person has not already been released through a court order or other means.

Middlesex Jail Contact and Address

All in-person visits for bail, visitation, and mail inquiries run through the Billerica facility. The Sheriff's Office does not maintain a downtown walk-in location for these functions. Plan for the drive time, and check the current schedule before going because hours for specific activities can change.

The Sheriff's executive office and general contact information are at the Sheriff's executive office page. For public-records requests, the separate public records page at the Sheriff's site has the correct submission process.

Booking Process at Middlesex County Jail

When a person is arrested in Middlesex County and taken to the jail, the booking process follows a general intake sequence. The Middlesex Sheriff's public site does not publish a step-by-step booking flowchart, but standard county jail intake in Massachusetts moves through a predictable set of stages. Understanding those stages helps explain why custody information is not instantly visible online even when a person has been arrested.

After arrival, the person is received and identified. Staff search the person and their belongings under facility policy. A medical screening takes place. Fingerprints and photographs are recorded. The person is assessed for housing classification. If the case is new, a bail decision may come from a bail commissioner at the facility or from a court clerk-magistrate who can set bail after hours. If bail is not posted, the person stays held until a judge reviews the case at the next court session. Arraignment in District or Superior Court follows, typically the next court day.

For Middlesex County arrest records, the court docket often reflects booking events faster than any roster would, because the clerk's system records the arraignment, bail, and next court date as they happen. The docket does not tell you where physically in the facility the person is housed, but it does confirm custody and the case status.

Visitation at the Middlesex Jail

Visiting an inmate at the Middlesex Jail and House of Correction requires following the current rules on scheduling, identification, and prohibited items. The official visitor information and forms page is updated periodically, and the visiting schedule is maintained separately. Both should be checked before any visit because hours, procedures, and requirements can change.

Full visitor requirements and forms are at the Visitor Information and Forms page on the Sheriff's site.

That page was updated February 3, 2026, and contains the official visitor application and current requirements.

The visiting schedule is on a separate page. The Middlesex Jail visiting schedule page shows current day-and-time assignments, which may vary by housing unit and inmate classification.

The visiting schedule page was also updated February 3, 2026. The field inventory below shows what the official process requires.

Attorney visits and attorney mail are handled separately from social visits and family mail. The Sheriff's site includes an Attorney Mail page with its own rules. Do not apply the standard visitor schedule or mail addressing process to legal mail. Attorneys should use the dedicated attorney-mail instructions for privileged communication with clients held at the Middlesex facility.

Middlesex Jail Mail Rules

Mail is one of the main ways family and friends stay in contact with people held at the Middlesex Jail. The rules matter because mail that does not follow addressing requirements can be rejected before it reaches the recipient. The Sheriff's site has a dedicated mail page and a separate addressing-instructions page, both of which should be checked before sending anything.

The Middlesex Sheriff mail rules page covers what types of mail are accepted, size and content restrictions, and what happens to non-compliant items.

The addressing instructions page at middlesexsheriff.org/206/Addressing-Mail explains the exact format required for the envelope, including inmate name and any facility-required identifiers.

Legal mail follows different rules. Attorney-client correspondence is treated as privileged and processed separately from general social mail. Attorneys should not use the standard addressing format and schedule for legal communications. The Sheriff's sitemap identifies a separate Attorney Mail page, and lawyers with clients at the facility should use that page's current instructions rather than this general mail section.

Money Deposits and Canteen at Middlesex Jail

People held at the Middlesex Jail can use personal funds to buy canteen items including food, clothing, and toiletries. There are two ways to put money in an account: in person at the jail lobby, or through Access Corrections online and by phone.

The Middlesex Canteen and Property page covers deposit rules, property handling, and what the facility allows.

That page is the official source for current deposit limits, accepted items, and property rules when someone enters or leaves custody.

The lobby kiosk is open from 6:00 a.m. to 10:00 p.m. for deposits. For online or phone deposits, use Access Corrections at accesscorrections.com or call Access Corrections at (866) 345-1884. The Sheriff's site says MasterCard and Visa are accepted for electronic deposits through that service.

Property handling is a separate matter from canteen funds. The Canteen and Property page covers what the facility accepts at intake, what happens to items during a person's stay, and what the process is at release. Family members should check current property rules before trying to drop off or retrieve items, because what is allowed can change and the policy governs what the facility will accept at the door.

Jail Programs at the Middlesex Facility

The Middlesex Jail and House of Correction runs programming across several areas. These programs affect both the daily life of people in custody and the options available at release. They are worth knowing for family members trying to understand what is happening inside, and for anyone thinking about reentry planning. The Sheriff's site describes active units and programs rather than a single generic "rehabilitation" note.

Programs documented on the Sheriff's site include education and vocational training, addiction treatment, anger management, veteran housing (Housing Unit for Military Veterans), PACT, Project EARTH, the Older Adult Re-Entry Unit, the Women's Pre-Release Center, Family Support Services, Health Services, Victim Services, and PREA (Prison Rape Elimination Act) compliance. These are not placeholder names. The Sheriff's site maintains separate pages for most of these programs, several of which were updated April 20, 2026.

The Restoration Center of Greater Lowell opened in March 2026 as a direct partnership with the Sheriff's work. Located at 10 Technology Drive in Lowell, the center is operated by Vinfen and Spectrum Health Systems. It offers low-barrier, trauma-informed services including peer support, sober beds, detox, outpatient counseling, and medication for addiction treatment. The Sheriff's Office framed it as a Middlesex County pilot aimed at diverting people in behavioral health crisis from emergency rooms and the criminal justice system. That kind of diversion can affect who enters the jail and who gets a treatment-track alternative instead.

For people reaching the end of a county sentence, the Women's Pre-Release Center and the Older Adult Re-Entry Unit indicate that the jail provides structured transition support. Reentry planning topics are covered in more detail on the Middlesex County released inmates page, which walks through what happens after someone leaves county custody.

Sheriff Public Records Requests

The Middlesex Sheriff's Office is a public agency subject to the Massachusetts Public Records Law. A person who cannot get custody information by phone, or who needs a document for legal or personal reasons, can file a written public-records request with the Sheriff's Records Access Officer. The request process follows the state framework, and the office is required to respond within the statutory time period.

The Middlesex Sheriff Public Records page explains how to submit a request, what to include, and what the process looks like from submission to response.

That page was last updated February 3, 2025, and is the correct starting point for any formal records request to the Sheriff's Office.

What the request can and cannot get is shaped by state law. Booking records and custody information are generally public. Medical records, mental-health records, security classifications, victim information, ongoing investigative materials, and some personnel records are exempt. A January 2025 security incident at the Sheriff's Office produced a HIPAA breach notification covering protected health information of people the office had provided medical care to. That confirms health details are treated as protected and will not appear in a typical public-records response.

If you need a court document rather than a Sheriff document, the correct place to request it is the clerk's office for the court that handled the case. The Sheriff does not hold court files. For court records in Middlesex, start with the Clerk of Court for the relevant Trial Court department. For the underlying criminal case file, the Middlesex County court records page covers that process.

DOC, VINELink, and Federal Inmate Searches

Not everyone held in Middlesex County is in county custody. State and federal prisoners can be physically housed in or near Middlesex but belong to different tracking systems entirely. Knowing which system applies is the difference between finding someone quickly and searching the wrong database for days.

For people sentenced to Massachusetts state prison, the Massachusetts Department of Correction is the right place. DOC holds people serving sentences longer than two and a half years. The DOC inmate locator is at the DOC's main site and works as a name-based search for current and recently released state prisoners. VINELink, at vinelink.com or (866) 277-7477, also covers Massachusetts DOC inmates and can set up release notifications for victims and other registered parties. Mass.gov is clear that only DOC participates in Massachusetts VINE. County jail detainees at Middlesex are not in the VINELink system.

For federal cases, the Bureau of Prisons Inmate Locator at bop.gov/inmateloc searches by name or BOP register number. It covers sentenced federal prisoners in BOP facilities. People held pretrial in federal cases may be at contract facilities and may not appear through BOP the same way a sentenced federal prisoner does. The U.S. Marshals Service holds pretrial federal detainees, and their locations are not published in a public database. For federal cases with a Middlesex connection, the U.S. District Court for the District of Massachusetts handles the docket, and case information is searchable through PACER.

For people released from any system, the Middlesex County released inmates page covers VINELink notification setup, court docket release clues, BOP release date searches, and reentry resources in more detail. For current jail population data rather than individual custody, see Middlesex County inmate population.

Warrants, Arrest Records, and Related Searches

Inmate custody and warrants are closely linked. Someone held at the Middlesex Jail may have an active warrant from another case or jurisdiction. And someone with an outstanding warrant who has not yet been arrested is not in any inmate database because they have not been booked. The Middlesex Sheriff's Warrant Apprehension Unit is active. In 2025, the unit participated in arrests of more than 500 people wanted on Massachusetts charges and cleared 935 warrants, according to a February 2026 Sheriff's press release. The unit works with Lowell Police, Massachusetts State Police VFAS, and the U.S. Marshals Fugitive Task Force.

For active warrant questions, see Middlesex County warrant records. For the underlying criminal case file and arrest history, see Middlesex County arrest records. For recently released individuals and notification options, see released inmates. For county population data, see jail population.
