Middlesex Jail Inmate Overview
The Middlesex Sheriff's Office jail page identifies Middlesex Jail & House of Correction as the Billerica facility for county jail and house of correction custody. It is not a state prison and it is not a federal medical center. The sheriff's office states that the facility holds men awaiting trial, men serving county sentences up to 2.5 years, and women classified to the office's pre-release center. That mix matters for any Middlesex County inmate lookup because a person can be in Billerica before trial, after a short local sentence, or while classification decides the next step.
The jail is operated by the Middlesex Sheriff's Office. The official jail page also states that the facility is accredited by the American Correctional Association and the National Commission on Correctional Health Care. Its public pages cover visitation, bail, canteen, property, mail, phone service, video, programming, transportation, victim services, and women's pre-release. A county jail record may therefore involve several offices inside the same facility, not just a booking desk. A person looking for current custody should separate the custody question from later needs such as bail posting, property pickup, or a public records request.
The official jail overview is shown in the screenshot from the Middlesex Jail & House of Correction source page.
The source page is useful because it puts the address, phone, bail routing, canteen information, accreditation, and jail leadership in one official location.
Middlesex Jail Population Records
The most specific current population figure in the research is the Massachusetts Sheriffs' Association May 2025 Average Daily Population report. It lists Middlesex custody ADP at 751.00, with 477.00 pretrial males, 259.00 sentenced males, 14.00 sentenced females, and 1.00 pre-arraignment male safekeep. The same research notes that the Prison Policy Initiative Census 2020 vintage correctional facility locator lists 900 prisoners for Middlesex Co. Jail & House of Corr. That 900 figure is a Census 2020 locator count, not a current rated capacity found on the sheriff's facility page.
| Measure | Figure | Source context |
|---|---|---|
| Total custody ADP | 751.00 | Massachusetts Sheriffs' Association, May 2025 |
| Pretrial male ADP | 477.00 | Massachusetts Sheriffs' Association, May 2025 |
| Sentenced male ADP | 259.00 | Massachusetts Sheriffs' Association, May 2025 |
| Sentenced female ADP | 14.00 | Massachusetts Sheriffs' Association, May 2025 |
| Census 2020 locator count | 900 prisoners | Prison Policy Initiative facility locator |
Middlesex Jail Inmate Lookup
No public Middlesex Sheriff's Office inmate roster was found in the research sweep. That means a Middlesex Jail & House of Correction inmate lookup should start with the jail phone line and, when a formal record is needed, the sheriff's public records process. A person sentenced to a Massachusetts Department of Correction prison is searched through MADOC and VINELink, not through a county jail list. Federal custody at FMC Devens is searched through the Bureau of Prisons. Keeping those systems separate prevents a false negative when a person has moved from county jail to state or federal custody.
- Call Middlesex Jail & House of Correction at 978-667-1711 with the person's full legal name, date of birth if known, arrest date, and arresting agency.
- For a formal jail record, use the MSO public records page and describe the booking, custody, or control-number record sought.
- If the person has a state prison sentence, use the MADOC inmate finding page and VINELink with a full first and last name or commitment number.
- If the person is in federal custody, search the BOP inmate locator by register number or name.
| Search path | Use when | What to have ready |
|---|---|---|
| Jail phone | Possible current Billerica custody | Full name, date of birth, arrest date |
| MSO records request | Booking, custody, or control-number record | Reasonable description and preferred format |
| MADOC/VINELink | Sentenced state prison custody | Full first and last name or commitment number |
| BOP locator | Federal inmate custody | Register number or name details |
Middlesex Jail Address and Contact
The public facility address and main phone number should be used for custody and visit routing. The public records address is different because formal record requests go through the Middlesex Sheriff's Office Legal Division in Woburn. Bail questions after regular office hours and on weekends go through the main jail number, with callers pressing 0 as the MSO jail FAQ directs.

Middlesex Jail Visiting Schedule
The official visitor information page says visits are 45 minutes. Processing starts 30 minutes before a visit session on a first-come, first-served basis and closes 15 minutes before the session begins. Each visit is limited to two adults and four children. Adults need valid government photo ID. A parent or guardian bringing a child under 18 must present the child's birth certificate. Visitors should expect screening and should check the unit schedule before travel because pods, dorms, HSU, OAR, CWP, and work release have different windows.
The visit schedule below is a compact version of the MSO visiting schedule. It is not a substitute for confirming the exact pod or unit on the day of the visit.
| Day | Published unit examples | Visitor action |
|---|---|---|
| Sunday | C-Pod, HSU/first tier, CWP/W-R, D-Pod, A-Pod | Confirm the assigned housing unit first |
| Monday | E-Pod, Dorms, first-tier areas, B-Pod, OAR | Arrive early for processing |
| Tuesday | HSU, F-Pod, Dorms, C-Pod | Bring photo ID and child documents |
| Wednesday | D-Pod, OAR, Dorm 2, CWP/W-R, F-Pod | Verify the session has not changed |
| Saturday | A-Pod, B-Pod, OAR, CWP/W-R, C-Pod | Use the official schedule for times |
Middlesex Jail Mail and Money
Bail at the jail has a narrow official window. MSO states that bail is posted at the Visiting Center between 6:30 p.m. and 7:00 p.m., no later than 7:00 p.m., Monday through Sunday. Bail is cash only, and the person posting bail must present valid government-issued photo ID. For canteen, the lobby kiosk is available from 6 a.m. to 10 p.m.; online deposits use Access Corrections; phone deposits use 866-345-1884. Package ordering is through the Middlesex Packages vendor path, with phone support at 800-546-6283.
Effective August 1, 2024, personal and nonprivileged mail is routed to Securus for digital scanning. The MSO mail page says originals are held by Securus for 60 days before destruction unless the sender includes a return envelope. Legal mail and approved publisher or retailer publications follow different rules. Phone, video, and e-messaging are also through Securus. There are no incoming personal calls, and MSO states that calls are recorded and monitored.

Middlesex Jail Records Verification
A Middlesex Jail & House of Correction booking record may include name, aliases, date of birth, booking or control number, arresting agency, booking date, charge text, court of jurisdiction, bail status, custody status, housing facility, and release or transfer date if those items are releasable. The research warns not to claim that a public jail profile shows mugshots or housing units because no official public MSO roster was found. Public records may be redacted for privacy, safety, investigatory, juvenile, or other Massachusetts exemptions.
Note: Confirm custody, bail, and visiting details with the jail before travel because records can change after court or classification action.
