Barnstable County Inmate Population
The local jail count in Barnstable County is reported through the Barnstable County Sheriff's Office and statewide sheriff reporting, not through a public live roster. The only detention facility identified in the county facility map is the Barnstable County Correctional Facility in Bourne. It is a county jail and house of correction run by the Barnstable County Sheriff's Office. It holds pretrial detainees, male and female incarcerated people, people serving county sentences of no more than 2.5 years, and some high-risk or disciplinary housing populations.
The Barnstable County inmate population rises or falls with arrests, arraignment and bail decisions, short county sentences, releases, transfers, and court orders. A person can be booked into county custody after a Cape Cod arrest, then move out of that count if released, transferred, sentenced to the Massachusetts Department of Correction, placed in federal custody, or held through another system. That is why custody lookup in Barnstable County has to separate jail custody from court case records and from sentenced prison custody.
Barnstable County Inmate Population Statistics
The strongest recent capacity figures come from Massachusetts Sheriffs' Association operational capacity reports linked by official state and sheriff reporting pages. The Barnstable County Correctional Facility is listed as one building with a design capacity of 588. The January through June 2025 operational capacity report lists an average population of 256. The July through December 2025 report lists an average population of 262. Those figures show Barnstable County operating well below design capacity during both halves of 2025.
| Measure | Figure | Source / Year |
|---|---|---|
| Average population | 256 | Massachusetts Sheriffs' Association operational capacity report, Jan.-June 2025 |
| Average population | 262 | Massachusetts Sheriffs' Association operational capacity report, July-Dec. 2025 |
| Rated / design capacity | 588 | MSA operational capacity reports and BCSO history page, 2025 |
| County detention facilities in map | 1 | Barnstable County facility map research |
The BCSO reporting and data page is the local doorway to many population and data references. The screenshot below comes from that official reporting page.
Those reporting links matter because Barnstable County does not replace aggregate jail reporting with a public inmate roster.
Barnstable County Jail Population Trends
Barnstable County's published trend picture is not a long row of annual booking counts. It is a mix of facility history, audit snapshots, and 2025 operating reports. The BCSO history page says the current Bourne facility opened in 2004, has 12 pods, and has had an average census around 270 since 2024. A State Auditor report recorded 165 people in custody on June 30, 2021, with 98 pretrial detainees and 67 sentenced inmates. The two 2025 MSA averages then show the population in the mid-250s to low-260s.
| Source Date | Population Figure | Notes |
|---|---|---|
| June 30, 2021 | 165 total | State Auditor snapshot: 98 pretrial and 67 sentenced. |
| Since 2024 | About 270 average census | BCSO history page local summary. |
| Jan.-June 2025 | 256 average population | MSA operational capacity report. |
| July-Dec. 2025 | 262 average population | MSA operational capacity report. |
Barnstable County Jail Population Makeup
The Barnstable County inmate population includes more than one custody stage. Pretrial detainees are people held before a case is resolved. Sentenced county inmates are serving a county house-of-correction sentence, which the Auditor report describes as no more than 2.5 years. The June 30, 2021 Auditor snapshot gives the clearest local split: 98 pretrial detainees and 67 sentenced inmates. It also reported 89 male and 9 female pretrial detainees, plus 62 male and 5 female sentenced inmates.
- Pretrial detainees: People held before case disposition, including those awaiting arraignment, bail review, hearing, plea, trial, or other court action.
- Sentenced county inmates: People serving shorter county sentences at the house of correction rather than a state prison term.
- Female and high-risk housing: The Auditor report identifies House 2 as including female inmates, high-risk inmates, and disciplinary-rule violators.
- Sentenced state prisoners: People sentenced to state prison are no longer searched through Barnstable County jail records.
Barnstable County Jail Capacity
Capacity is a key part of the Barnstable County inmate population because the Bourne facility was built after older Barnstable Village jail space became inadequate. BCSO says the 1935 jail and later addition could not keep up with incarceration rates, leading to the current facility that opened in 2004. The current building has 12 pods and a maximum or design capacity of 588. With 2025 average populations of 256 and 262, the official capacity reports do not show the jail near its design limit during those reporting periods.
Population context: Design capacity is not the same as daily custody status. A person still has to be confirmed through BCCF, the court, DOC, BOP, or ICE depending on the custody system.
Barnstable County Inmate Population Laws
Massachusetts law explains why some Barnstable County inmate population data is public while some personal booking detail may be limited. M.G.L. c. 66, section 10 sets the public-records request process and response framework. M.G.L. c. 4, section 7, clause 26 defines public records broadly, including photographs, unless an exemption applies. M.G.L. c. 126, section 40 requires sheriffs to record and report aggregate jail and house-of-correction data each quarter. That statute is why the Barnstable Chapter 126 report includes fields such as race, ethnicity, admission type, release type, sentence length, jail credit, and earned time.
Key statutes:
M.G.L. c. 127, section 1A authorizes minimum standards for county correctional facilities.
M.G.L. c. 127, section 1B covers inspection reports, violation notices, and enforcement for county correctional facilities.
M.G.L. c. 127, section 2 requires superintendents to keep records for people in custody.
Barnstable County State Prison Search
No Massachusetts Department of Correction prison was found inside Barnstable County. That does not mean Barnstable County defendants stay in the county jail after every conviction. If a sentence is a state-prison term, custody shifts from the Barnstable County Sheriff's Office to the Massachusetts Department of Correction. Mass.gov says the DOC manages 13 institutions statewide. The DOC inmate lookup route uses Mass.gov's inmate lookup instructions, VINELink, or the VINE phone line at 866-277-7477.
The January 1, 2026 DOC FAQ reported a total jurisdiction population of 6,240, including 5,843 criminally sentenced DOC jurisdiction inmates. A February 23, 2026 DOC weekly count reported 6,067 people in DOC facility custody and noted that Barnstable county facilities held 0 DOC incarcerated individuals at that count. Those state figures belong to the DOC population, not the Barnstable County jail population.
Search Barnstable County Inmates
No official Barnstable County online jail roster, inmate-search portal, booking report, recent-booking feed, or mugshot gallery was located on the Barnstable County Sheriff's Office site during research. That finding changes the lookup path. A current Barnstable County jail search starts with the facility phone line and records route, then branches to court, DOC, BOP, ICE, or VINE based on custody type.
- Decide whether the person is likely in county jail, state prison, federal custody, immigration custody, or only in a court case record.
- For current county jail custody, call Barnstable County Correctional Facility general inmate information at 508-563-4300.
- For a booking, custody, or incident record, send a public-records request to the BCSO Records Access Officer at 6000 Sheriff's Place, Bourne, MA 02532, or fax 508-563-4511.
- For charges, court dates, warrants, or dispositions, search MassCourts or contact the Barnstable, Orleans, Falmouth, or Superior Court clerk.
- For sentenced state prisoners, use Massachusetts DOC/VINELink; for sentenced federal inmates use BOP; for immigration detention use ICE ODLS.
Barnstable County Roster Search Fields
Because there is no located public roster form for Barnstable County jail custody, the useful search fields are the details a caller or requester should have ready. The BCSO site does not promise what will be released by phone. It is safer to treat the call as a custody-confirmation starting point and use a written request when a record copy is needed.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| No official public roster | n/a | n/a | No Barnstable County roster, inmate-search form, recent-booking feed, or mugshot gallery was located. |
| Full name | Phone inquiry detail | Not published | Useful when calling 508-563-4300. |
| Date of birth | Phone inquiry detail | Not published | Helps distinguish people with similar names. |
| Arrest town or date | Phone inquiry detail | Not published | Useful when the arresting agency or date is known. |
| Record description | Public-records request detail | Recommended | BCSO says requests should reasonably describe the specific records sought. |
Barnstable County Released Inmate Records
Released Barnstable County inmates are not listed through a located public archive. For older booking or custody records, the practical path is a BCSO public-records request. The request should identify the person, date or approximate date, arresting agency if known, and the record sought. For case outcome, the court route is often stronger than the jail route because charges, dispositions, defaults, and sealing are court records. Barnstable County government separately states it does not possess criminal histories, arrest records, divorce records, adoption records, or court matters because those records belong to other offices or the Commonwealth.
Barnstable County Inmate Record Fields
Official research gives two different field inventories. The Auditor report says BCSO's internal offender management system stores names, genders, ethnicities, dates of birth, Social Security numbers, state ID numbers, booking numbers, booking dates, release dates, and in-custody housing assignments. That is not the same as a public roster. Chapter 126 reports include aggregate statutory fields such as PCF number, OBTN, race, ethnicity, admission type, release type, earned time, sentence length, and jail credit.
| Field | What It Shows |
|---|---|
| Booking number | Stored internally by BCSO, but no public Barnstable booking-number search was found. |
| Booking date | Stored internally and reflected in Chapter 126 population reporting fields. |
| Release date | Stored internally and may appear in report fields when applicable. |
| Housing assignment | Stored internally; public release should not be assumed. |
| Social Security number | Stored internally per the Auditor report and not suitable for public release. |
| Bail and disposition | Chapter 126 requires fields, but the report notes they originate with the Trial Court. |
Barnstable County Jail vs State Prison
A Barnstable County jail lookup is not the same as a Massachusetts prison lookup. The county jail covers local pretrial custody and county sentences. The DOC locator covers sentenced state-prison custody. BOP covers sentenced federal prisoners from 1982 to present, and ICE ODLS covers current or recent immigration detention. Many failed searches happen because the wrong custody system is searched first.
| County Jail | State Prison | |
|---|---|---|
| Who is held | Pretrial detainees and county sentences up to 2.5 years | People sentenced to Massachusetts state prison |
| Run by | Barnstable County Sheriff's Office | Massachusetts Department of Correction |
| Where to look | BCCF phone line and BCSO public records | MA DOC/VINELink and VINE phone lookup |
| Barnstable coverage | Primary county facility in Bourne | No DOC prison inside Barnstable County found |
State Federal ICE Inmate Search
Use Massachusetts VINELink for DOC and participating VINE custody, but do not assume Barnstable jail custody appears there because Barnstable participation was not documented. Use the BOP inmate locator for sentenced federal inmates. Use the ICE Online Detainee Locator System when immigration detention is suspected. USA.gov says ICE ODLS searches can use an A-number or a name, country of birth, and birth date.
The Massachusetts VINE portal screenshot below shows the state notification route, not a confirmed Barnstable County jail roster.
That distinction helps keep county jail custody separate from statewide prison and notification records.
Barnstable County Detention Facilities
The Barnstable County detention facility map resolves to one local facility page. No separate state prison, BOP facility, ICE detention center, or public municipal jail page candidate was found inside Barnstable County. Local police custody may occur at the start of an arrest, but long-term public jail custody routes through the county correctional facility or another state, federal, or immigration system.
- Barnstable County Correctional Facility - county jail and house of correction for pretrial detainees and county sentences of no more than 2.5 years.
Barnstable County Custody Terms
Several Massachusetts records terms appear across Barnstable County jail, court, and DOC lookup routes. Plain meanings help avoid mixing up a booking record with a court case or a prison record.
- Pretrial detainee
- A person held before case disposition, not yet convicted in that case.
- House of correction
- A Massachusetts county facility for pretrial detainees and shorter county sentences.
- Detainer
- A hold or request from another agency that can affect release even if local bail is posted.
- CORI
- Massachusetts Criminal Offender Record Information, a separate state criminal-history access system.
