Warren County Inmate Population Overview

The Warren County inmate population is housed primarily at the Warren County Correctional Center, the county adult correctional facility in Belvidere. Warren County describes the jail as the place used to detain adult offenders arrested for violations of laws and ordinances in the county. The facility is operated by the Warren County Corrections Department under the Warren County Board of County Commissioners, and the county identifies Warden Daniel Broesder as the direct commander. No separate state prison, Bureau of Prisons facility, ICE detention center, or sheriff annex was found inside Warren County in the official sources reviewed.

That single-facility map matters for search. A current local arrest normally points to the jail, while a state-prison sentence points to the New Jersey Department of Corrections. A federal case can move to the U.S. Marshals Service or the Bureau of Prisons, and immigration custody can move to ICE's locator. Hunterdon County adds one local wrinkle: its official Division of Corrections says Hunterdon contracted with Warren County in January 2020 to house all Hunterdon County inmates, so some people held in Warren may have Hunterdon booking or court records.

Warren County Inmate Population Statistics

Warren County publishes unusually useful jail population figures on its official corrections overview. The county says the building opened in 1986 with an original design capacity of 76 adult offenders. After internal renovations, the operating capacity is 176 adult offenders. The same county overview, inspected for this build in June 2026, reports an average daily population between 145 and 155 male and female adult offenders, plus about 20 adults in the County Labor Assistance Program and up to 6 adults and 6 juvenile offenders on electronic monitoring.

Warren County Inmate Population Trends

The best trend source in the research is the Vera Institute Warren County fact sheet, which gives a point-in-time comparison for May 2019 and May 2022. Vera reported 117 people incarcerated in Warren County on an average day in May 2019 and 100 people in May 2022, a 15 percent decrease. The current county overview reports a higher later average, between 145 and 155 adults, but the measures are not identical. The county figure may reflect later local changes, the Hunterdon housing arrangement, or a different reporting frame than Vera's snapshot.

Because those public sources use different time frames, the Warren County inmate population should not be reduced to one static number. The county page is the local primary source for current operating capacity and average daily population. Vera adds a historical comparison with pretrial, race, sex, admissions, and length-of-stay fields that Warren County does not publish as a full current dashboard.

Warren County Inmate Population Makeup

Warren County says its current jail average includes male and female adult offenders, but it does not publish a current public split by sex, age, race, offense level, or pretrial status on the county corrections pages reviewed. Vera's Warren County fact sheet fills part of that gap for historical snapshots. Vera reported that the pretrial share rose from 42 percent in May 2019 to 54 percent in May 2022. It also reported the female share at 16 percent in May 2019 and 17 percent in May 2022, and the Black share at 13 percent and 15 percent in those same snapshots.

• Pretrial status: Vera reported 42 percent pretrial in May 2019 and 54 percent pretrial in May 2022.
• Sex: Warren County says male and female adults are held; Vera reported a 17 percent female share in May 2022.
• Security level: The county uses minimum, medium, and maximum security housing areas after entry classification.
• Other counties: Hunterdon County inmates may be housed at Warren under the 2020 intercounty arrangement.
• Federal or ICE count: No current local count was published in the official sources reviewed.

Warren County Jail Capacity

Current county figures do not support a claim that the Warren County Correctional Center is over operating capacity. Using the county's 176 operating capacity and its 145-155 average daily population, the jail runs at about 82 to 88 percent of operating capacity before separately considering CLAP and electronic-monitoring participants. The old 76-bed design capacity is important history, but it should not be used as the current overcrowding denominator because Warren County says renovations raised the operating capacity to 176.

The facility's population is shaped by more than bed count. Warren County reports a podular design with remote and direct supervision, entry classification, and minimum, medium, and maximum housing areas. The County Labor Assistance Program gives some eligible straight-time or weekend-sentence defendants a way to serve days through community labor. Electronic monitoring is another alternative. Those programs keep some people under corrections supervision without treating every case as a full-time jail bed.

Warren County Inmate Population Laws

New Jersey law separates live custody questions from public-record requests. For live Warren County jail custody, the practical source is the Correctional Center phone line. For copies of records, New Jersey's Open Public Records Act, called OPRA, controls access to many government records subject to exemptions. Jail standards also matter because Warren County says the Correctional Center undergoes annual New Jersey Department of Corrections inspection and has achieved 100 percent compliance during those inspections.

Warren County State Prison Search

No NJDOC prison facility was found physically inside Warren County, so the local inmate population page should not add a state-prison facility card for the county. A Warren County defendant who receives a state prison sentence eventually leaves county jail custody and becomes searchable through the New Jersey Department of Corrections offender search. NJDOC says its locator is updated biweekly, may omit certain offenders, may not reflect fast changes, and removes most offenders one year after custodial term completion unless a CSL or PSL exception applies.

The NJDOC homepage is also the better starting point for state prison visitation, staying-connected tools, victim services, and state-level reentry links. Warren County jail rules for mail, money, phone calls, and visits do not transfer to a state prison. The local jail and NJDOC are separate systems, even when the same criminal case starts in Warren County.

Search Warren County Inmate Records

No official Warren County public current-inmate search portal, recent-bookings gallery, or web jail roster was located on the official county corrections or sheriff pages during the research sweep. A Warren County inmate lookup therefore starts with the fallback chain rather than an online name-search form. The most direct live channel is the Warren County Correctional Center phone line for current custody, bail verification, and housing-based visitation schedule questions.

1. Call the Warren County Correctional Center at 908-475-7900 for live county jail custody, bail, and visitation schedule checks.
2. If the arrest was in Hunterdon County, check Hunterdon County's current population and active charges page because Hunterdon inmates are transferred to Warren.
3. Use the Sheriff's OPRA process when the need is a booking sheet, jail record, report, or other identifiable record copy.
4. Search NJDOC when the person has been sentenced to state prison or transferred to state custody.
5. Use BOP for sentenced federal prisoners and ICE ODLS for immigration custody after transfer.
6. Search NJ Courts for formal criminal charges after the booking path moves into a court case.

Warren County Current Inmate Lookup

The absence of a Warren County web roster is itself a key records fact. The county publishes official pages for bail, visitation, mail, phone privileges, accounts, statistics, directions, and immigration enforcement, but not a public searchable current-inmate list in the sources reviewed. The table below should be read as a search-channel table, not as a claim that Warren County has online roster fields.

The Warren County Sheriff's OPRA page is especially important when no online roster exists. The sheriff explains that OPRA requests must identify records to inspect or copy. Copy fees listed by the sheriff are $0.05 per letter-size page and $0.07 per legal-size page, with actual cost for other materials and a possible deposit when copies exceed $25.

Warren County Inmate Record Fields

Because no official Warren County public roster profile was located, a Warren County page should not promise online fields such as booking photo, housing unit, booking time, or bond amount. Some fields may be confirmed by phone, appear in an OPRA response, show in court records, or appear in Hunterdon's active-charge PDF for Hunterdon inmates housed in Warren. The researched field inventory is narrower than a standard commercial roster profile.

The Hunterdon County current population and active charges page is relevant because Hunterdon states its inmates are processed in Hunterdon and transferred to Warren County Jail. The captured Hunterdon page is an official roster-style path for transferred Hunterdon inmates, not an official Warren County public roster.

Hunterdon County's active-charge page was captured in the image below as a local transfer-related source.

The screenshot helps explain why a Hunterdon arrest may require both Hunterdon and Warren records checks.

Warren County Jail vs State Prison

Custody type decides which locator to use. Warren County jail custody covers local pretrial detention, certain short sentences, programs such as CLAP, and transferred Hunterdon inmates. NJDOC custody covers sentenced state prisoners. Federal and immigration custody move outside the county lookup path. Mixing those systems leads to false negatives because the person may be in custody but no longer in the first database checked.

Warren County Booking and Bail

Warren County does not publish a public booking manual, but its official pages document the parts that matter for family searches. The jail classifies people upon entry to determine supervision level. During intake, inmates are allowed unlimited telephone calls for 72 hours or until they move to general population, as long as they cooperate with correctional and medical staff. After processing, the inmate receives a PIN for continued phone use and completes a telephone authorization form listing family, friends, bail agencies, and private attorneys.

The county's bail-posting page tells anyone interested in posting bail to call 908-475-7900 to verify the inmate's bail amount. During normal business hours, bail may be posted at the court or municipality where charges originated, then the receipt is taken to the jail for verification. On a 24-hour basis at the jail, posting is by money order. The county says cash is not accepted at the Correctional Center. Superior Court criminal charges carry a separate $50 non-refundable filing fee.

State and Federal Inmate Search

NJDOC, BOP, USMS, ICE, and VINE each answer a different search question. NJDOC covers selected information for state-sentenced offenders. BOP covers federal inmates from 1982 forward, generally after sentencing or BOP designation. USMS handles custody and transport from federal arrest until acquittal or incarceration in many cases. ICE ODLS searches adults in ICE custody or CBP custody over 48 hours. New Jersey VINE is a notification service for custody changes, not a full substitute for jail records.

NJDOC offender search was captured as a statewide locator used after a Warren County case moves into state-prison custody.

The state locator is useful only after the county-jail stage no longer controls the person's custody status.

Warren County Detention Facilities

The Warren County facility map has one local detention facility page. Municipal police custody should be treated as short-term arrest processing before transfer, not as a separate jail page. State, federal, and ICE custody are important search routes, but no separate facility of those types was found inside Warren County in the official sources reviewed.

• Warren County Correctional Center - county adult correctional facility for Warren County arrests, male and female adults, eligible program participants, and Hunterdon inmates transferred under the intercounty housing arrangement.

Warren County Jail Programs

Warren County's local program details help explain why the inmate population is not only a bed count. CLAP, the County Labor Assistance Program, gives eligible defendants sentenced to straight time a way to serve required days on weekends while remaining in the community during the rest of the week. Participants perform visible labor in the community and are monitored by corrections officials. The Electronic Monitoring Program is available to adult and juvenile offenders as an alternative to traditional detention.

The county also publishes conditions and oversight details. Warren County says the Correctional Center is inspected annually by NJDOC for state correctional standards and has achieved 100 percent compliance. It reports National Commission on Correctional Health Care accreditation. The county statistics page lists quarterly isolated-confinement reports from 2020 through January-March 2026, and the internal affairs page provides complaint channels and annual materials.
