Benton County Jail Overview
Benton County MO Sheriff Detention Center is operated by the Benton County Sheriff's Office. The official detention page and county government sheriff page place the facility and sheriff/jail contact block at 1620 E. Main St., Warsaw, MO 65355. The jail is a county detention center, not a state prison. It is the local custody point for people arrested in Benton County, people held before trial, sentenced county inmates, municipal commitments when accepted, and holds for other agencies when those holds appear on the roster.
The official sources do not publish pod names, cell blocks, classification levels, medical unit counts, booking lobby rules, or housing assignment policies. The reliable local facts are narrower: the sheriff operates the jail, the roster identifies the population as people at Benton County MO Sheriff Detention Center, and the same official site provides current inmate and 48-hour release views. For sentenced felony custody after transfer, the correct source becomes the Missouri Department of Corrections, not this county jail page.
The official Benton County detention facility page gives the jail address, mailing address, and detention phone number.
That source is the best facility-level reference for basic contact and mail routing before calling or visiting.
Benton County Jail Population
Benton County planning documents describe the sheriff's office and jail project as an 80-bed facility, expandable to 100 beds. The county conceptual design referenced a $10 million project budget and a jail intended to meet county needs for more than 20 years. The 2018 construction-management RFP placed the project at 1620 E. Main St. and used an 80-bed jail with expansion capability as the planning basis.
The current roster showed 38 current inmates when inspected on June 19, 2026. That is a live roster snapshot, not an average daily population. The 48-hour release view showed 3 release entries on the same inspection date. No official Benton County annual booking count, average daily population report, average length of stay, or aggregate demographic report was located in the official materials reviewed.

Lookup Benton County Jail Inmates

It has separate paths for current inmates and people released within 48 hours. Roster cards can show a mugshot thumbnail, name, booking number, age, booking date, charge text, bond, and a profile link. Full profiles add fields such as gender, race, arresting agency, and a bond/charge disclaimer.

Benton County Jail Contact
The facility contact block should be used for custody questions, roster confirmation, mail questions, and detention-specific routing. The sheriff website footer gives the 24-hour non-emergency number as 660-438-5252 and administrative office hours as Monday through Friday, 8 a.m. to 5 p.m. The county government sheriff page names Eric Knox as sheriff and lists the sheriff/jail phone and fax.

Benton County Jail Visitation
The official sheriff FAQ publishes broad visitation windows for Benton County MO Sheriff Detention Center. It also says probation or parole visitors need written permission from their probation or parole officer, and juveniles must be with a parent or legal guardian. The FAQ does not publish locker rules, bag rules, dress code details, visitor ID wording, video-visit vendor information, or holiday lockdown rules.
Call the detention facility before travel if the visit depends on a work schedule, long drive, court date, medical lockdown, or new booking. Roster status and visit eligibility can change quickly after booking or court action.

Benton County Jail Mail
Mail for detainees goes to Benton County Detention Facility at the East Main Street address. The official FAQ says the detainee's name should be on the front of the envelope under the mailing address. Nonlegal mail is opened and checked for contraband before delivery. Legal mail is opened in front of the detainee. The FAQ also states that up to 6 photos may be mailed and that Polaroids are not allowed.
Money deposits and commissary orders use JailATM.com according to the official FAQ. Benton County did not publish a local JailATM fee schedule, phone pricing table, tablet vendor, video-visit vendor, or scanned-mail vendor in the official materials reviewed. Check JailATM during the transaction and confirm unusual mail or money questions with detention staff.

Benton County Jail Booking
Benton County does not publish a local booking manual, so the intake path should be read from the roster fields and Missouri jail law. A person arrested by the sheriff, Warsaw police, another Benton County agency, or an outside agency on a Benton County warrant may be transported to Benton County MO Sheriff Detention Center. Under Missouri law, the sheriff or jailer receives prisoners committed by lawful authority. Once accepted, the jail creates a booking record.
The public roster proves several intake elements: booking number assignment, age entry, booking date and time, arresting agency, charges, bond, and booking photo when shown. Charges and bond values may change after court appearances, and the profile disclaimer tells bond companies and people wishing to post bail to contact detention staff for correct bail, charges, and case numbers. Do not assume a person will appear online within a fixed number of hours because Benton County does not publish a roster refresh rule.
Custody flow: Arrest or warrant service > transport to county detention > jail acceptance and booking > roster listing > court review > release, county sentence, hold, or transfer.
Benton County Jail Bond
Bond information on the Benton County roster is useful but not final. Missouri law allows release on recognizance or with conditions set by a judge, including cash, surety, percentage deposit, supervision, travel limits, reporting, or electronic monitoring. An outside hold or detainer can also affect release. The official Benton County sources did not publish accepted bond payment methods, payment hours, cashier location, refund rules, a bondsman list, or an online bond portal.
The safest practical sequence is simple: read the roster bond field, open the profile, call detention staff at 660-438-6135, and check court information through Benton County Circuit Court or Missouri Case.net. The sheriff FAQ says court-date questions should go to Benton County Circuit Court at 660-438-7712 or Missouri Case.net. Roster charges are booking charges. Court charges may be filed, amended, reduced, dismissed, or replaced by the prosecutor and court.
Benton County Jail Records
The sheriff roster disclaimer says online records are provided as a public convenience and do not constitute official records of the Benton County Sheriff's Office or detention center. That matters for anyone checking a custody status, posting bond, reporting to court, arranging a visit, or trying to identify a court case. The online roster may lag behind court or detention updates.
For official confirmation, use direct detention contact, the sheriff's office address, and Missouri public-record procedures. No dedicated Benton County sheriff records-request PDF or fee schedule was located on the sheriff website. A written request should identify the person, approximate booking or arrest date, and requested record, such as a booking sheet, arrest record, or booking photo. Filed charges and hearings should be checked through Missouri Case.net or the Benton County Circuit Court.
About Benton County Jail
The current detention center sits in a public planning history. Benton County preserved new-jail information, conceptual design materials, public informational meeting dates in March 2018, and jail committee minutes from 2017. The project documents described a sheriff's office and jail on a greenfield site, funded through a county sales tax passed in April 2018. Official sources do not publish a program directory for GED, vocational training, substance-abuse treatment, religious services, reentry services, grievance procedures, tablet programs, or medical request forms.
The official FAQ does confirm practical conditions such as JailATM deposits, commissary gift funding, mail screening, legal mail handling, and visitor eligibility limits. Missouri law also requires medical, dental, or medicine attention for sick county-jail prisoners when the jailer judges it necessary, and grand jury or committee inspection of county jail condition and prisoner treatment. Those are legal framework points, not a published Benton County program list.
The Benton County sheriff FAQ is the main official source for visitation, mail, JailATM, court-date direction, and visitor limits.
The FAQ fills in day-to-day facility rules that are not visible from the roster alone.
Note: Confirm custody, bond, and visitation with detention staff before traveling or paying money.
