Mahnomen County Jail Overview
Mahnomen County Jail is the primary local detention facility identified for Mahnomen County. It is operated by the Mahnomen County Sheriff's Office, led by Sheriff Josh Guenther, at 311 North Main Street, Mahnomen, MN 56557. The sheriff page confirms a Jail Administrator and Dispatcher/Jailers as part of the office structure, which supports treating the jail as a sheriff-operated local detention facility rather than a separate corrections department.
The official county sources reviewed do not publish a standalone jail page, online roster, booking-photo gallery, bed count, housing-unit description, exact security classification, commissary vendor, phone vendor, or visitor schedule for Mahnomen County Jail. That absence should be treated as useful operational information: call before visiting, mailing anything, trying to deposit money, or relying on an online search result. The sheriff's office is the confirmed local channel for current custody questions.
The sheriff serves Mahnomen, Bejou, Waubun, Naytahwaush, and 16 townships across 576 square miles. The same office handles law-enforcement, civil, courtroom-security, dispatch, jail, and transport functions, so jail information may come through sheriff or dispatch/jail staff rather than a dedicated public jail-records portal.
Mahnomen County Jail Capacity and Population
Official sources reviewed did not publish a Mahnomen County Jail bed capacity, current population count, average daily population, annual booking total, jail demographic table, or multi-year custody trend table. No third-party capacity number should be used as a substitute for an official figure. The published local figures are limited to the sheriff's 576-square-mile service area and the sheriff staffing list that includes jail staff.
| Measure | Official Mahnomen Status | Use in Lookup |
|---|---|---|
| Rated capacity | Not published in official sources reviewed | Do not assume bed count from directories or neighboring facilities. |
| Current jail population | Not published in official sources reviewed | Call 218-935-2255 for current custody questions. |
| Average daily population | Not published in official sources reviewed | No local ADP trend should be stated without an official source. |
| Annual bookings | Not published in official sources reviewed | Use sheriff data request channels if a public aggregate is needed. |
| Sheriff service area | 576 square miles | Shows the rural county service geography covered by the sheriff. |
No fake stat block: Mahnomen County did not publish the capacity and population figures needed for a numeric stat panel. The accurate facility-page treatment is a not-published table and a call-first custody route.
How to Look Up an Inmate at Mahnomen County Jail
Mahnomen County did not publish an official online jail roster in the sources reviewed. To confirm current local custody, start with the sheriff's office. Then use court, state, federal, and immigration systems based on what happened after arrest. A person may be locally booked, released before charges are filed, transferred to another agency, held on a court order, sentenced to MNDOC, or moved into federal or immigration custody.
- Call Mahnomen County Sheriff's Office at 218-935-2255 and ask whether the person is currently held, recently released, transferred, or known to be under another agency's custody.
- Have the person's full name, date of birth if known, approximate arrest date, and any case number ready before calling.
- For filed Mahnomen County criminal cases, search Minnesota Court Records Online and use the Mahnomen County filter or known case number.
- For state-sentenced custody, use the MNDOC Locator, which covers adults committed to the Commissioner of Corrections and still under DOC jurisdiction.
- For federal sentenced custody, use the BOP Inmate Locator. For immigration detention, use ICE ODLS. For U.S. Marshals custody, use USMS FOIA or District of Minnesota contacts.
The county contact page says the general website form is not for public safety, emergency, or legal matters. Emergencies go to 911, sheriff questions go to the sheriff phone line, and court schedule or order questions go to Court Administration.
Mahnomen County Jail Address and Contact
The official sheriff page is the best local contact card for jail questions because no separate jail lobby page was located. The county also maintains a general contact page, but the research notes that sheriff matters should be directed to the sheriff phone number rather than the general web form.

The facility is in the county seat near the courthouse and county offices. U.S. Highway 59 and Minnesota State Highway 200 are the main regional approaches to Mahnomen. The Minnesota Judicial Branch page for Mahnomen District Court says free surface-lot and on-street parking are available at the courthouse, but it does not create a jail visitor parking rule. Call before driving.
The official Mahnomen County Sheriff page provides the source contact block and staffing details for Mahnomen County Jail.
Use the sheriff page for the confirmed address, phone, fax, sheriff name, and staffing context, then confirm the current jail procedure by phone.
Visiting Someone at Mahnomen County Jail
No official Mahnomen County Jail visitation schedule, video-visitation rule, visitor approval form, dress code, lobby hours, or holiday policy was located in the county sources reviewed. Do not assume visiting days or hours from another Minnesota jail. Call 218-935-2255 before traveling, and ask whether visits are available, whether they are in person or video, what identification is required, and whether the inmate must place the visitor on an approved list.
| Topic | Published Mahnomen Detail | Call-First Action |
|---|---|---|
| In-person visits | Not published | Ask whether visits are allowed that day and how to schedule. |
| Video visits | Not published | Ask whether Mahnomen uses video visiting or another method. |
| Visitor ID | Not published | Bring government photo ID unless jail staff gives different instructions. |
| Visitor approval | Not published | Ask whether the person in custody must approve visitors first. |
| Attorney visits | Not published | Attorneys should coordinate directly with jail or court staff. |
Mail, Phone, and Money at Mahnomen County Jail
The official Mahnomen County sources reviewed did not publish an inmate mail format, commissary vendor, deposit vendor, fee table, inmate phone vendor, tablet service, property-release rule, or approved-item list. The safest instruction is to call before sending money, mailing property, attempting a deposit, or expecting a phone or video account to work.
| Service | Official Detail Found | What to Ask |
|---|---|---|
| Mail address | No inmate-mail format published | Confirm the correct name line, booking identifier if any, mailing address, and prohibited items. |
| Phone or video | No vendor published | Ask whether calls, voicemail, video, or messaging are available and whether accounts are needed. |
| Commissary or money deposit | No vendor or fee schedule published | Ask whether deposits are accepted and what forms of payment are allowed. |
| Property drop-off | No hours or accepted-property list published | Confirm approved items, drop-off times, and whether staff approval is required. |
| Release property | No local rule published | Ask how the inmate authorizes release and what ID the pickup person must bring. |
Regional facilities in Minnesota sometimes publish detailed video-visitation and commissary systems, but those vendor details were not found for Mahnomen County Jail. Do not import another facility's Securus, Turnkey, Inmate Canteen, or kiosk rules unless Mahnomen staff confirms them.
Who Is Held at Mahnomen County Jail
Mahnomen County Jail should be described as a local detention facility. The researched population categories include locally arrested adults, pretrial detainees, sentenced misdemeanants or other local inmates, court holds, warrant holds, and persons awaiting transfer when accepted by the Sheriff's Office. The record path depends on the legal authority behind the custody.
| Custody Type | Where to Check |
|---|---|
| Current local custody | Call Mahnomen County Sheriff's Office at 218-935-2255. |
| Filed county criminal case | Search MCRO or contact Mahnomen County District Court. |
| State prison sentence | Use MNDOC Locator after the person is committed to DOC jurisdiction. |
| Federal sentence | Use BOP Inmate Locator. |
| Immigration detention | Use ICE ODLS, not a county jail roster. |
| U.S. Marshals custody | Use USMS FOIA or District of Minnesota contact channels. |
Juvenile, tribal, federal, and immigration matters may use separate systems. Because the county court page links White Earth Reservation Tribal Court as a related resource, it is not accurate to assume every local legal matter appears only in Mahnomen County District Court.
Booking and Intake at Mahnomen County Jail
Official Mahnomen sources do not publish a step-by-step jail intake procedure, so any booking description should remain general. A Mahnomen arrest may start with a law-enforcement stop, warrant arrest, court remand, probation or supervised-release hold, or transfer request from another agency. If the person is accepted for local custody, jail intake commonly includes identity confirmation, search and property inventory, fingerprints, a booking photograph, warrant or hold checks, screening, and initial housing or transfer decisions.
The first court stage is separate from the booking desk. Minnesota Statutes section 629.725 governs taking an arrested person before a judge, and filed cases are handled through Mahnomen County District Court in the Ninth Judicial District. Court Administration, not jail staff, is the better channel for court schedules or court orders once a case is filed.
Court and Bond Contacts
The sheriff confirms local custody, but bond and court schedule details may be controlled by the court once a case exists. Mahnomen County District Court is located at the courthouse address on North Main Street, and the Minnesota Judicial Branch page lists regular court hours, parking information, and the court phone line. The county Court Administration page and county contact page direct court schedule or court-order questions to 218-935-2251.
Minnesota bail law treats money bail as court-administered once accepted by a judge and deposited with the court administrator. If a person is held on a no-bond hold, warrant, probation violation, federal detainer, immigration hold, or transfer order, paying money may not result in release. Confirm the custody hold with the sheriff and the court order with Court Administration before making plans.
State, Federal, and ICE Transfers
No state prison, federal BOP prison, ICE detention center, or U.S. Marshals detention facility was located in Mahnomen County. The Minnesota DOC adult facilities list confirms the state-prison search path is statewide rather than a Mahnomen facility page. A person sentenced to state prison may first appear in local jail or court records, then move into MNDOC custody after sentencing.
Federal and immigration systems should be searched directly. BOP covers federal inmates incarcerated from 1982 to present. ICE ODLS locates current immigration detainees using A-number and country of birth or biographical details. U.S. Marshals prisoner records are handled through FOIA rather than a public local jail roster.
About Mahnomen County Jail
Mahnomen County Jail operates within a small rural sheriff's office rather than through a large public corrections portal. The official sources reviewed confirm the sheriff operator, address, phone, fax, service geography, jail staffing, and local court context, but they do not publish the operational details that many larger jails place online. That makes direct confirmation important for custody, visiting, mail, deposits, and property questions.
Minnesota public-records and jail standards still matter even when the local website is sparse. Minnesota Statutes sections 13.03, 13.82, 13.85, and 641.05 frame access to government, law-enforcement, corrections, and jail-register data. Minnesota Rules Chapter 2911 supplies statewide jail standards, and Minnesota Statutes section 241.021 gives MNDOC inspection and facility oversight authority.
Note: Confirm custody, visiting, mail, money, and property rules with Mahnomen County Sheriff's Office before traveling or sending anything.
