Mason County Jail Roster Overview
The Mason County Sheriff's Department runs the county jail and holds its inmate records. Research found no official online roster, inmate-search portal, or recent-bookings feed on the county, court, or state sites. That means there is no live page to refresh and no county search form to fill in. The fastest confirmation of current custody is a phone call to the sheriff, and written records come through a public-records request.
The county roster, even by phone, only covers local custody. It does not show sentenced state prisoners, federal inmates, or immigration detainees. Those people are searched through separate systems. Knowing that split up front saves time, because a name missing from a jail phone check may simply have moved into one of the other systems after sentencing or transfer.
How to Use the Mason County Inmate Roster
Without an online roster, the lookup is a short chain of calls and requests. Start with the sheriff, then escalate to a written request if you need something on paper. Have the person's full name ready, and a birthdate or booking date if you can get one.
- Call the Mason County Sheriff's Department at 309-543-2231 and ask the jail or booking desk about current custody.
- Give the full legal name, plus a date of birth, arresting agency, or rough booking date.
- Ask whether the person is still held, released, transferred, or kept for another jurisdiction.
- For a written booking record, custody dates, or a photo, file a FOIA request with the sheriff's office.
The county also confirms there is no Mason County sheriff mobile app with an inmate or warrant lookup. Several app-store results point to Mason County in other states, so treat those as the wrong jurisdiction. The phone line and the records request remain the local channels.
Mason County Roster Search Fields
There is no county roster form to inspect, so no official Mason County search fields exist to list. The closest searchable system that applies to former county inmates is the statewide IDOC locator, which kicks in once a person is sentenced and moved to prison. Its search fields are shown below so the lookup path is clear.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Last Name | Text | One method required | Full last name or its beginning letters |
| IDOC Number | Text | One method required | Example format K01234 |
| Birthdate | Date | One method required | Example format 04-01-1965 |
The state locator is the front door for sentenced prisoners. The IDOC Individual in Custody Search opens the search by last name, number, or birthdate.

That state page does not help for someone still in the Mason County Jail, but it is the right tool the moment a person is sentenced and transferred out of the county.
What a Mason County Inmate Profile Shows
Since no public county profile is posted, the field list here describes the statewide IDOC profile, which is the closest public record. A Mason County booking file holds similar fields inside the jail's own system, but those reach the public only through a records request. The state inspection confirms the jail keeps booking and personal records, property receipts, medical notes, visitor logs, and release-authority records internally.
| Field | What It Shows |
|---|---|
| IDOC Number | The state ID for a sentenced prisoner |
| Name and Photo | Legal name and a state photo when available |
| Parent Institution | The prison currently holding the person |
| Offender Status | In custody, paroled, or discharged |
| Admission Date | When state custody began |
| Sentence and Offense | Charge, class, county, and projected dates |
A county booking record instead centers on a booking number, intake date, the charges at arrest, and the authority for release. One important Illinois detail shapes those records: the state no longer uses cash bail as the standard release tool, so a booking file will not list a fixed bond amount the way older records did.
Finding County, State, and Federal Inmates
Four systems split the work, and each covers a different kind of custody. The county handles pre-trial and short-sentence inmates. The state handles sentenced felons. The federal Bureau of Prisons handles sentenced federal inmates, and ICE handles immigration holds. Pick the system that matches the person's situation, then use its locator or contact.
| Custody | Where to Look |
|---|---|
| Pre-trial / short sentence | Mason County Sheriff, by phone or FOIA |
| Sentenced felon | Illinois Department of Corrections locator |
| Federal | Federal Bureau of Prisons locator |
| Immigration hold | ICE detainee locator |
The state list also confirms no prison sits in the county itself. The IDOC all-facilities page shows there is no Mason County or Havana state prison.

Because no prison is in the county, every sentenced Mason County resident is held somewhere else in Illinois and must be found through the state locator rather than the local jail.
VINELink, BOP, and ICE Fallbacks
Two more channels round out the search. For custody and case alerts, Illinois VINELink lets a victim or family member register for notifications when a status changes. It draws from county jail booking systems, IDOC, and the circuit courts, and it can reach you by phone, email, text, or app. It is a notification tool, not a full booking archive, so it works best alongside the sheriff phone line.
The alert system is open to the public statewide. Illinois VINELink handles custody status and registration for notices.

For sentenced federal prisoners, the federal locator is the right tool, and it has no Mason County facility of its own. The Bureau of Prisons inmate locator searches by number or by name.

The nearest federal prison is FCI Pekin in neighboring Tazewell County, not Mason. For immigration custody, the ICE detainee locator searches by alien number or by name and birthdate.
Mason County Jail Facility
The county holds its inmate population in one building. There is no annex, work-release center, or regional jail to search separately. The contact card below carries the address and phone, and the facility page goes deeper on housing, visitation, and conditions.

Booking Process in Mason County
Local arrests are brought to the jail at 102 West Market Street when detention is appropriate. The state inspection lays out the intake steps the jail must follow: officers confirm the legality of the confinement and the person's identity, conduct a search under privacy rules, take fingerprints and a photo, and inventory property on a signed receipt. Intake also includes medical and mental-health screening and a reasonable number of completed phone calls as soon as practicable.
After intake, the case moves to the court side. Illinois ended cash bail as the standard release mechanism, so release or detention is decided by the court under the Pretrial Fairness Act rather than a fixed bond schedule at the jail. The prosecutor may ask for detention in eligible cases, and the court may set nonmonetary conditions. The charges filed in court are covered on the court records after a jail arrest page.
Note: the county did not publish how many hours after booking a person appears in any list, because there is no public roster, so a phone call is the quickest custody check.
Requesting Mason County Booking Records
When you need something in writing, the route is a public-records request to the sheriff under the Illinois Freedom of Information Act. The sheriff is the named FOIA officer for the jail. Send the request to Sheriff Paul Gann, 102 W. Market Street, Havana, IL 62644, or email mcsheriff@masoncountyil.gov. Identify the person as fully as you can, and name the specific records you want, such as a booking record, custody dates, an arrest report, or a booking photo.
Illinois sets the ground rules for the response. A public body generally has five business days to answer, with limited extensions, and the county FOIA directory says the first 50 pages of an allowable non-commercial request come at no cost. Some material can be redacted or withheld under the law's law-enforcement, privacy, juvenile, and security exemptions, so a booking photo or an active-case record may come back partly blacked out or denied with a reason. Basic arrest-report facts, by contrast, are due within 72 hours under a separate provision.
Note: for a current custody question the phone line is faster than a written request, but only a FOIA response gives you an official record you can keep.
Visitation Hours and Rules
The 2024 state inspection confirms in-person visitation runs on Sundays and Thursdays, and that Combined Public Communications provides texting and kiosk video visitation. Full hour-by-hour schedules, the approved-visitor process, ID rules, and dress code were not published in official sources, so the table below reflects only the days the inspection confirmed. Call the jail to lock in exact times before you travel.
| Day | Hours | Type |
|---|---|---|
| Sunday | Confirm with jail | In-person |
| Thursday | Confirm with jail | In-person |
| Any day | Confirm with jail | Kiosk video / texting |
Because the published detail is thin, the safest step is to call 309-543-2231 before a visit. The jail can confirm the day, the visitor list, and what you may bring in.
How to Contact a Mason County Inmate
Beyond visits, the jail supports mail, phone, and video contact, though the public detail is limited. The state inspection confirms mail is reviewed under Illinois jail standards and that detainees may receive letters, with incoming mail checked for contraband. No official postcard-only rule, scanning rule, or public mailing-address format was published, so confirm the correct format with the jail before sending anything.
For phone and video, Combined Public Communications is the named provider for texting and kiosk video visitation. Local call pricing, account funding, and tablet details were not published in official county sources. The practical step is to call the jail and ask how to set up an account and what the current process is.
Commissary and Inmate Funds
The 2024 inspection lists the jail's commissary vendors as Union Supply, Keefe, Vistar, Frito-Lay, and Brockmans, and notes that meals are prepared and delivered by Havanna Health Care. It does not publish deposit fees, money-deposit methods, or a lobby-kiosk process for Mason County, so those specifics should be confirmed directly. Illinois standards do require commissary to be offered regularly, at least weekly.
Note: Confirm a person is actually in Mason County custody before sending money or scheduling a visit, since a name may have moved to state prison or another agency.
