Mason County IL Jail is a county-operated detention center located at 102 West Market Street in Havana, Illinois. The facility holds up to 42 inmates at one time and serves as the main holding location for people arrested in Mason County. Families, attorneys, and the public can look up inmate information using the jail’s official online database or by calling the administrative office. The system shows real-time data including mugshots, criminal charges, bail amounts, bond conditions, arrest details, and active warrants. All records update within two hours of a new booking, ensuring fast access to accurate information.
How to Search for an Inmate in Mason County IL Jail
People can search for inmates in two ways: online or by phone. The Mason County Sheriff’s Office runs a 24-hour online portal that displays current inmate details. Users can view a detainee’s photograph, list of charges, bail amount, bond rules, and arrest facts. The site also shows the latest booking date, jail location, and supervising officer’s badge number. For those who prefer calling, the jail’s main number is 309-543-2231. Callers must provide the full first and last name or a government-issued ID and birthdate. The clerk checks the secure database and gives back confirmed details quickly. This service runs during regular business hours, Monday through Friday, from 7 a.m. to 5 p.m.

Online Inmate Database Features
The online database offers several helpful features. It refreshes every two hours, so users see the most recent bookings right away. Each profile includes a mugshot, which helps families confirm they have the correct person. The charge list shows all current offenses, including misdemeanors and felonies. Bail and bond details tell users how much money is needed for release and any special conditions. The system also lists active warrants, so users know if the person is wanted for other crimes. Booking dates and housing locations help track where someone is held inside the jail. Badge numbers of supervising officers add transparency and accountability.
Phone-Based Inmate Lookup
Not everyone has internet access, so phone lookup is important. The jail’s administrative office handles these requests during weekday business hours. Callers should be ready with the inmate’s exact name or their ID number and birthdate. The clerk verifies the request against the secure system and returns confirmed data in minutes. This method works well for urgent cases, like when a family member needs to post bail fast. It also helps people who are not comfortable using computers. The phone line is staffed by trained personnel who follow strict privacy rules to protect inmate rights.
Statewide Inmate Search Options
Some inmates may be transferred to state prisons. For those cases, Illinois offers a statewide search tool. Residents can call 217-558-2200 to get information from the Illinois Department of Corrections. This service gives the inmate’s full legal name, DOC ID number, current housing unit, projected release date, and parole eligibility. Law enforcement agencies use a separate toll-free line, 1-888-446-9103, to access case files and sentencing summaries. These tools help families track loved ones who move from county jails to state facilities.
