St Clair County Jail, Belleville, IL

St Clair County Jail in Belleville has set visiting hours and a few rules worth knowing before you go. In-person visits run Monday–Friday 11:00 am–7:00 pm and Saturday–Sunday 9:00 am–7:00 pm. Remote video visitation is available daily from 11:00 am to 7:00 pm. You're limited to two twenty-minute in-person visits per week. Bring a current photo ID and make sure you're on the inmate's approved visitors list before trying to schedule. Children 16 and younger must come with a parent or legal guardian. The jail posts specific clothing restrictions—if your outfit doesn't meet the guidelines, you won't get in. Expect searches on arrival, and schedule ahead using the facility's approval process.

St Clair County Jail handles online communication through SmartInmate (Smart Communications). The vendor offers free signup for friends and family. The jail publishes multiple phone numbers—lines for the front desk (plus an alternate), booking/intake/classification, the Smart Communication vendor line, property storage, and a toll-free option. Phone calls, video visits, and electronic messages are monitored and recorded, which is standard for Illinois facilities. Both the incarcerated person and their contacts need approval to communicate. To get started, create an account with SmartInmate and complete any identity or visitor verification they require. For video visits, use the vendor's system or app—not the jail's phone lines. Download it early, test it, and log in a few minutes before your appointment.

St Clair County Jail processes incoming mail through Smart Communications, a system that took effect June 20, 2022. The jail also lists an alternate mailing address in Belton, Texas for certain deliveries—double-check which address applies before sending anything. Sign up for MailGuard Tracker to follow delivery and confirm arrival. Personal mail is typically opened, inspected, and scanned into PDF images so the inmate can view it digitally. If the inmate doesn't have tablet access, the facility may provide paper photocopies. Inmates can request physical copies or originals, but scanned originals generally can't be returned.

Start with St Clair County Jail's official contact page. Most Illinois county jails list phone, fax, mailing address, and email for different needs—general questions, records requests, and more. Don't stop at the first number you see: some counties publish multiple lines (front desk, booking/intake/classification, property storage) and may include a toll-free option. Check every listing. Looking for spiritual support? Community or faith-based providers sometimes publish chaplain or ministry contact information that families find helpful. For urgent public-safety emergencies, call 911—not the jail's main number. When reaching out, include your contact information plus the incarcerated person's full name and any ID or booking number.
