Knox County Detention Center, TN

Knox County Detention Center uses JailATM for both messaging and video calls. To schedule a video session, sign in to JailATM, click Calling, then choose Schedule a Call. For messaging, you'll need a Messaging Subscription to fund outgoing messages or open collect messages—enabling it adds $5.00 in messaging credits to your account. The facility also works with CorrectPay for commissary deposits and video visit scheduling, and Securus Video Connect offers a web-based option for joining video sessions via app, computer, or tablet. Since vendor features and payment methods vary, set up your account and confirm requirements before scheduling.

Mail at Knox County Detention Center goes through screening and may look different than you expect. The facility's published PDF lists approved book publishers you can contact to send books: Penguin Random House, HarperCollins, and Simon & Schuster. For letters and photos, incoming correspondence is inspected for contraband, scanned, and delivered electronically to the inmate through a tablet or kiosk—usually within a few business days. Legal mail follows separate procedures: it's marked, verified, and typically opened in the inmate's presence for contraband screening. Staff also inspect outgoing mail. Prohibited content or contraband can result in items being returned, confiscated, or investigated. On your envelope, include the inmate's committed name, their TDOC ID# exactly as written, and the facility name to ensure proper routing.

Knox County Detention Center uses JailATM for electronic deposits. To send money, sign in, choose "Send Money Now," pick the state and facility, then search for the resident by last name or ID. Enter the amount and payment details, accept the terms, and submit. JailATM accepts Visa and MasterCard—prepaid cards won't work. Some accounts require a Social Security Number and ID verification before you can deposit. There's a $300 weekly limit per resident (Sunday through Saturday). Most transfers post within 24–48 hours. If the deposit still doesn't show after that, contact the facility so staff can check the transaction. If it isn't resolved within 72 business hours, JailATM will open an investigation.

For inmate-related questions at Knox County Detention Center, Knox County provides an Inmate Services phone number—check the county or detention center website for the current listing before you call. You may see several contacts (main line, inmate services, records, dispatch), so use a non-emergency number for routine questions and save 911 for true emergencies. Don't rely on a general contact form for urgent matters. Have the inmate's full name and a second identifier (like date of birth) ready, plus your name and callback number. If a JailATM deposit doesn't show up within 24–48 hours, contact the facility so staff can open an investigation. The custody roster may also show temporary holds with an end timestamp.
