Topic Overviews

Communication

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 & Letters

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.

Sending Money

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.

Inmate Lookup

To find someone at Knox County Detention Center, start with the online inmate lookup. Alphabetic quick links let you jump straight to a last-name section. Each roster entry shows bond details, including bond type and amount for each charge. Watch for special-status notes: inmates held for immigration (ICE) are flagged, and temporary holds—like 24-hour holds—may include an end timestamp showing when they expire. Some entries also list conditional-release requirements, such as GPS monitoring before release. Rosters can change without notice, so if something looks off or missing, check recent booking/admit-release views or call the jail records desk to confirm.
