Who to Call or Email at Johnson County: Mail Questions, Deposits, and Appeals
Getting a mail issue resolved or putting money on someone's account goes a lot faster when you reach the right office on the first try. Here are the Johnson County contacts for mail questions, deposit help, and mailroom appeals.
For questions about inmate mail procedures, call 913-715-5900. This is the number to use if you need to confirm what's allowed, how mail gets processed, or why something isn't getting through.
If mail was returned and you want to appeal that decision, email DetentionMailroomAppeals@jocogov.org. Include clear identifying details in your message (the inmate's name, what was sent, and why you believe the item should be accepted) so it gets routed correctly.
Note: If correspondence is fully or partially rejected, the inmate will receive a written notice explaining the reason(s).
Deposit and Summit Jailatm Support
- ✓ Deposits can be made at the lobby kiosk at either jail
- ✓ The kiosk accepts cash deposits
- ✓ The kiosk accepts credit/debit card deposits
- ✓ Lobby kiosk hours are 7:00 am to 10:00 pm daily
To complete a lobby kiosk deposit, you need the inmate's six-digit Criminal File Number (CFN). Get this before you start the transaction. Otherwise you'll be stuck at the screen mid-deposit with no way to finish.
Can't get to the lobby kiosk? Friends and family can also make inmate deposits online at jailatm.com. The service runs 24 hours a day, 7 days a week, which is helpful if you need to handle a deposit outside business hours.
For help with Summit/jailatm deposits, call customer service at (866) 335-2734 (Option 1). Use this number if you're troubleshooting a deposit or need support with the deposit service itself.
