How to Contact an Inmate at Johnson County Adult Detention Center (KS)

General mail you send through USPS (postcards, letters, greeting cards) doesn't go directly to the facility. It's processed off-site through a service called MailGuard®, then delivered digitally to the inmate on password-protected kiosks or tablets.

Where you address your envelope depends on what you're sending. Non-privileged mail (regular letters, cards) goes here: Inmate's Name – Inmate's CFN, C/O Smart Communications, Johnson County Sheriff's Office, P.O. Box 9176, Seminole, Florida 33775-9176. Pre-approved packages, newspapers, and magazines go directly to the facility: Your Name – Your CFN, Johnson County Adult Detention Center, 101 North Kansas Ave, Olathe, KS 66061. Legal mail needs to be clearly marked as such and sent via the United States Postal Service, addressed to the inmate's name and CFN.

After you send non-privileged mail, it goes through off-site processing before being delivered digitally to the inmate's kiosk or tablet. They won't receive a physical letter.

What to Verify

• ✓ Confirm the inmate’s exact name and CFN before you mail anything
• ✓ Double-check that what you’re sending counts as non-privileged general mail versus a pre-approved package/newspaper/magazine, since they go to different addresses
• ✓ If you’re sending legal (privileged) mail, make sure it’s clearly marked as legal mail and addressed to the inmate’s name and CFN

MailGuard® is a free service. A free account lets you track delivery status, get notifications if something is rejected, and download copies of processed mail. If you're sending something time-sensitive, confirm the current process with the detention center first.
