How to Mail a Letter to an Inmate at the Johnson County Jail

[Inmate's full name]
PO Box 2540
Iowa City, IA 52244

Kunkel's Jail Division FAQ prints this box number; the 511 S. Capitol St. building address is for visitors. Iowa City letters are opened by jail staff, not a scanning vendor, so attorneys, publishers and family all use PO Box 2540 with the inmate's complete name. Put your full name and address in the return corner; letters with stickers, lipstick, perfume or any other substance on the paper or envelope are refused. Reading material reaches PO Box 2540 only when a publisher ships it, and boxes of any other kind come back.

What can you mail to an inmate in Johnson County Jail?

Plain letters written on paper are what PO Box 2540 accepts; keep cards free of stickers, scents and decorations, and have reading material shipped by its publisher.
