Letters for Clayton County Jail Inmates

Clayton County routes inmate letters through a Saint Olaf post office box, so the 230th Street address is not used for them:

[Inmate's full legal name]
Clayton County Jail
P.O. Box 10
Saint Olaf, IA 52072

Staff open each item and pull out contraband before handing it over. Every envelope needs the writer's name and return address; ink, greeting-card and photograph rules can be confirmed through 563-245-2422. Letters to Box 10 should carry words and approved photos only; the Clayton County money guide explains the accepted ways to add funds instead of slipping currency or a personal check inside an envelope.
