County & city jails

Local jails that accept standard letter mail at their own address — each with its own rules. (Jails that only take postcards or route mail through a scanning vendor aren't listed, since a letter to those is rejected.)

Addresses and mail rules are verified against official Department of Corrections, Bureau of Prisons, and county sheriff sources and re-checked periodically. Facilities transfer and release people without notice, and mail policies change — always confirm the person's location and the current rules on the official site before mailing.
