Sonoma County Jail Mail Changes: Transition to Pigeonly for Non-Privileged Mail (Sept–Oct 2025)
Sonoma County is changing how regular mail works at its detention facilities this fall. Starting September 1, 2025, all non-privileged mail must go through Pigeonly — you can no longer send it directly to the jail. After October 1, 2025, any non-privileged mail that still shows up at the facility gets returned to sender.
