Facility Mailing and Service Information
Maricopa County Sheriff's Office jail mail is centralized for county inmates. Non-legal personal correspondence is generally restricted to standard postcards; photographs are handled separately under MCSO rules.
Verify the person's current MCSO custody status and booking number before mailing. Because Maricopa County operates multiple jail facilities, mail is routed through the county's centralized inmate-mail address rather than assuming the physical housing facility is the mailing destination.

About Maricopa County Jail
