Sending Letters to the Bexar County Adult Detention Center

The Comal Street mailroom opens every letter, checks it and scans it to the inmate kiosk, where it stays viewable for up to six months. Paper originals are held two business days and then destroyed, so never mail anything you want back. Kiosk delivery runs Monday through Friday, except federal holidays.
