Mail, photos, messaging, and phone/call options for staying in touch.
Personal correspondence to ODaniel Unit goes through TDCJ's centralized digital mail processing. Address your envelope to the inmate's full name and TDCJ number, then mail it to PO Box 660400, Dallas, TX 75266-0400. The central processing vendor sorts and screens incoming mail—accepted pages are scanned and delivered electronically to the inmate's secure tablet or handled by facility staff. Legal mail, privileged mail, media mail, and publications sent directly by a publisher follow separate delivery paths and may skip the general scanning process. Don't send trust fund deposits or account payments to the unit; use the Inmate Trust Fund mailing instructions instead. Avoid prohibited items like cash, loose stamps, food, and personal property to prevent delays.
