How to Send Mail to Someone at Sebastian County Detention (Phoenix, MD P.O. Box Explained)

All non-legal and non-commercial mail for inmates at Sebastian County Detention Center must be mailed to: Sebastian County Detention Center, P.O. Box 247, Phoenix, MD 21131.

Mail sent to that Phoenix, MD P.O. Box doesn't go straight into the jail as a physical letter. Instead, a mail-scanning vendor processes all non-legal and non-commercial mail. Once processed, your letter is delivered electronically to the inmate through the facility's kiosks or tablets. Think of it this way: your handwritten letter gets converted into a digital message they read on a screen.

Addressing Details

• ✓ Inmate’s full first and last name (clearly printed on the outside of the envelope or postcard)
• ✓ Inmate ID number (the “Subject Number” shown in the facility’s Inmate Inquiry)
• ✓ Sebastian County Detention Center
• ✓ P.O. Box 247
• ✓ Phoenix, MD 21131

Write the name and inmate ID number clearly on the outside of the envelope or postcard. The facility uses this information to match your mail to the right person. Missing or hard-to-read details can mean your letter gets lost or sent to the wrong inmate.

Prohibited Content

• ✓ Racy or pornographic images (content violations may prevent the item from being delivered electronically to the inmate via kiosk or tablet)
