FCI Seagoville Mail & Photos

Every piece of mail must include the inmate’s full legal name and register number on the envelope and, for photos, inside the envelope too. All mail is inspected by staff before delivery. Standard print photos are allowed; Polaroids, glitter, stickers, and embedded objects are not.

Correct format:

[Inmate Full Legal Name]

Your return address is required in the upper-left corner. Mail without a return address is rejected outright. Mail arriving without the register number is often returned or delayed while staff tries to match it: don’t skip it.

Letters

Standard letters on plain white or lined paper are accepted. You can use a greeting card as long as it has no embedded objects (glitter, foil embellishments, pop-ups, perfume). Envelopes must be plain white or manila: no padded envelopes for general correspondence.

All incoming correspondence is subject to review by BOP mail room staff.
