How Missouri inmate mail works

  • All personal mail for Missouri offenders goes to the Securus Digital Mail Center in Tampa, Florida — not the prison. Mail sent to the institution is not processed.
  • Address it to the offender’s full name and DOC ID number, c/o the Digital Mail Center, then the PO box. Include your full first and last name and return address.
  • Personal mail is opened and scanned; the offender views it on a media player. Scanned mail is held about 45 days, then discarded — it is not returned unless you enclose a self-addressed stamped envelope.
  • No more than 10 items per envelope, and only things that scan cleanly. Write in blue or black ink.
  • Greeting cards are not accepted by mail — they can be sent through Securus (securustech.net).

What you can't send

  • Cash, checks, money orders, gift cards, or postage stamps
  • Greeting cards (send these through Securus instead)
  • Any object other than paper (no polaroids, laminated items, or enclosures)
  • Nude, sexually explicit, or obscene photos
  • Stickers, glitter, glue, tape, perfume, lipstick, or crayon/marker

Photos: Photos and drawings are scanned and shown on the offender’s media player. Keep to the 10-items-per-envelope limit and avoid nudity or explicit content.

Books & magazines: Books and publications are not sent to the Digital Mail Center; they must be ordered from an approved publisher or vendor under MODOC policy.
