Send to the institution instead

• Privileged / attorney-client legal mail → Secure.li electronic upload (not postal mail)

  Effective July 1, 2026, privileged attorney-client documents received at an institution are returned to the attorney. Attorneys must upload privileged PDFs through Secure.li (free) or bring documents on a visit for copying. Register at doc.mo.gov/legal-mail.

• Non-privileged attorney correspondence → Digital Mail Center (Tampa address above)

  Attorney mail that is not privileged client communication follows the same Tampa scan process as personal mail.

• Certified mail → Offender’s institution (case-manager pre-approval required)

  No personal correspondence via certified mail. Pre-approved items may include release identification or legal documents needing the offender’s signature.

• Publications (books, magazines, newspapers) → Institution — from publisher, distributor, or bona fide vendor only

  Do not include publications in a personal Tampa envelope. See MODOC reading-material guidelines.

• Visitor applications → Institution mailing address

  Visitor paperwork is not processed at the Digital Mail Center.

• Agency mail (e.g., Children’s Division, Child Support) → Institution

  Certain official agency correspondence is still accepted at facilities — not the Tampa scan center.

Format & content rules

• Accepted for scanning: letters/correspondence, postcards, pictures, and drawings. Printed PDF pages mailed as correspondence fit this category.
• Maximum 10 items per envelope — each letter, postcard, picture, or drawing counts as one item. Numbering pages is encouraged.
• Mail must contain only items that can be easily scanned; hard-to-scan items may be delayed or returned.
• Always include a complete return address and enough identifying information (name + DOC ID) for staff to match the offender.
• Handwritten correspondence should use blue or black ink. Avoid felt-tip pens, markers, paint, glitter, or ink that bleeds through paper.
• No labels, stickers, or stamps inside the envelope (postage on the outside is fine).
• Greeting cards sent through postal mail cannot be scanned and will not be delivered — use Securus JPay for cards, photos, and short videos.
• Prohibited content includes nudity, sexually explicit writing, gang depictions, tattoo patterns, collages, two-ply or altered photos, screen shots of texts/social media, catalogs, and calendars.
• Do not enclose cash, checks, money orders, stamps, stamped envelopes, food, or clothing.
• Optional: include a self-addressed stamped envelope if you want originals returned; otherwise scanned mail is held 45 days then discarded. To request return from Securus, call (800) 844-6591.
• If any piece of a mailing is rejected, the entire mailing may be rejected.

Document mailing checklist

1. Confirm the person is in MODOC custody and look up their DOC ID (offender number).
2. Keep the envelope at or under 10 items — a multi-page printed letter is typically one correspondence item, but split mixed mailings (letters + many photos) across envelopes if needed.
3. Print on ordinary scannable paper; avoid staples, tape, glitter, or non-paper inserts.
4. Address to the Tampa Digital Mail Center with offender name + DOC ID and your return address — not the prison facility.
