Mail & Packages in Rhode Island (RIDOC)

A System in Transition — Check Before Mailing

Rhode Island’s current published rule, in a regulation effective July 2025, delivers original mail after it passes through a threat-detection scanner — the regulation states the scanners are not used to read or copy the text of mail. But in mid-2025, RIDOC announced plans to digitize all non-legal mail through a vendor scanning center out of state, with letters delivered as scans on tablets. As of this guide’s review date, RIDOC’s posted instructions still direct mail to the Cranston post office boxes and no address change has been published — but this is exactly the kind of change that lands suddenly. Check RIDOC’s mail FAQ page before mailing anything, especially anything original or irreplaceable.

Addressing Mail

The published format, top to bottom: the person’s full name, their ID number, their cell number and building if you know it, the facility’s post office box, and Cranston, RI 02920. Each facility receives its own mail:

• Intake Service Center — P.O. Box 8249
• High Security Center — P.O. Box 8200
• Maximum Security — P.O. Box 8273
• John J. Moran Medium Security — P.O. Box 8274
• Minimum Security — P.O. Box 8212
• Gloria McDonald Women’s Facility — P.O. Box 8312

All in Cranston, RI 02920 — a transfer between facilities means a new box number. Two format rules cause the most returns: mail must arrive in a white envelope (a rule dating to 2012; manila envelopes are accepted from attorneys), and the scanner’s published page limits are 5 pages in a standard letter envelope or 25 pages in a 10 x 13 manila envelope — longer letters split across multiple envelopes.

What Can Go in a Letter

Letters, greeting cards, and personal photographs are allowed — photos must not show nudity, and purchased commercial photographs are prohibited. Mail is distributed within 24 hours of receipt from the post office where possible, excluding weekends and holidays. There is no limit on how much mail a person can receive.

What gets mail stopped: cash, checks, or money orders (published rule: seized and deposited to the person’s account, with a receipt — but the deposit channels in Sending Money are the right way); postage stamps (commissary only); colored envelopes; anything C.O.D.; and content in the prohibited categories — coded writing, escape or weapon material, sexually explicit content. Items removed from mail are documented with written notice to the person, and rejections can be appealed through the grievance process.

Books, Magazines, and Newspapers

Hardcover books are prohibited. Paperbacks, magazines, and newspapers are allowed, subject to content review — and notably, Rhode Island publishes no publisher-direct requirement, unlike most states. Orders must be prepaid (“bill me later” orders are not accepted). Publications that fail content review go through a published multi-level appeal, and the publisher itself can request review within 14 days.

Packages

Packages come only by USPS — UPS, FedEx, and other commercial carriers are not accepted, and everything must be prepaid. Rhode Island publishes no vendor package program; property reaches the person through commissary purchases from their own account.

Legal Mail

Rhode Island’s privileged-mail list is broad — attorneys, courts, public officials, the public defender, the ACLU, and legal aid organizations among them. Privileged mail passes the threat scanner unopened and is opened for contraband inspection only in the person’s presence; the current regulation, adopted in 2025 after litigation over attorney mail handling, explicitly bars staff from reading it. Senders’ official status must be clear on the envelope to get privileged treatment.

For People Without Money

A person who is involuntarily unemployed, has under $10 in their account, and has had no deposits of $10 or more in the previous two months qualifies as indigent — RIDOC pays first-class postage for up to three personal letters a week plus all legal mail.
