Everything Families Must Know About Utah DOC’s New Mail System (Effective Jan 5, 2026)

Starting January 5, 2026, all personal (non-legal) mail will be processed and delivered by UDC's own mail processing centers, replacing the current third-party service. Physical mail gets scanned and delivered as printed copies. That means incarcerated people will not receive original documents or original photos.

Starting January 5, 2026, all incoming non-legal mail must include the incarcerated person's full name and Inmate ID, and it needs to go to the correct facility PO Box. Use the addresses exactly as listed: Utah State Correctional Facility, Incarcerated Person's Name – Inmate ID #, PO Box 165300, Salt Lake City, UT 84116. Central Utah Correctional Facility, Incarcerated Person's Name – Inmate ID #, PO Box 550, Gunnison, UT 84634. Attorneys can also send privileged legal mail directly to the facility using these same PO Box addresses.

UDC's mailroom will process no more than five pages per mailing. If your envelope has more than five pages total, it gets denied. The incarcerated person receives a denial slip, and the envelope comes back to you. "Per mailing" means everything in that one envelope counts, including any extra printed pages you tuck in with your letter.

Letters must be typed or handwritten on only one side of 8.5 x 11-inch paper. Mail them in a standard #10 envelope (4 x 9½ inches). Other envelope sizes won't be accepted. Postcards, greeting cards, and similar items are also not permitted under the new rules, even if they'd normally fit inside your envelope.

• ✓ One-sided 8.5 x 11-inch pages (typed or handwritten)
• ✓ Standard #10 envelope (4 x 9½ inches)
• ✓ Do not send postcards
• ✓ Do not send greeting cards (or similar card-style items)
• ✓ Do not use non-standard envelope sizes (anything other than a #10)

If you want to send photographs, you'll need to use one of three approved third-party vendors: Pelipost, Ameelio, or Flikshop. Photos and other physical mail are scanned, then printed in color for delivery. The incarcerated person receives the printed copy, not the original.

Attorneys can send privileged legal mail directly to the UDC facility for delivery to incarcerated clients. Use the facility PO Box for the correct location: Utah State Correctional Facility, PO Box 165300, Salt Lake City, UT 84116, or Central Utah Correctional Facility, PO Box 550, Gunnison, UT 84634. If you're an attorney sending time-sensitive material, confirm current handling requirements before mailing.
