Where to Send Mail to Someone at ASPC Florence West - Kasson (and Why It Matters)

Starting December 15, 2025, ADCRR begins centralized processing for incoming personal mail. There's a one-month grace period (December 15, 2025 through January 15, 2026) where non-legal mail mistakenly sent to a prison complex will still be processed and delivered to the inmate. After January 15, 2026, the stakes go up. Non-legal mail improperly sent to prison complexes will be returned to sender. If you want your mail to reach someone at Kasson without delays, double-check which address matches what you're sending before you drop it in the mailbox.

Starting December 15, 2025, personal mail (letters, greeting cards, photos, drawings) should go to the Digital Processing Center at PO Box 211309, Dallas, TX 75211. Include the inmate's full name and ADCRR number, plus the prison complex and assigned unit. These details connect your mail to the right person once it enters centralized processing.

1. Address personal mail to the Digital Processing Center - Use PO Box 211309, Dallas, TX 75211 and include the inmate’s full name, ADCRR number, prison complex, and assigned unit.
2. Use the Dallas address starting December 15, 2025 - That is the effective date for routing personal mail through centralized processing.
3. Know what the grace period does (and doesn’t) cover - From December 15, 2025 through January 15, 2026, non-legal mail that’s sent to a prison complex by mistake will still be processed and delivered. From January 15, 2026 onward, non-legal mail improperly sent to inmates at prison complexes will be returned to sender.

Packages go to Phoenix, not the Digital Processing Center. ADCRR's centralized address for packages is: Arizona Department of Corrections, Rehabilitation and Reentry, 801 E Jefferson Street, Phoenix, AZ 85034. Include the inmate's full name and ADCRR number, plus the prison complex and assigned unit. Publications follow the same Phoenix destination. The effective date for this Phoenix routing (for both packages and publications) is January 7, 2026. The simple rule: Dallas handles personal mail like letters and photos. Phoenix handles packages and publications.

• ✓ Address packages to: Arizona Department of Corrections, Rehabilitation and Reentry, 801 E Jefferson Street, Phoenix, AZ 85034
• ✓ Include the inmate’s full name and ADCRR number
• ✓ Include the prison complex and assigned unit
• ✓ Send publications to the Phoenix address (effective January 7, 2026)

Legal mail stays separate from the centralized system. As of 12/05/25, legal mail should still go directly to the inmate at their assigned unit. Do not send legal mail to the Digital Processing Center in Dallas or the centralized Phoenix address.

ASPC Florence West - Kasson lists this facility mailing address: PO Box 8200, Florence, AZ 85132, United States.

That Kasson PO Box is the facility's listed mailing address, but which system you use depends on what you're sending and when. For personal letters, greeting cards, photos, and drawings, routing changes on December 15, 2025. Those items should go to the Digital Processing Center in Dallas with the inmate's full name, ADCRR number, prison complex, and assigned unit. The grace period (December 15, 2025 through January 15, 2026) gives you cushion if something goes to a prison complex by mistake. After January 15, 2026, non-legal mail improperly sent to prison complexes will be returned to sender. For reliable delivery, match the item to the correct address (Dallas for personal mail, Phoenix for packages and publications) and make sure all inmate identifiers are complete.
