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

Mailing someone at ASPC Florence West - Kasson? The address depends on what you're sending. Most personal mail - letters, greeting cards, photos, and drawings - goes to ADCRR's Digital Processing Center in Dallas, not to the prison itself. Packages and publications use a different centralized address in Phoenix. Legal mail is handled separately and still goes to the person at their assigned unit. Send to the wrong address, and your mail could be delayed or returned.

• ✓ Personal mail (letters, greeting cards, photos, drawings) → Digital Processing Center: Arizona Department of Corrections, Rehabilitation and Reentry; Inmate’s Full First and Last Name + ADCRR Number; Prison Complex, Assigned Unit; PO Box 211309; Dallas, TX 75211
• ✓ Packages → Arizona Department of Corrections, Rehabilitation and Reentry; Inmate’s Full First and Last Name + ADCRR Number; Prison Complex, Assigned Unit; 801 E Jefferson Street; Phoenix, AZ 85034
• ✓ Publications (effective January 7, 2026) → Arizona Department of Corrections, Rehabilitation and Reentry; 801 E Jefferson Street; Phoenix, AZ 85034
• ✓ Legal mail → Sent to the inmate at their assigned unit

Personal mail - letters, greeting cards, photos, and drawings - goes to ADCRR's Digital Processing Center, not directly to ASPC Florence West - Kasson. This applies to all incoming mail (except legal mail, parcels, publications, and official government mail) starting December 15, 2025. If you're writing around that changeover date, pay close attention to the grace period below. Getting it right means the difference between your mail being processed or sent back.

Format personal mail like this: Arizona Department of Corrections, Rehabilitation and Reentry Inmate's Full First and Last Name + ADCRR Number Prison Complex, Assigned Unit PO Box 211309 Dallas, TX 75211 That middle section matters. Include the inmate's full name, their ADCRR number, and their prison complex/assigned unit - staff need all of it to route your mail correctly.

Packages go to a centralized Phoenix address - not the Digital Processing Center. Send a package to the digital mail center, and it won't be accepted. Use the Phoenix address below instead. Make sure your label includes the inmate's full name, ADCRR number, prison complex, and assigned unit.

Include the inmate's full name, ADCRR number, and their complex and assigned unit so it gets routed correctly.

ASPC Florence West - Kasson's facility mailing address is: PO Box 8200 Florence, AZ 85132 United States This is still the facility's official address, but for most incoming personal mail (letters, cards, photos, drawings), ADCRR directs you to use the Digital Processing Center address instead.

Practical Tips

• ✓ Put the inmate’s full name and ADCRR number on everything you send, and include the prison complex and assigned unit (this is required for the Digital Processing Center and the Phoenix centralized address).
• ✓ For personal mail (letters, greeting cards, photos, drawings), use: PO Box 211309, Dallas, TX 75211.
• ✓ Don’t send packages to the Digital Mail Processing Center - packages must go to: 801 E Jefferson Street, Phoenix, AZ 85034.
• ✓ Publications must go to: 801 E Jefferson Street, Phoenix, AZ 85034 (effective January 7, 2026).
• ✓ Watch the key dates: Digital Processing Center for incoming non-legal mail is effective December 15, 2025.
• ✓ If you accidentally send non-legal mail to the prison complex during the grace period (December 15, 2025 through January 15, 2026), it will still be processed and provided to the inmate.
• ✓ After January 15, 2026, non-legal mail improperly sent to inmates at prison complexes will be returned to sender - so double-check the address before you mail it.
