Mailing Letters vs. Sending Packages to FCI Sandstone: Addresses and What’s Different

FCI Sandstone separates everyday inmate mail from freight-style deliveries, and the addresses are not the same. For regular correspondence and parcels, use the inmate correspondence address shown on the facility's page. The format also changes depending on where the person is housed (main institution, camp, or FSL), so copy the address exactly as listed for your loved one.

Sending freight or using a carrier other than USPS? FCI Sandstone has a separate "freight & non-USPS parcels" address listed on the facility page. Give that address to your carrier, not the inmate correspondence address you'd use for letters.

• ✓ Confirm the carrier can deliver to the freight and non-USPS parcels address listed on the FCI Sandstone page.
• ✓ Include the required inmate identifiers (name and register number) as directed for the facility’s mail formatting.
• ✓ If you’re unsure whether your shipment counts as “freight” or “non-USPS,” call the facility to confirm before you ship.

For inmate correspondence and parcels, include the incarcerated person's name and register number. If the facility shows different formatting for the main institution, camp, or FSL, use the exact label that matches where your loved one is housed.

Money and commissary deposits work differently than letters and packages. FCI Sandstone directs all mailed funds to a processing center in Des Moines, Iowa. Do not send money to the facility address you'd use for correspondence.

Before mailing anything, double-check you're using the right address. FCI Sandstone lists separate instructions for inmate correspondence versus freight and non-USPS parcels, and the formatting varies by housing location. If you want to confirm details before sending something (or before visiting), call ahead at 603-342-4000.
