How to send messages, photos, and packages
Use the mailing address on Sandstone FCI's official facility page for letters and standard parcels—follow it exactly to avoid delays. Sending freight or using a non-USPS carrier? Don't guess. Sandstone provides separate shipping instructions and addresses on the same facility page. For most people, USPS is the simplest option. Include the incarcerated person's full name and any required identifiers. Incoming mail gets inspected for contraband, and in Minnesota it may be opened, scanned, and delivered digitally. The original might not come back, so keep copies of anything important. Don't send cash through the mail. And confirm carrier or scheduling rules before shipping non-USPS packages.
Search for a loved one and send messages and photos in minutes.
