How to Send Mail to Someone at USP Florence ADMAX: Address Formats That Actually Work

For regular letters to someone at the main USP, the first line matters most: write the incarcerated person's name and register number exactly as the Bureau of Prisons has it listed. INMATE NAME & REGISTER NUMBER USP Florence High PO BOX 7000 Florence, CO 81226

Writing to someone at the satellite camp? Use the same name-plus-register-number format, but add "SATELLITE CAMP" to the address. This label ensures proper routing. INMATE NAME & REGISTER NUMBER SATELLITE CAMP USP Florence High PO BOX 7000 Florence, CO 81226

For the Federal Satellite Low (FSL), include "FEDERAL SATELLITE LOW" along with the inmate's name and register number. Keep both exactly as provided - small mismatches can slow things down. INMATE NAME & REGISTER NUMBER FEDERAL SATELLITE LOW USP Florence High PO BOX 7000 Florence, CO 81226

Freight shipments and non-USPS parcel deliveries work differently than regular mail. For USP Florence ADMAX, include a staff name and the line "ATTN: WAREHOUSE." For FSL shipments, the attention line should read "FEDERAL SATELLITE LOW ATTN: WAREHOUSE." You're routing the delivery to the warehouse under a staff name - not addressing it like standard inmate correspondence.

• ✓ Use the inmate correspondence format (inmate name + register number, plus the correct unit label) for regular letters sent through USPS.
• ✓ Use the freight/non‑USPS format when a shipment is going through a non‑USPS carrier or is considered freight.
• ✓ Freight/non‑USPS parcels must include a staff name and “ATTN: WAREHOUSE” (or “FEDERAL SATELLITE LOW ATTN: WAREHOUSE” for FSL).

All incoming mail gets opened and inspected by staff. At BOP facilities, general correspondence is checked for contraband and anything that could threaten institutional security or order.

Some mail qualifies as "special mail," but only if it's properly marked. When marked correctly, it can only be opened with the inmate present. Staff will still inspect it for physical contraband and verify that any enclosures actually qualify as special mail.

The default rule for packages from home: don't send it unless it's approved. Inmates cannot receive home packages without prior written approval from their unit team or another authorized staff member. Without that approval, the only exceptions are release clothing and authorized medical devices.

Books and magazines follow their own rules: they must come directly from the publisher or an approved commercial vendor - not from family or friends. This "publisher-direct" requirement is what keeps reading material from being rejected as an unauthorized home package.
