How to Address Mail for Someone at Idaho State Correctional Center (ISCC)
Getting the address format right is the single most important step to making sure your letter actually reaches someone at Idaho State Correctional Center (ISCC). Here's the four-line format you need, including the ISCC PO Box and the resident's unit number.
Format your envelope with four clear lines. First line: the resident's last name and IDOC number. Second line: the facility name (ISCC) plus the resident's unit number. Third line: PO Box 70010. Fourth line: Boise, ID 83707.
Example: Resident Last Name, IDOC #123456 ISCC, Unit 1 PO Box 70010 Boise, ID 83707
The first line needs the resident's last name and IDOC number. This combination helps staff route your mail to the right person - especially when multiple residents share similar names. Keep it simple: last name first, then the IDOC number.
Note: Before mailing anything, confirm your loved one is still at ISCC and verify their current unit number. Addresses are facility-specific, and an outdated unit number can delay delivery.
ISCC residents can receive letters but not packages - stick to standard correspondence. Photos are allowed, though Polaroids and any images showing nudity are prohibited. Expect all personal mail to be opened and searched for contraband. If something in your envelope is considered unacceptable, it may be returned to you or referred to authorities.
