Idaho's largest prison, a multi-custody men's facility in the South Boise complex in Kuna that the state has operated since 2014.

Overview

Idaho State Correctional Center (ISCC, also referred to as ICC) is a state prison for men operated by the Idaho Department of Correction (IDOC). It is in Kuna, in Ada County, within the South Boise prison complex on Pleasant Valley Road. With about 2,128 beds, it is the largest prison in Idaho. The facility holds men at minimum, medium, and close custody.

The Idaho Department of Correction uses the term “resident” for people in its custody.

What Makes Idaho State Correctional Center Different

ISCC is the largest prison in the Idaho system and houses men across three custody levels — minimum, medium, and close.

The facility opened in 2000 as the Idaho Correctional Center (ICC), the state’s first private prison, operated by Corrections Corporation of America (now CoreCivic). The state assumed operations in 2014, and the facility is now state-operated.

Visiting

The statewide IDOC visiting rules — the approved-visitor-list process, the dress code, ID requirements, and item limits — apply at Idaho State Correctional Center. Visiting is arranged with the facility, and an approved application is required first. Visiting days, hours, and whether a visit must be booked in advance are set per facility, so families confirm the current schedule with the institution before traveling. See the Visiting in Idaho guide for the approval process and rules.

Mail

Idaho does not use an off-site mail vendor for its state prisons. Incoming personal mail goes directly to the facility, where staff inspect it before delivery. Personal mail for ISCC goes to the Boise PO Box, not the Kuna street address. Address personal mail with the resident’s committed name and IDOC number:

[Resident’s full name and IDOC number] Idaho State Correctional Center PO Box 70010 Boise, ID 83707

Books and publications must come directly from a publisher or an approved vendor. See the Mail & Packages guide for the full rules on what can be sent and what gets rejected.

Phones, Tablets, and Money

Phone service runs through ICSolutions, and tablet services run through ViaPath. Trust deposits are made through Access Corrections. See the Phone & Video Calls and Sending Money guides for accounts, rates, and how to add funds.
