Visiting a State Prison
Visiting requires advance planning and prior approval. All visitors must submit an application and receive written approval before their first visit. Click any facility to view specific visitation guidelines and download the visitor application.
Legal Help & Appeals
Unlike jails, individuals in state prison have already been sentenced. However, if your loved one is still in pretrial or sentencing phase, a skilled criminal defense attorney can negotiate plea agreements and potentially reduce sentence length.
Calling an Inmate
Phone calls are outbound only. Your number must be registered and approved with the facility's phone provider, and a prepaid account needs to be funded. Read our inmate calling guide for setup instructions.
Sending Money
Inmates rely on commissary funds for hygiene products, food items, clothing, and phone credits. Methods include online transfers, kiosk deposits, money orders, or approved third-party services depending on the facility.
Programs & Education
Most state prisons offer rehabilitative programs including GED and literacy education, vocational training, substance abuse treatment, cognitive behavioral therapy, and religious services. Check individual facility pages for availability.
Daily Life Inside
State prisons operate on structured daily schedules including wake-up times, meal periods, work or program assignments, recreation time, and lights-out. Inmates are assigned to housing units based on security classification and behavior.
