Missouri Prison & Jail Visitation, Phones, Packages & MailTopics / Information relating to the Missouri Department of Corrections and local / county Jail visitation, phone calls, mail, inmate care packages, etc.
If you are filling this out at a local agent, the person there should know what your code is. I know that when I first started sending money that way, the agent was always very helpful. If you are doing this online, maybe you could call a local agent in your area.
I am no longer actively involved with the prison system or anyone inside. Please contact an active member for up to date info. All the best, Amy
