Find the current Kansas facility mailing address
Kansas personal letters go directly to the resident's current correctional facility. Confirm the institution and KDOC number, then use its published mailing address rather than a visiting, delivery, money, or central-office address.
The resident's full name and KDOC registration number and the sender's name and address are mandatory. A letter missing this information will not be delivered.

Common questions
How do I send a letter to someone in Kansas state prison?
Use KASPER to confirm the resident's KDOC number and current facility, then write online with that facility's mailing address. PieterPost formats, prints, envelopes, adds postage, and mails the physical letter.
Which address should I use for Kansas inmate mail?
Kansas does not publish one statewide address for personal letters. Use the resident's full name and KDOC number, current correctional facility, and that facility's published mailing address.
How do I find the KDOC number and current facility?
Search KASPER for the resident's current institution and KDOC number. Recheck after a transfer because Kansas letters are delivered directly to the named facility.
Which details are required on a Kansas prison letter?
The full resident name and KDOC registration number are mandatory, as are the sender's name and address. A letter missing the required resident or sender information will not be delivered.
Does this guide apply to Kansas jails or federal prisons?
No. This guide covers adults in Kansas Department of Corrections state prisons. County or city jails, federal prisons, juvenile facilities, and community-corrections settings can have different mailing guidance.
