Inmate Mail

In an effort to keep contraband out of the Lewis and Clark County Detention Center, the Lewis and Clark County Sheriff’s Office is implementing a new system for sending documents, photos and mail to inmates.

If you wish to send documents, photos and mail to inmates, we now have a quicker and more efficient method using our new Inmate Messaging system where you just go to and set up an account. You can then easily send messages to an inmate for instant delivery. You can also take a picture of any documents and attach to these messages. Messages are only $0.25 per messages and picture messages / documents are only $0.35 per picture. This is much cheaper than postage, envelopes and the time it takes to mail a letter and the inmate will receive the message and/or picture instantly. There are no limits on how many messages and photos that can be sent to inmates.

Starting July 1, 2023, all inmate mail, EXCEPT for legal and medical mail, must be mailed to the following address, PO Box 591, Longview, Texas 75606, utilizing existing Lewis and Clark County Detention Center mail rules.
