Maryland Inmate Phones/Sending Money & Mail

Sending Mail to Inmates in Maryland Prisons

Anyone incarcerated in a Maryland prison is allowed to send and receive correspondence.  Inmates must pay their own postage unless they are deemed indigent, in which case they are provided postage and writing materials for sending up to seven letters every week.  To qualify as indigent the inmate must have had less than $4.00 in their account for over 30 days.  All incoming mail can be opened and inspected for contraband.  You may not send cash, stamps, or any other items with your correspondence.  Mail will be read if it is believed to contain escape plans, describes the use or construction of weapons, bodily harm, procedures for manufacturing drugs or alcoholic beverages, is written in code, or poses a direct threat to the safety and security of the facility.

You can also send inmates 4"x6" photos.  The photos cannot be Polaroid or instant photos as these could be used to introduce contraband to the facility.  You should send no more than five photographs at a time.  The photos must not contain nudity or depict any illegal activities.  Refrain from sending pictures that contain hand gestures and tattoos as these can be misconstrued as gang symbols.

Whenever you send mail to an inmate you should always address it as follows:
Inmate Name, ID Number
Facility Name
PO Box or Street address
City, State, Zip code

Sending Money to Inmates in Maryland

Inmates incarcerated in Maryland have two types of accounts, a reserve account and an active account.  The reserve account contains funds the inmate is not allowed to spend, the active account contains money the inmate can use to purchase items from the commissary.

  • To send funds to an inmate you will need to get a United States Postal Money Order made payable to the inmate.  You should also include the inmate's full name and institution SID number on the money order.  Money orders over $250 are held for 30 days, otherwise it will take up to five business days for the money order to be processed.  Where you send funds will depend on which institution the inmate is located in.  If your inmate is in one of the following institutions you will need to send the money order to the Lockbox:
