Key facts

  • Send mail to Maryland Correctional Training Center, 18800 Roxbury Road, Hagerstown, MD 21746 — the institution's inmate-mail address, not its street address.
  • Maryland delivers mail to each facility directly (it is one of the states that still delivers letters as sent, not through a scanning vendor). Address it to the incarcerated person’s full name and SID number, then the facility name and its mailing address.
  • Incoming mail is opened and inspected for contraband, then delivered. Every envelope must also show the sender’s name and return address.
  • Use a plain envelope and paper — nothing glued, taped, or attached, and no paint, marker, glitter, lipstick, scent, or liquid stain.
  • Send only through the U.S. Postal Service. Money for a person’s account is not sent with a letter; it goes to the DPSCS lockbox, not the facility.
  • PostPal prints and mails your letter for you the next business day for $5 — with your return address printed so the inmate can write back, and no printer, envelope, or stamp needed.

How to send your letter

  1. 1

    Confirm the person is still at Maryland Correctional Training Center

    Inmates are transferred between facilities without notice. Confirm they are still at Maryland Correctional Training Center — and double-check the SID number — before you mail anything, using the Maryland DPSCS's official inmate locator.

  2. 2

    Address it exactly

    First line: the inmate's full committed name and SID number. Then Maryland Correctional Training Center, 18800 Roxbury Road, Hagerstown, MD 21746. Add your full return address.

  3. 3

    Keep the contents allowed

    Plain letter-size paper is safest. Do not enclose cash, stamps, gift cards, or any object other than paper — prohibited items get the whole letter rejected. Check the mail rules above before adding photos.

  4. 4

    Send it without a printer

    Write or upload your letter to PostPal with this address prefilled, and we print, envelope, and mail it via USPS the next business day for $5 — your return address printed so they can reply.
