How to send your letter

  1. 1

    Confirm the person is still at Souza-Baranowski Correctional Center

    Inmates are transferred between facilities without notice. Confirm they are still at Souza-Baranowski Correctional Center — and double-check the commit number — before you mail anything, using the Massachusetts Department of Correction (DOC)'s official inmate locator.

  2. 2

    Address it exactly

    First line: the inmate's full committed name and commit number. Then Souza-Baranowski Correctional Center, P.O. Box 8000, Shirley, MA 01464. 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.
