How Massachusetts inmate mail works

  • Massachusetts sends mail to each facility directly. Address it to the incarcerated person’s full name and commit number, then the facility’s own mailing address (a P.O. box for most, a street address for some).
  • Include your full name and return address. Mail without the commit number or a return address can be rejected (governed by 103 CMR 481).
  • Incoming non-legal mail is opened and inspected for contraband before delivery; only letters, approved photos, and postcards are accepted — no enclosed items.
  • Confirm the person’s current facility before mailing — people are transferred between prisons without notice.

What you can't send

  • Cash, checks, money orders, or postage stamps
  • Anything other than paper (no polaroids, stickers, glitter, or enclosures)
  • Nude, sexually explicit, or contraband-promoting content
  • Glued items, scented or altered paper, lipstick, or crayon/marker
  • Publications not sent directly from a publisher or approved vendor

Photos: Approved photos are generally allowed; no polaroids, and nothing nude or sexually explicit.

Books & magazines: Books and magazines must be sent directly from a publisher or major vendor, not in personal mail.
