Key facts

  • Send mail to Santiam Correctional Institution, 4005 Aumsville Highway SE, Salem, OR 97317 — the institution's inmate-mail address, not its street address.
  • Oregon sends mail to each institution directly. Address it to the adult in custody’s full name (as it appears on DOC records — no nicknames) and Oregon SID number, then the facility’s own address.
  • Include your full name and return address. Mail without the SID number or a return address can be rejected.
  • Since January 2025, incoming mail must be in pen, pencil, typewriting, or photocopy — no colored pencil, marker, or crayon, no colored paper, and no paper heavier than standard weight.
  • Confirm the person’s current institution on DOC’s Adult in Custody Lookup before mailing. Oregon plans to move most personal mail to scanned/digital delivery near the end of 2026, so verify the current method before a time-sensitive letter.
  • 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.

  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.
