Key facts

Send mail to Mission Creek Corrections Center for Women, 3420 Northeast Sand Hill Road, Belfair, WA 98528 — the institution's inmate-mail address, not its street address.
Mission Creek Corrections Center for Women is a women's facility. Address mail to the woman's full committed name and DOC number.
Washington sends mail to each prison directly. Address it to the incarcerated person’s full committed name and six-digit DOC number, then the facility’s own mailing address (a P.O. box for some, a street address for others).
A return address with an identifiable last name is required on every envelope. Mail without the DOC number or a return address is rejected and returned.
Incoming mail is opened and inspected; as of August 2026 some facilities photocopy incoming personal mail (via TextBehind) and deliver a copy — but you still mail the facility’s own address, not a vendor.
Confirm the person’s current facility on DOC’s inmate search before mailing, and note the unit — Monroe Correctional Complex uses a different P.O. box for each unit (IMU, MSU, SRTC, TRU).
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.
