Use the WDOC offender locator for the inmate number and current facility, then WDOC Contact Us for that site’s mailing address. PP 5.401 requires the person’s confinement name with the inmate number immediately following on the first line, the facility name, then the facility address — plus your complete return address. Do not use titles, aliases, or nicknames.

Special cases

• Books, magazines, and other publications → Publisher only — not family in a letter

  Inmates may receive publications directly from the publisher only. Hard-back books are prohibited regardless of source. Family and friends cannot order publications for delivery into a facility.

• Packages from friends and family → Not permitted

  Outside friends and family are not permitted to mail packages to inmates — no exceptions (PP 5.401). Keep correspondence in a flat letter envelope within size and thickness limits.

• Legal / privileged mail → Facility, under privileged-mail procedures

  Attorney mail must be clearly marked “LEGAL MAIL” on the addressee side of the envelope (set apart from addresses). Legal and official mail is opened for contraband in the inmate’s presence and is not read unless authorized. Mail over 3″ thick is treated as a package and returned unless pre-approved (Form #522).

• Funds → Access Secure Deposits — not cash in the envelope

  Cash, checks, and money orders in the mail are contraband. Use WDOC-approved deposit channels (e.g. accesscorrections.com) instead of enclosing money with a PDF mailing.

Format & content rules

• Allowed enclosures in a personal letter include written correspondence, photocopies, small pamphlets, hand-made drawings, and personal photographs up to 8″ × 10″ — as long as total thickness does not exceed ¼″ and the envelope does not exceed 9″ × 12″ (PP 5.401 § IV.A.21).
• Printed PDF pages mailed as photocopies fit the enclosure rules above; the practical limit is thickness (¼″), not a published page count. Split very thick packets into multiple envelopes.
• Newspaper and magazine clippings and personal photographs each have a separate cap of 10 items per mailing. Self-developing photographs (e.g. Polaroid) are prohibited.
• Non-privileged mail is opened and may be read. Always put a complete return address on the envelope.
• Do not affix stickers, tape, glitter, perfume, or other uninspectable material to the envelope exterior — only postage, address labels, and return-address labels are allowed.
• Publications, sexually explicit material, gang-related content, escape instructions, and other prohibited content may be rejected or censored under PP 5.401.

Document mailing checklist

1. Confirm the person is in WDOC prison custody (not county jail) and look up their inmate number and current facility.
2. Look up the facility mailing address on WDOC’s Contact Us page (PO box when listed).
3. Print on ordinary letter paper; keep the envelope within 9″ × 12″ and total thickness at or under ¼″.
4. Address with confinement name + inmate number on line one, facility name and address below, include your return address, and mail as personal correspondence.
