Oregon state-prison addresses

Find the current Oregon facility mailing address

Oregon letters go directly to the adult in custody's current facility. Confirm the record name, SID number, and facility mailing address before using the rules that took effect January 13, 2025.

Oregon does not direct ordinary letters to a statewide off-site processor. Use the facility's correspondence address, not a visiting, money, delivery, or central-office address.

Common questions

How do I send a letter to someone in Oregon state prison?

Use Oregon's adult in custody lookup to confirm the record name, SID number, and facility. Enter that facility's current correspondence address when writing online, and PieterPost will format, print, envelope, add postage, and mail the letter.

Which address should I use for Oregon inmate mail?

Oregon has no universal personal-mail address. Use the name exactly as shown in Oregon DOC records followed by SID and the number, then the correct facility name and complete facility mailing address.

How do I find the SID number and current facility?

Use the Oregon adult in custody lookup to verify the SID number and current facility. Recheck after a transfer because Oregon ordinary mail is delivered directly to the named institution.

What changed under Oregon's January 13, 2025 mail rules?

The current rules took effect January 13, 2025. Letters must use white paper weighing 20 pounds or less and pen, lead pencil, typewriting, or photocopy. Cardstock, marker, crayon, greeting cards, and postcards are not allowed.

Does this guide apply to Oregon jails or federal prisons?

No. This page covers adults in Oregon Department of Corrections state prisons. County or city jails, federal prisons, juvenile facilities, and other custody settings can use different addresses and rules.
