How to confirm the current facility

  1. Open the parent Multnomah County inmate-search guide and identify the responsible sheriff, corrections department, detention center, regional jail, state agency, or other custodian.
  2. Use the verified custody method linked above.
  3. Confirm the exact facility name, booking or inmate number, current status, and jurisdiction.
  4. Open the official facility or agency page before sending mail, money, documents, or planning a visit.
  5. Reconfirm the location after court, medical transport, classification, contract placement, or transfer.

Why a jurisdiction can use more than one detention location

Local jail custody is normally handled by the responsible sheriff, county corrections department, detention center, regional jail, or another agency designated by the local government. State-prison and federal custody use separate systems. A jurisdiction may use an intake center, main jail, annex, work-release center, city jail, regional authority, juvenile facility, medical unit, courthouse holding area, or contracted beds. The public agency result or official information line is the best current source for where an adult is housed.

Mail, money, visitation, and phone services

Do not use a facility address or vendor from an old third-party page. Open the current official sheriff, corrections, jail, regional authority, or facility page and confirm the recipient format, inmate number, permitted items, vendor, visitation approval process, schedule, identification requirements, and communication rules. Transfers can invalidate previously correct instructions.

When the facility shown online changes

A location can change after court, classification, sentence, disciplinary action, medical care, protective placement, overcrowding, regional placement, contract housing, state transfer, federal hold, or release processing. A changed location does not by itself explain the person’s legal status.

State and federal alternatives

If the person has entered state custody, use the Oregon state inmate-search guide. The state agency is Oregon Department of Corrections and the published state tool is Oregon Offender Search. If federal custody is confirmed, use the federal BOP guide.

State-system limitation: County jail custody requires the county sheriff or local jail system County/local inclusion: No.

Frequently asked questions

How do I confirm the current jail for Multnomah County?
Use the verified local custody method or parent county guide, then confirm the facility shown by the responsible agency before mailing, visiting, paying, or traveling.
Does this page list every current facility?
No. It is a county-specific facility verification guide. Facility names, operators, addresses, contracts, and missions can change, so the current responsible agency controls.
Can a person be housed outside Multnomah County?
Yes. Regional-jail agreements, court transport, medical care, contract housing, state transfer, federal hold, and classification can place a person elsewhere.
Is the 2025 population a jail population?
No. The Census estimate describes the resident jurisdiction and is not an inmate count, rated capacity, or facility total.
What should I verify before mailing?
Confirm the current facility, recipient format, inmate or booking number, mailing address, permitted items, and any mail vendor on the official agency or facility page.
What should I verify before visiting?
Confirm the current housing location, approval process, schedule, identification rules, age limits, dress rules, and whether the visit is in person or remote.
When should I use the Oregon state locator?
Use it after a confirmed state commitment or transfer, or when the person is already known to be in state corrections custody.
When should I use the BOP locator?
Use it only after federal custody or BOP placement is confirmed.
Can an old directory name be wrong?
Yes. Facilities close, rename, change operators, change missions, or move services. Use the current official agency result.
Is All County Arrests the jail operator?
No. It is an independent official-source routing directory and does not operate facilities or store inmate records.
