Western Regional Office at a glance
The Western Regional Office is the Bureau of Prisons’ regional headquarters for the western states, and every institution it runs is in Arizona, California, Hawaii, Oregon or Washington. From 7338 Shoreline Drive in Stockton, California, it oversees 17 federal institutions holding 16,870 people as of September 2026, and it answers to the Central Office in Washington, D.C. Every BP-10 from those prisons is decided here.

What does the Western Regional Office do?
Nobody is held at Stockton. The Bureau’s Offices page describes the job: “Six regional offices provide oversight and technical assistance to the facilities located in their respective region of the country. In addition to providing operational oversight, regional office staff conduct workshops, conferences, and specialized training programs for their region; assist state and local criminal justice agencies; and contract to provide offender placement in residential reentry centers.”
Its rank is set by regulation. Under 28 C.F.R. § 503.1, “The Bureau of Prisons consists of a Central Office, located at 320 First Street, NW., Washington, DC 20534, a Staff Training Center, and six Regional Offices (Northeast, Mid-Atlantic, Southeast, North Central, South Central, and Western).” Above it is the Central Office; its five sister offices are listed on our regional offices page.
For a family the consequence is narrow: a warden’s answer to a grievance is appealed here. The Bureau’s page for the office points relatives elsewhere first: family members, support persons and advocates “with questions or concerns about a specific incarcerated person in a facility within the Federal Bureau of Prisons Western Region may contact a Support and Advocacy Program Coordinator”. Its Leadership line is filled in by a script and was empty in the copy we read on September 18, 2026, so no regional director is named here.
Which federal prisons does the Western Regional Office oversee?
Seventeen institutions in five of the eleven states the Bureau assigns to this region: Arizona, California, Hawaii, Oregon and Washington. The population report of September 10, 2026 puts 16,870 people in them, 15,361 at the institutions themselves and 1,509 at their camps.
| Institution | Type and security | Population | Camp or satellite |
|---|---|---|---|
| Arizona | |||
| USP Tucson | U.S. Penitentiary · High | 972 | Camp: 120 |
| FCI Phoenix | Federal Correctional Institution · Medium | 873 | Camp: 198 |
| FCI Tucson | Federal Correctional Institution · Medium | 475 | — |
| FCI Safford | Federal Correctional Institution · Low | 660 | — |
| California | |||
| USP Atwater | U.S. Penitentiary · High | 1,143 | Camp: 144 |
| USP Victorville | U.S. Penitentiary · High | 1,001 | — |
| FCI Herlong | Federal Correctional Institution · Medium | 554 | Camp: 82 |
| FCI Mendota | Federal Correctional Institution · Medium | 648 | Camp: 121 |
| FCI Victorville Medium I | Federal Correctional Institution · Medium | 1,369 | Camp: 226 |
| FCI Victorville Medium II | Federal Correctional Institution · Medium | 1,327 | — |
| FCI Lompoc I | Federal Correctional Institution · Low | 885 | — |
| FCI Lompoc II | Federal Correctional Institution · Low | 1,895 | Camp: 119 · Camp: 220 |
| MCC San Diego | Metropolitan Correctional Center · Administrative | 565 | — |
| MDC Los Angeles | Metropolitan Detention Center · Administrative | 897 | — |
| Hawaii | |||
| FDC Honolulu | Federal Detention Center · Administrative | 210 | — |
| Oregon | |||
| FCI Sheridan | Federal Correctional Institution · Medium | 1,214 | Camp: 279 |
| Washington | |||
| FDC SeaTac | Federal Detention Center · Administrative | 673 | — |
| Total | 17 institutions in 5 states | 15,361 | 1,509 |
California holds ten of the seventeen, and FCI Lompoc II is the largest single institution in the region at 2,234 people once its two camps are counted. Three sites are complexes on the roster, so address mail to the institution, not the complex: FCC Lompoc takes in FCI Lompoc I and FCI Lompoc II, FCC Tucson the penitentiary and FCI Tucson, and FCC Victorville the penitentiary and both medium-security FCIs. Four entries carry the Administrative security level on the roster: MDC Los Angeles, MCC San Diego, FDC SeaTac and FDC Honolulu.
Six of the eleven states on the Bureau’s list have no Bureau institution at all: Alaska, Idaho, Montana, Nevada, Utah and Wyoming. The Offices page, read on September 18, 2026, prints the region as Alaska, Arizona, California, Idaho, Hawaii, Montana, Nevada, Oregon, Utah, Washington and Wyoming, in that order. Someone sentenced in one of those six states is held wherever the Bureau designates.
Which RRM offices are in the Western Region?
Four, each running the halfway-house contracts and home-confinement caseload for the districts its own page prints (read September 17, 2026). RRM Long Beach, which works from San Pedro, prints Central and Southern California. RRM Phoenix prints Arizona and Southern Nevada. RRM Sacramento prints Eastern and Northern California, Guam, Hawaii and Northern Nevada. RRM Seattle, which gives the FDC SeaTac street address, prints Alaska, Eastern and Western Washington, Idaho and Oregon. All 22 offices are tabulated on our index of RRM offices.
Nevada is divided in a way the courts are not. 28 U.S.C. § 108 provides that “Nevada constitutes one judicial district”, yet the Bureau prints “Northern Nevada” under Sacramento and “Southern Nevada” under Phoenix. Which office holds a Nevada release plan is a question for the unit team.
Three states in the region appear on no reentry office’s page. Montana (28 U.S.C. § 106), Utah (§ 125) and Wyoming (§ 131) are each a single judicial district, and none of the 22 office pages printed any of them when we read them on September 17, 2026. That is a gap in what the Bureau publishes, not proof that nobody handles them, and this page assigns them to no office. See our pages on halfway houses and home confinement.
How do I appeal to the Western Regional Director (BP-10)?
A warden’s answer to a BP-9 is appealed to this office on a BP-10. Program Statement 1330.18 (Jan. 6, 2014), at pp. 6–7, allows an appeal “on the appropriate form (BP-10) to the appropriate Regional Director within 20 calendar days of the date the Warden signed the response.” Begin with our guide to filing a BP-9 and the Administrative Remedy Program policy page.
The packet matters as much as the date. PS 1330.18 at p. 7 requires the appeal to be “accompanied by one complete copy or duplicate original of the institution Request and response”, and “The inmate shall provide two additional copies of any continuation page and exhibits with the regional Appeal”. Nothing new can be added at this stage: “An inmate may not raise in an Appeal issues not raised in the lower level filings” (at p. 7).
The processing office is the one for the institution where the person is confined at mailing, “regardless of the institution that responded to the institution filing” (PS 1330.18 at p. 7). Someone moved from FCI Sheridan to a prison in another region before mailing sends the BP-10 there, not to Stockton.
The 20 days are counted at the receiving end: the deadlines “specify the date of the Appeal’s receipt in the regional office or the Central Office” (PS 1330.18 at p. 7). A late appeal can be accepted for the reasons listed in 28 C.F.R. § 542.14(b), such as a long stretch in transit away from one’s papers.
On the response schedule at PS 1330.18 at p. 9, the appeal is answered “by the Regional Director within 30 calendar days” of being logged as received. The extension schedule two sentences later lets the region extend once, by 30 days, in writing. Silence past both may be treated as a denial at this level.
Two filings can start here. A request whose disclosure at the prison would endanger the person may go “directly to the appropriate Regional Director”, marked “Sensitive” with a written reason (PS 1330.18 at p. 6). And an appeal from a Discipline Hearing Officer is filed with the region too: “DHO appeals shall be submitted initially to the Regional Director for the region where the inmate is currently located” (PS 1330.18 at p. 6).
Next comes the BP-11 to the General Counsel. On litigation, the statement says only: “In many cases, courts require a proper Appeal to the General Counsel before an inmate may pursue the complaint in court” (PS 1330.18 at p. 7). See our page on the § 2241 petition.
How do I contact the Western Regional Office?
By telephone at 209-956-9700 or by fax at 209-956-9793. The Bureau lists WXR-ExecAssistant-S@bop.gov as the office’s mailbox. Correspondence for staff goes to the named person at 7338 Shoreline Drive, Stockton, California 95219.
The Bureau’s physical, staff-mail and shipping records for Stockton all read “7338 SHORELINE DRIVE”, with no suite number; freight adds an “ATTN: WAREHOUSE” line.
This office holds nobody, so letters and money for a person never go here. Both go to the institution, under that institution’s rules; see our guides to writing to someone in federal prison and sending money. Stockton is the address for a BP-10, a sensitive request or a letter to a member of staff.
Which western prisons have left the Bureau’s roster?
Three California prisons that older directories still list were missing from the Bureau’s roster when we queried it on September 18, 2026.
The former Taft Correctional Institution is the only facility in this region named in the Bureau’s July 1, 2026 closure release, and the only institution on that list to have left the roster since; the other five named there were still on it on September 18, 2026. The release said the Bureau “will close” Taft FCI and explained: “Minimal staff will be affected at La Tuna FSL and Taft FCI, as both facilities are currently non-operational; however, each facility will be permanently closed.”
The former FCI Dublin, a women’s prison in Alameda County, and the former FCI Terminal Island at San Pedro are gone from the roster as well. Neither is named in the July 2026 release.
One rule covers all three. A BP-10 about something that happened at a closed prison goes to the region for the institution where the person is held now, which may not be this one.
Frequently Asked Questions
How many federal prisons are in the Western Region?
Seventeen, in Arizona, California, Hawaii, Oregon and Washington. The Bureau’s population report of September 10, 2026 counted 16,870 people in them, from the penitentiaries at Atwater, Tucson and Victorville to the detention centers at Honolulu and SeaTac. California has ten of them; the six other western states the Bureau assigns to this region have none.
Where do I send a BP-10 from a prison in Arizona?
To the Western Regional Office, 7338 Shoreline Drive, Stockton, California 95219, provided the person is still held in Arizona when the appeal is mailed. All four Arizona institutions, at Phoenix, Safford and Tucson, belong to this region. Program Statement 1330.18 at p. 7 ties the appeal to where the person is confined at mailing.
How long does the Western Regional Director have to decide a BP-10?
Thirty calendar days from the date the appeal is logged as received, under the response schedule in Program Statement 1330.18 at p. 9. The same page allows the region one extension of 30 days, given in writing. If no answer arrives within the time allowed, including any extension, the person may treat the silence as a denial.
Is Nevada in the Western Region?
Yes, on the Bureau’s Offices page, though it has no Bureau institution. For reentry the Bureau divides the state, printing Northern Nevada under RRM Sacramento and Southern Nevada under RRM Phoenix, even though federal law makes Nevada a single judicial district. Ask the unit team which office holds a Nevada release plan.
Which reentry offices serve the western states?
Four: RRM Long Beach, RRM Phoenix, RRM Sacramento and RRM Seattle. Between them they print districts in California, Arizona, Nevada, Hawaii, Guam, Washington, Oregon, Idaho and Alaska. Montana, Utah and Wyoming appear on none of the Bureau’s office pages, so for those release districts only the unit team can say where the referral goes.
Does the Western Regional Office arrange halfway-house placement?
Only at one remove. The Bureau says its regional offices contract to provide offender placement in residential reentry centers, but a referral begins with the unit team at the institution, and the contracts are run by the reentry office for the release district. Questions about a particular placement belong with the unit team first.
Where we can help
We work on remedy appeals, transfers among the western prisons, and compassionate release requests a warden has refused.
Discuss a Discipline or Custody Issue. You leave with an assessment of whether the Bureau followed its own policy, and what to file if it did not. A BP-9 is due 20 calendar days after the event it complains of. 28 C.F.R. § 542.14(a).
Call 843-620-1100 or contact us to arrange a paid one-hour consultation about a specific situation. Calls are answered 24 hours a day. Related: our compassionate release and prison consulting pages.
