FCI Lompoc I Overview
FCI Lompoc I is operated by the Federal Bureau of Prisons at the federal correctional complex in Lompoc. BOP facility data identifies it as a low security Federal Correctional Institution in Santa Barbara County, in the Western Region and the Central District of California. It houses male federal sentenced inmates. It is not a county jail and does not use Santa Barbara County's Who Is In Custody roster, county jail visitation schedule, TouchPay jail deposit page, or Sheriff's custody records process for routine federal inmate lookup.
The key distinction is custody authority. A person arrested locally may begin in a city police facility or county jail. A person sentenced to federal prison and designated to FCI Lompoc I is in BOP custody. The BOP locator covers federal inmates incarcerated from 1982 to present and can show name, register number, age, race, sex, release date, and location. BOP also warns that release dates may not always reflect First Step Act sentence review updates.
The manifest includes a direct screenshot of the official BOP FCI Lompoc I page. That source is the facility-specific reference for current BOP links, notices, visiting guidance, handbooks, commissary lists, and PREA material.

FCI Lompoc I Capacity and Population
BOP phyloc facility data dated May 28, 2026 listed 839 total inmates for FCI Lompoc I. The same BOP data identifies the institution as male and low security. That figure is a federal population report, not a Santa Barbara County jail population figure. County reports about Main Jail, Northern Branch Jail, local booking, and pretrial status do not describe the federal population at FCI Lompoc I.
The broader Lompoc complex has changed names and configurations in BOP materials, and local users may see references to FCC Lompoc, Lompoc I, Lompoc II, or older complex names. FCI Lompoc I refers here to the low security federal institution at 3600 Guard Road with BOP facility code LOF.
How to Look Up an Inmate at FCI Lompoc I
Use the BOP Inmate Locator for FCI Lompoc I. The BOP search allows a number search using BOP Register Number, DCDC Number, FBI Number, or INS Number, or a name search using last name, optional first and middle name, race, sex, and age. The Santa Barbara County Sheriff roster should not be used for a federal sentenced inmate unless the person is physically booked into county jail under a separate local custody event.
- Open the BOP Inmate Locator.
- Search by federal register number when known, or by exact last name with supporting name and demographic fields.
- Review the result for location, release date, register number, and custody status.
- Confirm the facility page for FCI Lompoc I before mailing, visiting, or relying on status details.
FCI Lompoc I Address and Contact
Contact and address information comes from BOP facility data. BOP also lists a facility email and fax in the research, but routine public inmate lookup should start with the locator and the official facility page. Do not call the Santa Barbara County Main Jail or Northern Branch Jail for BOP federal inmate records unless the question concerns a separate county booking.

Visiting Someone at FCI Lompoc I

Facility-specific visiting schedules and current operational notices should be checked directly on BOP before travel.

The county jail mail format with a CID number, the Sheriff's TouchPay Site ID, and county commissary guidance do not apply to FCI Lompoc I. Use BOP facility instructions and current BOP policy before sending mail, funds, or property. The research captured the inmate mail and parcel address from BOP JSON as the same Guard Road facility address.

Admission and Classification at FCI Lompoc I
Federal prison admission is different from street-arrest booking at a county jail. A person designated to FCI Lompoc I has moved into federal custody after federal proceedings, sentencing, designation, or transfer. BOP handles designation, intake, classification, housing, work, programming, medical review, and release calculations under federal rules. The county booking steps for bail, local court dates, and county classification do not control the person's federal sentence at FCI Lompoc I.
If a person was recently arrested in Santa Barbara County and has not been sentenced or transferred to BOP custody, start with the Sheriff's county roster. If the person is already a federal sentenced inmate, start with BOP. If a result shows released or not in BOP custody, the person may be outside BOP custody, in another system, on supervised release, or otherwise no longer located at a BOP facility.
About FCI Lompoc I
FCI Lompoc I is one of the federal institutions that make Lompoc a major custody location within Santa Barbara County, even though it is outside the county jail system. BOP records place the institution in the Central District of California and Western Region, serving male federal offenders at a low security level. Its presence can create lookup confusion because "Lompoc inmate" may refer to a federal prisoner, a city arrestee, or a county jail inmate transferred from north county.
No public federal mugshots are published through the BOP locator. Federal locator records focus on identity, register number, location, status, and release date. For court filings, use federal court systems. For local arrests, use the Sheriff or Superior Court systems. For immigration detention, use ICE ODLS if the person is in ICE custody.
Note: Use BOP sources for federal custody, and confirm visiting status directly with BOP before traveling.
