Federal Correctional Institution Herlong Overview
Federal Correctional Institution Herlong, commonly called FCI Herlong, is operated by the Federal Bureau of Prisons. The BOP Admission and Orientation handbook gives the facility address as Federal Correctional Institution, Herlong, 741-925 Herlong Access Road, A-25, Herlong, CA 96113, with phone (530) 827-8000. The BOP facility page identifies the judicial district as Eastern California.
FCI Herlong is physically in Lassen County, but that does not make it a Lassen County Sheriff's Office facility. The sheriff-operated jail and annex handle local custody for people arrested or sentenced on state crimes in Lassen County. High Desert State Prison is a CDCR state prison for sentenced California prisoners. FCI Herlong is the federal piece of the county's correctional map and should be researched through the BOP system.
The research describes FCI Herlong as a medium-security federal correctional institution with satellite prison camp or low facility references in BOP materials. It holds sentenced federal male offenders. Federal pretrial defendants may be housed under other arrangements before BOP designation, so the BOP locator is strongest for people in BOP custody from 1982 to the present, not every person recently arrested by a federal agency.
The official BOP FCI Herlong page provides facility resources for visiting, mail, money, commissary, PREA, and institutional documents.
The BOP facility page is the source to check for institutional notices and Herlong-specific resources before travel or mailing.
Federal Correctional Institution Herlong Capacity and Population
The research did not locate a public BOP capacity number for FCI Herlong on the BOP facility page. Because no sourced capacity figure was found, no bed-count statistic should be invented for this facility. For population interpretation, the safer distinction is agency-based: FCI Herlong's population is federal BOP custody, while the Lassen County jail population is sheriff custody and the High Desert State Prison population is CDCR custody.
A person can be incarcerated in Lassen County at FCI Herlong without appearing in a county jail roster or CDCR CIRIS. Use BOP records for federal prison location and release information, and use county or state systems only when the person's custody level points to those agencies.
How to Look Up an Inmate at Federal Correctional Institution Herlong
Use the BOP Inmate Locator for people in federal Bureau of Prisons custody. The locator supports searches by BOP register number, DCDC number, FBI number, INS number, or name. BOP sample results show fields such as name, register number, age, race, sex, release date, and location. The result location is the field that tells whether the person is at FCI Herlong.
- Open the BOP Inmate Locator and choose number search or name search.
- Use a register number when available, or enter the person's legal first and last name.
- Review the result fields, especially register number, release date, and location.
- Confirm that the location is Federal Correctional Institution Herlong before using Herlong visiting, mail, or money instructions.
BOP cautions that release dates may change due to First Step Act sentence recalculations. A result marked Released or Not in BOP Custody does not prove the person is not in another system, such as county jail, CDCR, ICE, supervised release, or another law-enforcement custody path.
The BOP Inmate Locator is the correct search source for federal prisoners at Herlong.
The locator's register number and location fields are practical because BOP mail and facility confirmation depend on the same identifying information.
Federal Correctional Institution Herlong Address and Contact
Use the BOP facility contact for Herlong-specific questions and use the BOP locator for federal custody search. The Lassen County jail phone is not the right lookup source for BOP prisoners, and CDCR CIRIS is not the right lookup source for federal prisoners. If a federal defendant is not yet in BOP custody, federal court or U.S. Marshals routing may be more appropriate than the BOP facility page.

Visiting Someone at Federal Correctional Institution Herlong
FCI Herlong visiting is governed by BOP rules and Herlong's institutional visiting regulations. The A&O handbook lists ordinary visiting on Saturday, Sunday, and federal holidays from 8:00 a.m. to 3:00 p.m. It also lists Friday SHU visiting only from 8:00 a.m. to 3:00 p.m. BOP regulations caution that no visitors are permitted on grounds before 8:00 a.m., and no visitors are processed after 2:00 p.m.
Visitors age 16 and older need current valid photo identification. The research notes a visitor list limit of 20 and an A&O handbook limit of five adults at one time, excluding children under 16. Herlong visiting can be restricted or cancelled by the Warden for safety, security, severe weather, or other operational reasons, so the facility should be called before departure.
| Day | Hours | Type |
|---|---|---|
| Friday | 8:00 a.m.-3:00 p.m. | SHU visiting only |
| Saturday | 8:00 a.m.-3:00 p.m. | Ordinary visiting |
| Sunday | 8:00 a.m.-3:00 p.m. | Ordinary visiting |
| Federal holidays | 8:00 a.m.-3:00 p.m. | Holiday visiting |
| Processing cutoff | No processing after 2:00 p.m. | Visitor entry rule |
Mail, Phone, and Money at Federal Correctional Institution Herlong
BOP mail and money rules are federal rules. Mail to a federal inmate must include the inmate's name and register number, which is why the BOP locator result matters before writing. The BOP facility page links Herlong resources such as the commissary list, Admission and Orientation handbook, legal activities materials, and PREA report.
Do not send funds to the institution address. BOP says funds sent through the mail must go to the national processing center in Des Moines, Iowa, regardless of the institution where the person is housed. The research did not locate a Herlong-specific fee table for deposits, so deposit costs should be checked through current BOP money guidance before sending funds.
| Service | Provider / Detail |
|---|---|
| Mail Address | Use inmate name and register number with BOP facility mail format for FCI Herlong. |
| Phone / Video | Use BOP institution rules and current facility guidance. |
| Money Deposit | Do not send money to FCI Herlong; mailed funds go to the BOP Des Moines processing center. |
Federal Designation and Intake at Federal Correctional Institution Herlong
FCI Herlong does not book new county arrests like a sheriff's jail. A person arrested by a local or state agency in Lassen County generally starts in the local criminal process. A person convicted in federal court may later enter BOP custody and receive a federal facility designation. Once BOP custody applies, the BOP register number becomes the key identifier for lookup, mail, and many institution processes.
The county jail page lists FBI and Herlong Security among agencies that may bring people to the county jail, but that does not mean FCI Herlong is the county booking facility or that the county jail has a public federal roster. Federal pretrial detainees may move through court, U.S. Marshals, local detention contracts, or BOP custody depending on the stage of the case. For a sentenced BOP prisoner, the BOP locator is the main public search path.
About Federal Correctional Institution Herlong
FCI Herlong is a major part of Lassen County's unusual correctional footprint. Research notes place it about 35 miles south of Susanville on US 395, near Herlong rather than on the Susanville Sheriff Cady Lane government complex. That location matters for visitors because the BOP handbook states no public transportation is currently available from Reno or Susanville to Herlong.
The facility also adds a federal layer to local search questions. A person can be "in Lassen County" geographically while being held by the Federal Bureau of Prisons, not by Lassen County and not by CDCR. The right lookup source depends on the custody system: sheriff records and the jail phone for local detention, CDCR CIRIS for California state prison, BOP for federal prison, and ICE ODLS only for immigration detention. BOP and ICE public locators are not mugshot galleries and should not be described as sources for federal booking photos.
FCI Herlong's institutional resources include visiting regulations, mail guidance, money guidance, commissary information, Admission and Orientation materials, legal activities material, and PREA resources. Those documents are more useful for a person already confirmed at Herlong than a county court portal or a local booking contact.
Note: Confirm the BOP location, visiting status, and travel conditions with FCI Herlong before leaving for the facility.
