FCI Allenwood Low Overview
FCI Allenwood Low is operated by the Federal Bureau of Prisons. BOP endpoint data lists it in the Northeast Region, Middle Pennsylvania judicial district, and Union County, with low security level and male offenders. It is part of the Allenwood complex through complex code ALX, along with FCI Allenwood Medium and USP Allenwood. Its public address is RT 15, 2 Miles N of Allenwood, Allenwood, PA 17810.
The facility should be presented as a federal prison, not as a county jail. A person arrested in Union County normally starts in local custody and court channels, while a person at FCI Allenwood Low is in sentenced federal custody. That difference controls the lookup system, the mail format, the money rules, and what type of public record can be expected.
Because Allenwood has more than one BOP institution, the exact facility name matters. FCI Allenwood Low, FCI Allenwood Medium, and USP Allenwood are related by complex geography, but they use different security levels, populations, phone numbers, and inmate mail boxes. A locator result should be checked for the full facility name before anyone sends mail or calls the wrong institution.
The official BOP FCI Allenwood Low page publishes the federal facility profile and links to visiting regulations, handbooks, commissary material, legal activities, and PREA documents.
The BOP page is the source for facility policy links, but the actual inmate search runs through the national BOP locator.
FCI Allenwood Low Population
BOP reported 1,014 inmates at FCI Allenwood Low on June 25, 2026. The public profile reviewed for this research did not publish a rated capacity figure. The count is a federal population figure, not Union County Jail average daily population and not a measure of local arrests. Union County has a small county jail and a large federal prison presence, so searchers should keep those numbers in separate categories.
| Measure | Figure | Source Date |
|---|---|---|
| Population | 1,014 | BOP public endpoint, June 25, 2026 |
| Rated capacity | Not published in public profile reviewed | BOP facility materials |
| Population held | Male federal sentenced inmates | BOP endpoint and facility map |
FCI Allenwood Low Lookup
The correct lookup channel is the BOP Inmate Locator. It covers federal inmates from 1982 to the present and lets users search by BOP Register Number, DCDC Number, FBI Number, INS Number, or by name. Union County Jail does not track federal sentenced custody, and county court dockets are not a substitute for the BOP location field.
BOP results can also prevent a common error. A person with a federal release date, BOP register number, and FCI Allenwood Low location is not being listed as a new Union County booking. If the same person has older Union County court records, those dockets may still exist in UJS, but the custody status for the federal sentence comes from BOP.
- Search by BOP register number when it is known, using the federal number format shown by BOP.
- Search by name when no number is available, adding race, age, and sex filters if needed.
- Review the result for name, register number, age, race, sex, release date, and location.
- Confirm the location says FCI Allenwood Low before sending mail, planning a visit, or using the facility phone number.
- If the result says Released or Not in BOP Custody, check other systems because the person may still be in court, jail, parole, or supervised release.
FCI Allenwood Low Contact
BOP lists a physical location, inmate mail address, staff mail address, and shipping address for FCI Allenwood Low. Mail to an inmate should include the full committed name and register number. Staff mail uses a different post office box, and shipping uses the Route 15 physical address. For visit status, facility access, or a policy question, use the facility phone or BOP facility page.
The staff mail address should not be used as an inmate mail substitute. Inmate mail goes to P.O. Box 1000 in White Deer, while staff mail goes to P.O. Box 1500. That distinction is one of the easiest ways to avoid delay, especially when families are comparing multiple Allenwood addresses from search results.

FCI Allenwood Low Visiting
The BOP facility page provides links for visiting overview and facility visiting regulations. Research captured that the endpoint visitDays array did not show public visiting days at the time of capture, so visitors should use the posted regulations and call the facility before travel. BOP visiting can change because of unit status, security limits, severe weather, holidays, or Warden restrictions.
| Visit Topic | Published Detail | Action |
|---|---|---|
| Public visiting days | Not shown in endpoint visitDays array at capture | Check BOP regulations and call facility |
| Visitor status | BOP approval process applies | Confirm approval before travel |
| Changes | Warden or security restrictions may apply | Verify current access |
FCI Allenwood Low Mail and Money
Federal inmate money should not be sent to the facility address. BOP communications guidance routes funds through the Des Moines processing center for mailed funds or through approved electronic channels. The facility page also links a commissary list and handbook material. Those sources should be checked for current item limits, spending rules, and account restrictions.
| Service | Provider or Detail |
|---|---|
| Inmate mail | FCI Allenwood Low, P.O. Box 1000, White Deer, PA 17887 |
| Staff mail | P.O. Box 1500, White Deer, PA 17887 |
| Money | Use BOP-approved channels, not the facility address |
| Commissary | BOP facility page links commissary list |
FCI Allenwood Low Records
FCI Allenwood Low records are federal records. BOP FOIA is the federal records route when a nonpublic federal record is needed and ordinary facility channels do not provide it. BOP public locator records generally do not publish mugshots. If a search concerns a Union County arrest, local charges, or bail, start with Union County Jail and UJS instead of the federal facility. The Union County inmate population page separates the county jail count from federal prison populations located in the county.

- Federal Custody

About FCI Allenwood Low
FCI Allenwood Low is one part of Union County's unusually large federal prison footprint. It is located near the Allenwood and White Deer area along Route 15 and is tied to the Allenwood complex. For families, the most practical difference from Union County Jail is that all routine inmate search, mail, visiting, funds, and public facility documents use BOP systems. County roster and local booking-photo expectations should not be imported into federal prison records.
BOP materials also help separate program and policy documents from public custody records. Handbooks, legal activities policies, commissary lists, and PREA documents describe facility operations, but they do not replace the BOP locator for confirming that a named person is currently housed at FCI Allenwood Low.
Note: Confirm the BOP location and the current visiting schedule before sending mail or traveling to FCI Allenwood Low.
