USP Allenwood Federal Overview
USP Allenwood is a high-security United States Penitentiary operated by the Federal Bureau of Prisons. BOP endpoint data lists the institution in the Northeast Region, Middle Pennsylvania judicial district, and Union County, with male offenders and high security level. The public address is RT 15, 2 Miles N of Allenwood, Allenwood, PA 17810. The institution is part of the Allenwood complex with FCI Allenwood Low and FCI Allenwood Medium.
The federal identity of USP Allenwood matters for every lookup task. It is not a local jail for people newly booked after a Union County arrest, and it should not be described with county bail, county court commitment, or county mugshot assumptions. A person in USP Allenwood is searched through BOP, and a person in local Union County custody is searched through the jail phone, county records process, UJS, VINE, and other local or state channels.
USP Allenwood also differs from the two FCI Allenwood facilities in security level and mail routing. The shared Allenwood name should not be used as a shortcut. Check the exact BOP location before sending mail, comparing population numbers, or asking about visits.
The official BOP USP Allenwood page is the facility source for public policy links, contact details, visiting regulations, commissary information, legal activities, and PREA material.
The facility profile supports mail, visit, and policy checks, but federal inmate location searches still run through the BOP locator.
USP Allenwood Inmate Population
BOP reported 373 inmates at USP Allenwood on June 18, 2026. The public BOP profile reviewed for this research did not publish a rated capacity figure. The 373 count is a federal prison population figure, not a Union County Jail current population and not a county arrest count. Union County's inmate-population picture includes a small local jail plus large federal institutions, so each number needs the correct label.
| Measure | Figure | Source Date |
|---|---|---|
| Population | 373 | BOP public endpoint, June 18, 2026 |
| Rated capacity | Not published in public profile reviewed | BOP facility materials |
| Custody type | Male federal sentenced inmates | BOP endpoint and facility map |
USP Allenwood Custody Lookup
USP Allenwood custody lookup uses the BOP Inmate Locator. The locator's number search accepts BOP Register Number, DCDC Number, FBI Number, or INS Number. The name search uses first name, middle name, last name, race, age, and sex fields. Public results show name, register number, age, race, sex, release date, and location.
The public locator is not designed to provide every record a family may want. It gives a federal location and core identifying fields, while detailed program, disciplinary, medical, or security information remains outside the public search result. For nonpublic federal agency records, BOP FOIA is the correct federal route.
- Search by register number if the federal number is known.
- Search by name and demographic filters when a number is not known.
- Check the result location and confirm it says USP Allenwood.
- Use the register number in mail, phone questions, and any facility communication.
- Recheck the locator if timing matters because BOP release dates may change after First Step Act recalculation.
The BOP locator is a federal search tool and should not be treated as a Union County jail roster. If the search is really about a recent local arrest, use the county jail and court record channels instead. USP Allenwood may be physically in Union County, but BOP custody records are federal.
USP Allenwood Contact
BOP provides a facility phone, fax, email address, inmate mail address, staff mail address, and physical shipping address. Mail to an inmate must use the committed name and register number. Staff mail uses a different post office box, and the physical address should not be substituted for inmate funds because BOP money rules use separate channels.

USP Allenwood Visiting
USP Allenwood visiting follows BOP rules and the facility-specific visiting regulations linked from the BOP page. Visitor approval, identification, conduct, dress, and security screening are federal requirements. The Warden can restrict or cancel visits for safety, security, severe weather, or institutional incidents. Because USP Allenwood is high security, confirming current visit status before travel is especially important.
| Visit Topic | USP Allenwood Detail | What to Do |
|---|---|---|
| Visitor approval | BOP process applies | Confirm the visitor is on the approved list |
| Schedule | Facility visiting regulations linked by BOP | Check current day, time, and housing restrictions |

USP Allenwood Mail and Money
Mail and money rules for USP Allenwood follow BOP communications guidance. Inmate funds should not be sent to the facility address. BOP directs mailed funds to the Des Moines processing center and allows approved electronic channels such as Western Union Quick Collect or MoneyGram. BOP's communications page says some electronic funds are processed seven days per week, with timing tied to Eastern time submission windows.
USP Allenwood's inmate mail box is P.O. Box 3000 in White Deer. Staff mail uses P.O. Box 3500. Those boxes are different from FCI Allenwood Low and FCI Allenwood Medium, so the exact facility name and register number should appear on correspondence.

| Staff mail | P.O. Box 3500, White Deer, PA 17887 |

USP Allenwood Records
Public BOP locator results are limited. They identify the person, federal register number, basic demographics, release date, and location, but they generally do not publish mugshots. For federal records beyond the public locator and facility page, use BOP FOIA. For Union County court charges, use UJS Case Search. For current local custody or booking records, use Union County Jail and the county Right-To-Know process rather than USP Allenwood.

About USP Allenwood
USP Allenwood rounds out the Allenwood federal complex in Union County. It should be grouped with FCI Allenwood Low and FCI Allenwood Medium in facility lists, but it remains a separate high-security institution with its own population figure, phone number, fax number, and inmate mail box. People searching for an Allenwood inmate should verify the exact BOP location because the low, medium, and penitentiary institutions do not share the same mail address.
The federal prison footprint in Union County can confuse local custody searches. A person can be incarcerated inside Union County without being a Union County Jail inmate, and a person arrested in Union County may never appear in the BOP locator unless federal custody applies. For jail and court distinctions across the county, the Union County inmate population overview separates local jail custody from BOP institutions.
Note: Confirm the exact USP Allenwood location and mail address before sending anything to a federal inmate.
