What FCI Danbury Is
Federal Correctional Institution Danbury is run by the Federal Bureau of Prisons, the agency known as the BOP. It is a federal institution, not a city lockup and not a Connecticut state prison. The complex sits in Danbury, but its custody system is separate from both the Danbury Police Department and the Connecticut Department of Correction. People held here were sentenced in a federal case or are in federal custody. A person picked up by Danbury police does not land here just because the arrest happened in the city.
The BOP admission and orientation handbook describes the site as three facilities on one complex. The main one is the FCI, a low security institution for men. The FSL is a Federal Satellite Low for women. The SCP is a Satellite Prison Camp for women. A satellite camp is a small, lower security unit attached to a larger prison. So the complex holds both male and female inmates across these three parts, each with its own role and security tier.
Note: A federal sentence, a federal court case, or a U.S. Marshals or BOP hold is what places someone at FCI Danbury, not a local Danbury arrest.
How to Look Up a Federal Inmate at FCI Danbury
To find someone held at FCI Danbury, use the federal BOP inmate locator. This is the only official tool for federal custody. The Connecticut Department of Correction search and the Danbury court tools will not show a federal inmate. You can search two ways. You can search by a known number, or you can search by name. Each path uses its own set of fields, and the locator returns the same kind of result card either way.
The federal page covers all BOP custody, so a match could sit at any federal site, not just Danbury. Once you open the result, the location field tells you whether the person is at FCI Danbury or another institution. The steps below walk through a basic name or number search on the locator.
You can also reach the institution through its official BOP FCI Danbury page. That page links to detailed BOP facility information.
That facility page is the starting point for visiting resources, mail and money rules, and a link into the federal inmate locator itself.
- Open the BOP inmate locator at bop.gov/inmateloc and pick the Find By Number tab or the Find By Name tab.
- For a number search, choose the type of number and type it in. For a name search, enter the first and last name; the middle name, race, age, and sex are optional.
- Click Search and review the result card to confirm the location field reads FCI Danbury.
- Open the related links on the result for the institution, mail and package rules, sending money, and visiting.
FCI Danbury Locator Search Fields
The BOP locator gives you two ways to find a federal inmate. The number search needs a single identifier. The name search needs a first and last name and lets you narrow results with optional details. A register number is the unique BOP identifier for an inmate, written in a #####-### format. The table below lists the fields the federal locator uses for an FCI Danbury inmate search.
| Field | Type | Required | Notes |
|---|---|---|---|
| Type of Number | Dropdown | Yes for number search | BOP Register Number, DCDC Number, FBI Number, or INS Number. |
| Number | Text | Yes for number search | BOP register number in the #####-### format. |
| First | Text | Yes for name search | First name of the inmate. |
| Middle | Text | No | Middle name or initial. |
| Last | Text | Yes for name search | Last name of the inmate. |
| Race | Dropdown | No | Blank, American Indian, Asian, Black, or White. |
| Age | Text | No | Numeric age. |
| Sex | Dropdown | No | Blank, Male, or Female. |
The DCDC, FBI, and INS numbers are alternate identifiers some inmates carry from prior systems. Most people will search by name or by BOP register number. The locator also offers Search and Clear Form controls to run or reset the query.
What a BOP Locator Result Shows
A match on the federal locator returns a compact card, not a full case file. It confirms identity and basic custody facts. It does not show a booking photo. There are no public federal mugshots in the locator; it shows identity and custody fields only. That is a key difference from many county rosters. The table below lists the fields a result card shows for an FCI Danbury inmate.
| Field | What It Shows |
|---|---|
| Name | Federal inmate name. |
| Register Number | BOP register number in the #####-### format. |
| Age | Current age. |
| Race | Race category. |
| Sex | Male or female. |
| Release Date | Federal release date or release status. |
| Location | The BOP facility, such as FCI Danbury, or a released status. |
| Related Links | Institution page, call or email, mail and package, send money, visit, and voice a concern. |
The related links carry most of the practical help. They route you to the institution page, to mail and package rules, to the money process, and to visiting information for that site.
Note: The locator covers people currently in federal custody, so a released person or someone never in BOP custody will not appear in a search result.
FCI Danbury Address and Contact
The institution lists a mailing address and a main phone line through the BOP contact directory. Use the phone line for general questions about the institution. Do not use the street address to send money, since federal funds route through a separate processing center described further below. The card here gives the core contact details for the Danbury complex.
Federal Correctional Institution Danbury
33 1/2 Pembroke Station, Route 37

Directions to FCI Danbury
The institution is three miles north of Danbury on Route 37. Interstate 84 is the main east and west route to the area. The handbook gives a simple split based on your direction of travel, since the right exit depends on which way you approach the city. Confirm the route in a map app before you travel, and remember this is a federal site separate from the downtown police headquarters and the courthouse.
- Traveling east on I-84, take Exit 5 and proceed onto Route 37 North to the institution.
- Traveling west on I-84, take Exit 6, turn right on Route 37 North, and proceed to the institution.
- The complex sits about three miles north of the city center on Route 37.
Mail and Money at FCI Danbury
Federal mail and money rules are strict, and they differ from county jail practice. Do not send money to the facility address. All funds sent through the mail must go to the BOP processing center in Des Moines, Iowa, not to the Danbury complex. Money that reaches the wrong address can be delayed or returned. The BOP page is the authority on the current process, so confirm the exact center address before you mail anything.
Mail for an inmate uses a set format. You write the inmate name and register number, then the facility title, then the address. The Danbury complex has separate mailing labels for the FCI, the Satellite Camp, and the Federal Satellite Low, so use the label that matches where the person is held. The register number ties the mail to the right person, which is why the locator step matters first. The table below sorts the basic services.
| Service | Detail |
|---|---|
| Money by Mail | All mailed funds go to the BOP processing center in Des Moines, Iowa, not to the facility. |
| Inmate Mail | Use inmate name and register number, the facility title, and the address. |
| Facility Labels | Separate labels for the FCI, the Satellite Camp, and the Federal Satellite Low. |
| Visiting Resources | Linked from the official BOP FCI Danbury facility page. |
Visiting resources are linked from the BOP facility page rather than set by a local schedule. Check that page for current visiting days, approval steps, and rules before you plan a trip, since federal visiting is approved and arranged through the institution.
Intake and Programs at FCI Danbury
The BOP handbook lays out a clear intake path for new arrivals. Unit Management staff give a social screening, and Health Services staff give a medical and mental health screening. Each inmate gets the institution rules, a statement of rights and responsibilities, and PREA information about preventing sexual abuse. Within 28 days, the inmate takes part in Admission and Orientation, often called A&O, which is the formal introduction to the institution. Each person is assigned to a housing unit served by a Unit Team. A unit team is the group of staff who manage an inmate's case and daily needs in that unit.
Programs at the complex span school, work, health, and faith. The handbook lists education and recreation services, a GED program, and ESL for English learners. Health Services covers routine medical and dental care, with a sick call for new problems and staff referral for urgent needs. Other listed activities include a religious diet program, food service, legal activities, and a problem resolution process for grievances. These programs run inside the institution and are managed by federal staff, not by any local Danbury agency.
Federal vs State Custody in Danbury
Readers often assume the prison in Danbury is where local arrestees go. It is not. Four different systems can hold a person tied to the Danbury area, and each one has its own search tool. A person arrested by Danbury police is processed locally, then moves through the Danbury GA 3 court and possibly into Connecticut Department of Correction custody. Only a federal case, with a federal court, the U.S. Marshals, and a BOP designation, lands someone at FCI Danbury. The table sorts who holds whom and where to search.
| System | Who It Holds | Where to Search |
|---|---|---|
| Danbury Police | People just arrested, held briefly for processing. | Police records and FOIA at the Danbury Police Department Headquarters. |
| CT DOC | Connecticut pretrial and sentenced state inmates. | The CT DOC inmate search. |
| Federal BOP | Sentenced federal inmates at FCI Danbury and other sites. | The BOP inmate locator. |
| ICE | Immigration detainees in ICE or long CBP custody. | The ICE detainee locator. |
Important: BOP custody is federal only. People held on city or state arrests will not appear in the federal inmate locator, so use the Danbury police, CT DOC, or court tools for those cases instead.
Immigration custody is a different system again. ICE detainees are searched through the ICE Online Detainee Locator, which covers people in current ICE custody or in CBP custody for more than 48 hours. It does not search minors under 18. For help, the ICE detainee information page lists the Detention Reporting and Information line at 1-888-351-4024. No ICE detention facility exists in Danbury, so an immigration hold tied to a local case would be held elsewhere. For Connecticut state custody by contrast, the state inmate search is the right path, and the local custody picture is covered on the jail inmate records page.
The federal locator shown here is the single official tool for confirming whether a person is held at FCI Danbury or another Bureau of Prisons site.
