How to Search for a Federal Inmate in the Bureau of Prisons

The Bureau of Prisons Inmate Locator includes inmates that are not only in custody, but who have been in custody and have been released (or who died in custody) since 1982. 

For inmates in custody prior to 1982, visit the National Archives Records Administration and provide the following information:

  • Inmate name (including middle name/initial),
  • Inmate's date of birth or approximate age at time of incarceration,
  • Inmate's race, and
  • Inmate's approximate dates in prison.

Federal Inmate Search

Searching by Name

  • You must enter the exact spelling of the inmate's FIRST and LAST name.
  • If the inmate's name is a common name, you may want to type in their age (as of today) and race to limit the number of results.
  • If you enter only an inmate's LAST name and an initial for the first name, you will NOT get a result.

Searching by Name Results


Searching by Number

  • If you know the inmate's BOP Register Number (ex: 12345-678), you can enter that to get an exact result.
  • You can also enter an inmate's DCDC Number, FBI Number or INS Number to get an exact result. The listing of the inmate will display their BOP Register Number.

Things to Know About Federal Inmate Search Results

  • The data in the Federal Inmate Locator is updated daily.
  • Hispanic's race can either be Black or White.
  • Release dates are only considered absolute if they have already been released. For those still in custody the release date is either UNKNOWN, subject to change, or projected.
  • Unless an inmate shows as being RELEASED, their location is subject to change, as inmates are occasionally moved to another facility with no notice.
  • The Freedom of Information Act (FOIA) allows certain information about Federal inmates to the general public if someone requests it. To obtain information beyond what is provided from the inmate locator and/or publicly available, submit a (Freedom of Information) FOIA request along with a properly completed Form DOJ-361. For further information, refer to the BOP's FOIA website.

Understanding The Federal Bureau of Prisons

The Federal Bureau of Prisons (BOP) is the agency responsible for overseeing and incarcerating pre-trial (indicted) and post-trial (convicted) inmates. Federal inmates differ from those in county jails and state prisons because the crime they are either being accused of or have been convicted of violates specific federal laws.

The Federal Bureau of Prisons has many different types of facilities that incarcerate inmates. That is because they deal with such a wide range of inmate types, from non-violent Wall Street tycoons serving a few years in a ‘Camp’ with no fences, to the most dangerous and deadly serial murderers who are only allowed to leave their cells and go into a small exercise cage for one hour per day.

When referring to a federal prison, you always place the acronym of the prison ‘type’ in front of the name (or location) of the prison.  For example, USP Allenwood is a United States Penitentiary in Allenwood, Pennsylvania. US Penitentiaries are always either medium or maximum-security facilities. They house the most violent, and in many cases, the longest-term prisoners in the BOP.  The only exception is the ADX (or ADMAX), a Supermax prison in Florence, Colorado that houses the ‘worst of the worst’ prisoners such as the late John Gotti, the Unabomber, serial killers who cannot mix with other inmates, and other incorrigibles such as convicted terrorists.

Federal Correctional Institutions (FCI), are classified as both medium and low-security facilities. The lowest security facilities, Prison Camps (FPC and SCP), allow for freedom of movement on the entire prison grounds outside of the security walls and razor wire. Prison Camp inmates handle much of the maintenance and upkeep of the complex. Americans have often heard these referred to as ‘Club Fed’, due to the fact that they are thought of as much less restrictive than a regular prison.

In addition to the standard lockups, the BOP maintains many Maximum-Security Detention Centers (FDC, MDC and MCC), Medical Facilities (FMC and MCFP), privately owned Correctional Institutions (CI), Con-Air Prisoner Transfer Centers (FTC) and Female Facilities (SFF).

Prior to an inmate’s release from the custody of the BOP, they will first transition into a Residential Reentry Center (RRM). Inmates in the ‘halfway houses’ are required to take responsibility for the cooking, cleaning and upkeep and by working a full-time job to subsidize the cost of the facility.  After their release from a BOP facility, every federal inmate must undergo several years of supervised release (probation) before they can experience the real freedom we all enjoy.
