If a loved one has been sentenced to federal prison, one of the first questions families ask is: Where are they?
The Federal Bureau of Prisons (BOP) provides an online Federal Inmate Locator that allows the public to search for individuals currently in federal custody or released after 1982.
Understanding how to use this system can help families locate inmates, confirm prison designation, and begin planning for communication, visitation, and release preparation.
What Is the Federal Inmate Locator?
The BOP Inmate Locator is an official database maintained by the Federal Bureau of Prisons that allows users to search for federal inmates using basic identifying information.
The system can identify:
- The federal prison where an inmate is housed
- The inmate’s register number
- Projected release date
- Age and basic identifying information
This tool is often the fastest way for families to learn where a loved one has been designated after sentencing.
How to Search the Federal Inmate Locator
You can search the BOP inmate locator using two main methods:
Search by Name
- First name
- Last name
- Age (optional)
- Race (optional)
Search by Inmate Register Number
If you know the inmate’s BOP register number, the search becomes much easier and more accurate.
Register numbers usually look like this:
12345-678
Why an Inmate May Not Appear Immediately
After sentencing, it may take several days or weeks for an inmate to appear in the locator system. This happens because:
- The inmate is still in U.S. Marshals custody
- The designation process has not been completed
- The BOP database has not yet been updated
During this period, families often have difficulty determining where someone is being sent.
For more information about what happens during this phase, see our guide on
What to Do Before Sentencing.
How Federal Prison Designation Works
Before appearing in the BOP inmate locator, an individual must first be designated to a federal prison by the Bureau of Prisons.
Designation decisions are heavily influenced by the Presentence Investigation Report (PSR), which contains detailed information about the defendant and the offense.

Understanding Federal Prison Placement
Once an inmate appears in the BOP system, families will be able to see the facility where the person is incarcerated.
Federal prisons are divided into different security levels, including:
- Federal Prison Camp (minimum security)
- Low security federal prisons
- Medium security federal prisons
- High security penitentiaries

What Families Should Do After Finding an Inmate
Once you locate an inmate, several important steps should follow:
- Confirm the facility location
- Set up phone and email communication
- Review visitation policies
- Begin planning programming and release strategy
Many inmates can reduce time in prison through programs such as the First Step Act or the Residential Drug Abuse Program (RDAP).

When the BOP Makes Mistakes
In some cases, the Bureau of Prisons may incorrectly calculate release dates or earned time credits.
If this happens, inmates can challenge these decisions through the BOP Administrative Remedy Program.
