Finding Someone at FCI Three Rivers: How to Use the BOP Inmate Locator
Trying to confirm whether someone is at FCI Three Rivers? The Federal Bureau of Prisons (BOP) Inmate Locator is the fastest way to check.
The BOP Inmate Locator covers federal inmates incarcerated from 1982 to the present. If you're searching for someone who was in federal custody before 1982, they may not appear - even if they were definitely in BOP custody at some point.
The BOP Inmate Locator is your main tool for checking whether someone is in federal custody and confirming they're at FCI Three Rivers. If you have multiple pieces of information - a name and a register number, for example - use them. Small details speed things up and improve accuracy.
If you have the person's BOP register number, enter it in this exact format: #####-###. Getting the format right prevents frustrating "no results" messages that are really just formatting errors.
Watch the format: The locator expects an exact match. A missing digit, swapped numbers, or a register number entered in a different format can keep the person from showing up - even if they’re in the system.
No results? Double-check what you typed. The locator requires exact matches - "John Doe" won't pull up "Jon Doe," and one wrong digit in a register number can derail the whole search. Slow down and verify the spelling and numbers before assuming the person isn't there.
Keep in mind: if the person was in federal custody before 1982, they may not appear in the locator at all. For older records, the BOP directs people to the National Archives (NARA).
Need more detailed records than the public locator provides? You can submit a Freedom of Information Act (FOIA) request. Complete Form DOJ-361 and mail it to: Federal Bureau of Prisons, Attn: Inmate Locator, 320 First St., N.W., Washington, DC 20534.
If the locator itself isn't working - pages won't load, searches keep erroring out - head to the BOP's "Contact Us" page and send a Technical Issue email. That's the right route when the problem is the tool, not your search details.
