How to Use the BOP Inmate Locator for USP Atwater
The Federal Bureau of Prisons offers a free online tool called the Inmate Locator. It helps you find anyone in federal custody from 1982 to today. To use it, go to the BOP website and enter the person’s name, BOP ID, or registration number. The system will show their current location, housing unit, custody level, and projected release date. Because of the First Step Act, many sentences are being recalculated. This means release dates may change. Always check the locator again before making plans.
The locator updates daily. It pulls data directly from the BOP’s central database. You can search by first and last name, but results may show multiple people. Use the registration number for the most accurate match. The tool works on phones, tablets, and computers. It is free and does not require an account. If you can’t find someone, they may be in a different facility or recently transferred. Call USP Atwater at 209-386-0257 to confirm.
