In the United States, there are separate federal and state prison systems. When performing a prison records search, it is important to use the correct inmate locator database. The Federal Bureau of Prisons (BOP), for example, provides an online inmate locator that only includes federal inmates.

If an inmate has been transferred between California State and Federal prisons, it may be necessary to perform more than one Inmate Search.
