The Federal Bureau of Investigations (FBI) assigns anyone who has a felony criminal record an FBI identification number. This number serves to track the offender as he progresses through the system and to identify him should he commit a new offense. Once a felon is released from federal prison on parole, he has a permanent record in the Federal Bureau of Prisons. The system tracks all federal prisoners held since 1982. While states and local prisons also use FBI numbers, they use a separate tracking system, and parolees who are under those jurisdictions must be tracked separately.
Go online to the website for the U.S. Department of Justice, Federal Bureau of Prisons.
Enter the inmate's first name, spelled correctly. This step must match exactly. "Jon" will not match with "John" or "Jonathan."
Enter the inmate's last name, spelled correctly. First and last name fields are asterisked with red, as these are the only two mandatory fields.
Enter sex and race, if known. These fields are optional.
Hit the "search" key. This will pull up the inmate's or parolee's record. Her FBI number is located there.
