To find information online for inmates, people can visit the website of the Federal Bureau of Prisons or state prison bureaus. For inmates incarcerated at federal prisons, the Federal Bureau of Prisons is a good place to search for information. It maintains a database of criminals held in federal prisons since 1982, and includes information such as name, prison term, date of birth and other details.
For inmates jailed prior to 1982, the Federal Bureau of Prisons refers visitors to the National Archives Records Administration. The Bureau also maintains a list of individuals held during sentences but never formally convicted of crimes. While its site lists only criminals convicted of federal crimes, the Bureau recommends contacting state department of corrections for in-state criminals.
