Criminal records are maintained by state and federal governments in the United States. In general, federal criminal records are kept by the FBI, while state criminal records are kept by state police agencies. However, there is some overlap between state and federal agencies, and some federal agencies maintain their own state criminal records.
Federal criminal records are available to the public, but there are some restrictions on who can access them. In most cases, you must have a legitimate reason for wanting to access someone's criminal record, such as conducting a background check for employment purposes.
