What items are considered For Official Use Only?

"For Official Use Only" (FOUO) items refer to documents and materials that, while not classified, are sensitive and intended for internal government use. These may include internal memos, reports, and data that could compromise operations or privacy if disclosed. FOUO designations help protect such information from public release, ensuring it remains within authorized personnel. Organizations often have specific guidelines for the handling and dissemination of FOUO materials.
