What Does FOUO Stand For?

FOUO stands for For Official Use Only

FOUO, or For Official Use Only, is a designation used by government and certain organizations to indicate that specific information is sensitive and intended solely for authorized personnel. Such information is not classified but is restricted from public disclosure to protect interests such as national security, privacy, and operational integrity. Access to FOUO material is typically limited to those with a legitimate need to know, ensuring that confidential data remains secure.
