Controlled Unclassified Information (CUI)

Information that law, regulation or government-wide policy requires to have safeguarding or disseminating controls excluding information that is classified. Reference CUI Registry at

Certain unclassified information requiring safeguarding and dissemination controls mandated by statute or policy. Examples of such information within DOE include Official Use Only (OUO), Export Controlled Information (ECI), Unclassified Controlled Nuclear Information (UCNI), unclassified Naval Nuclear Propulsion Information (U-NNPI), and protected Personally Identifiable Information (PII). Within DOE other terms have been used, such as Unclassified Controlled Information (UCI) and Sensitive Unclassified Information (SUI), to refer to information that warrants protection as CUI. (Note: Current Government-wide efforts are under way to standardize CUI markings. Refer to, which will be updated for most current information.)
