What is Controlled Unclassified Information (CUI)?

CUI is Government-created or owned UNCLASSIFIED information that allows for, or requires, safeguarding and dissemination controls in accordance with laws, regulations, or Government-wide policies.  It is sensitive information that does not meet the criteria for classification but must still be protected.

Why is CUI important?

CUI policy provides a uniform marking system across the Federal Government that replaces a variety of agency-specific markings, such as FOUO, LES, SBU, etc.
Not every category or authority listed in the Registry will be applicable to DoD.

The DoD CUI Registry will give you information on every category to include a description of the category, required markings, national and DoD authorities, and examples.
