What is the minimum marking for unclassified DoD documents containing CUI?

• A. "CUI" in the banner and footer of the document
• B. "U" in the banner
• C. FOUO in the banner
• D. No marking

Answer: (A)

The minimum marking for unclassified DoD documents containing CUI is to have "CUI" shown in the banner on the top and bottom of every page. This makes immediately clear that the content is controlled unclassified information and must be handled under CUI safeguarding rules, regardless of the document’s overall classification level. Using just a plain Unclassified indicator doesn’t signal the presence of CUI, so it wouldn’t meet the required protection marking. FOUO is an older label that isn’t the current standard for CUI, so it wouldn’t satisfy modern DoD marking guidance. Marking the document with no indication at all fails to warn handlers and isn’t compliant. Thus, the banner and footer "CUI" marking on each page is the appropriate minimum.
