Do you have to put "U" in the banner/footer like the old "U//FOUO" format?

• A. No
• B. Yes
• C. Sometimes
• D. Only for specific document types

Answer: (A)

Under the CUI framework, the outdated practice of adding a U to the banner or footer (the old U//FOUO marking) isn’t required. Documents that contain Controlled Unclassified Information are marked with CUI, and may include the applicable CUI category or handling instructions, rather than the old U designation. This standardizes marks across the DoD and its partners, replacing the old unclassified shorthand with a clear CUI designation. So you don’t need to put a U in the banner or footer anymore—the presence of CUI (and the specific category, if applicable) communicates the handling requirements.
