MANDATORY CUI BANNER MARKING
I
t is mandatory to include a banner marking at the
top of each page denoting Controlled Unclassified
Information.
It is optional, but a best practice to include the
banner marking on the bottom in addition to the top.
The content of the CUI banner marking must be
inclusive of all CUI within the document and must be
the same on each page.
There are two kinds of CUI: Basic and Specified.
If the laws or regulations, or Government-wide policy
that pertains to your information is listed in the CUI
Registry as a Specified Authority, then you must mark
the CUI based in that authority as “CUI Specified” on
the banner. Information marked as “CUI Basic” does
not require specific protection.
The CUI banner marking may include up to three
elements:
1. The CUI Control Marking (mandatory) may
consist of either the word “CONTROLLED” or the
acronym “CUI.”
2. CUI Category or Subcategory Markings
(mandatory for CUI Specified). These are
separated from the CUI Control marking by a
double forward slash (//). When including multiple
categories or subcategories in a banner marking,
they must be alphabetized and are separated by a
single forward slash (/).
3. Limited Dissemination Control Markings.
These are preceded by a double forward slash (//)
to separate them from the rest of the CUI banner
marking. When a document contains multiple
Limited Dissemination control markings, those
Limited Dissemination control markings must be
alphabetized and separated from each other with
a single forward slash (/).
