The Correct Banner Marking for Unclassified Documents with CUI

Classified information is not the only type of sensitive data that requires careful handling. Controlled Unclassified Information, or CUI, represents a category of unclassified information that still demands strict protection due to legal, regulatory, or policy requirements. Understanding how to properly mark documents containing CUI is critical for compliance, information security, and operational integrity.

What Is Controlled Unclassified Information (CUI)?

Controlled Unclassified Information refers to information that requires safeguarding or dissemination controls pursuant to and consistent with applicable law, regulations, and government-wide policies. Unlike classified information, CUI is not classified under Executive Order 13526, but it still requires specific handling, storage, and marking protocols. This information can include privacy data, export-controlled technical data, critical infrastructure details, and other sensitive but unclassified materials.

Why Proper Banner Marking Matters

Banner markings serve as the first line of visual identification for sensitive documents. They immediately alert readers to the presence of CUI and provide instructions on handling, distribution, and destruction. Without proper markings, documents can be mishandled, improperly shared, or even lost, leading to regulatory violations, security breaches, and potential legal consequences. Consistent and correct banner markings ensure that all personnel, regardless of their familiarity with the content, can recognize the sensitivity of the material and act accordingly.

Standard Banner Marking Format for Unclassified Documents with CUI

The correct banner marking for an unclassified document containing CUI follows a specific format. At the top and bottom of each page, the banner should read:

CUI//FOR OFFICIAL USE ONLY

This marking must appear in bold, capital letters, and be clearly visible. The phrase "FOR OFFICIAL USE ONLY" is a subset marking that indicates the document contains CUI and specifies the level of restriction. The banner must be placed on every page of the document, including the title page, table of contents, and appendices.

Placement and Design of CUI Banners

The CUI banner should be positioned at the top of the page, typically in the header section, and repeated at the bottom in the footer section. The text should be in a contrasting color to ensure visibility, often black or dark blue on a white background. The font size should be large enough to be easily read but not so large as to dominate the page. Consistency in placement and design across all pages of the document is essential to maintain professionalism and compliance.

Additional Markings and Annotations

In addition to the banner, other markings may be required depending on the specific type of CUI. For example, if the document contains Privacy Act information, the banner might include an additional annotation such as:

CUI//PRIVACY

If the document is subject to specific handling caveats, those should be clearly indicated. For instance:

CUI//FOR OFFICIAL USE ONLY//NOFORN

This indicates that the information is CUI, for official use only, and not to be released to foreign nationals. Each additional marking must be relevant and accurate, as incorrect or excessive markings can lead to confusion or non-compliance.

Common Mistakes to Avoid

One of the most common mistakes is failing to mark every page of a document. Even if only one page contains CUI, the banner must appear on all pages. Another mistake is using incorrect or outdated terminology. For example, using "Sensitive But Unclassified" (SBU) is no longer acceptable under current CUI policy; "FOR OFFICIAL USE ONLY" is the correct designation. Additionally, some organizations mistakenly place banners only on the title page or omit them from appendices and references.

Training and Awareness

Proper marking of CUI documents is not just a technical requirement but also a matter of organizational culture. All personnel who handle, create, or distribute documents must be trained in CUI policies and banner marking procedures. Regular refresher training and awareness campaigns can help prevent errors and ensure that marking practices remain consistent and compliant.

Conclusion

The correct banner marking for unclassified documents containing CUI is a simple yet vital component of information security and compliance. By using the standard format—CUI//FOR OFFICIAL USE ONLY—and ensuring consistent placement and accuracy, organizations can protect sensitive information and meet regulatory requirements. Proper training and attention to detail further reinforce the importance of these markings in safeguarding controlled unclassified information.
