The fourth line must contain?

The fourth line must contain?

• A. The distribution statement or dissemination controls applicable to the document.
• B. The phone number or office mailbox.
• C. The office making the determination.
• D. A code for the CUI category.

Answer: (B)

In DoD CUI document markings, the header follows a fixed format, and the fourth line is reserved for a direct point of contact for the document. Including the phone number or office mailbox there ensures that anyone who needs clarification about dissemination controls or access can quickly reach the originator or the responsible office. It streamlines requests for permission, further classification, or special handling without forcing readers to search the document for who to contact. Other pieces of information, like the broader dissemination controls, the office that made the determination, or the CUI category code, appear on other lines or sections of the marking. The contact line is specifically for providing an immediate channel to obtain or verify access and handling details.
