What is the CUI Registry and its purpose?

• A. A centralized repository listing CUI categories, markings, and handling requirements used to standardize designation and protection.
• B. A registry of official DoD personnel responsible for CUI oversight.
• C. A system for tracking CUI destruction verification.
• D. A public directory of CUI disclosure requests.

Answer: (A)

The CUI Registry is a centralized repository of CUI categories, associated markings, and the handling requirements that go with each category. Its purpose is to standardize how information is labeled and protected across agencies so everyone applies the same markings and safeguards when creating, sharing, or storing CUI. By consulting the registry, personnel know which category applies, what marking to use, and the controls governing access, dissemination, storage, transmission, and destruction. This consistency supports compliant handling and reduces the risk of improper disclosure. It’s not a roster of people, a tool for tracking destruction, or a public directory of disclosure requests.
