Which agency assigns the Do Not Issue (DNI) notification?

• A. Department of Homeland Security
• B. TSA
• C. FBI
• D. Department of Justice

Answer: (B)

Do Not Issue notifications are about who controls credentialing and access decisions for transportation security. The Transportation Security Administration handles the credentialing and security-screening processes that determine who can receive credentials or access to secure areas in transportation settings. When there are concerns about an individual’s eligibility, TSA flags them with a Do Not Issue notification to prevent credential issuance. The other agencies—Department of Homeland Security as a whole, the FBI, and the Department of Justice—focus on investigations, enforcement, and policy, not on the direct issuance of transportation security credentials. So the agency that assigns a Do Not Issue notification is the Transportation Security Administration.
