Subject: Please clarify which information is CUI and how to handle it

Hello [contract or customer point of contact],

We are checking the information we receive and create for [approved contract or work reference]. We need help confirming whether [general description or restricted reference] is CUI, or which handling instructions apply.

Please answer the questions below or forward them to the appropriate government originator or office responsible for the contract.

1. Which information you supply and which deliverables we create are identified as CUI?
2. Which CUI categories apply, and which laws, regulations, or government-wide policies provide the basis for protecting the information? Please include the marking instructions and references to the contract or supporting documents.
3. Who should we ask about items with no markings, older markings, or markings that may be incorrect?
4. How should we protect and send the information while we wait for an answer?

Please reply in writing through our approved communication route. We can share restricted references through that route if you need them.

Thank you,
[authorized company contact]

Do not send the request, contract records, CUI, or supporting evidence to Purposeful Security. Keep meeting the protection and reporting duties that already apply while you seek an answer.
