Unclassified Controlled Information
HQ Office of Classification, 301-903-3526
Unclassified Controlled Information (UCI) is information that cannot be classified for legal or
operational reasons, but that is still sufficiently sensitive that its unauthorized dissemination is
prohibited. UCI is protected through marking, access control, physical protection, and other
requirements that restrict reproduction, transmission, destruction, and dissemination.
UCI includes, but is not limited to:
- DOE Official Use Only (OUO). Certain unclassified information that may be exempt from
release under the Freedom of Information Act (FOIA) and has the potential to damage
governmental, commercial, or private interests if disseminated to persons who do not need to
know the information to perform their jobs or other DOE-authorized activities. While there are
several categories of OUO information, one category requires special attention: Personally
Identifiable Information (PII). PII is identified as OUO under FOIA exemption 6 and, as such,
must not be released to anyone who does not have a legitimate need to know the information.
- An individual's social security number or date of birth
- An individual's medical conditions or criminal history
- Personnel matters in which administrative action, including disciplinary actions, may be taken
- An employee's performance evaluation rating
- An evaluation of a candidate for employment or security clearance
If you have questions about the protection of PII, call the Office of the Chief Information
Officer, (202) 586-0166.
- Unclassified Controlled Nuclear Information (UCNI). Certain unclassified but sensitive information concerning nuclear material, nuclear weapons, and their components the distribution of which is controlled under the Atomic Energy Act.
- Other-Agency Controlled Information is UCI created by other Agencies. Examples include Department of Defense information known as "For Official Use Only" (FOUO) and State Department information known as "Sensitive but Unclassified" (SBU). These other Agencies' UCI markings are equivalent to DOE's OUO markings, and documents with such markings must be protected.
