For Official Use Only(FOUO)
A sensitivity designation for unclassified information that requires protection from unauthorized disclosure.
Overview
For Official Use Only (FOUO) is a marking applied to unclassified information that is sensitive and should not be released to the public. It is used across civilian and defense agencies to protect information that could cause harm if disclosed.
Why It Matters in GovCon
Contractors routinely receive FOUO materials — solicitations, technical documentation, or program information. mishandling FOUO can result in contract issues, security violations, and loss of trust. Proper safeguarding and disposal are required.
Key Details
- Unclassified: FOUO is not classified; it is a handling control, not a security classification.
- Safeguarding: Must be protected from unauthorized access; not for public release.
- Disposition: Must be properly destroyed or returned when no longer needed.
- Varies by Agency: DoD may use FOUO; other agencies use similar controls (e.g., SBU, CUI).
