Declassification Guidance 002-98 -- NSA Fund Cite
In keeping with the spirit of Executive Order 12958 to protect only the information that must be protected in the interest of national security, the Office of Information Security Policy (N5P6) in coordination with N44 has determined that there is not sufficient cause or justification to continue to protect the unclassified NSA fund cite (i.e. - - - - 45 XXXX S18119XXXX). Effective immediately, the unclassified NSA fund cite will no longer require protection with the FOR OFFICIAL USE ONLY caveat.
Generally fund cites can be found in, but not limited to, documents such as contracts and travel orders.
