Authorized Classification Markings in U.S. Intelligence

Classification and dissemination control markings that may be used in the U.S. intelligence community are listed in an official register (pdf) that has recently been approved for release by the Office of the Director of National Intelligence.

The document includes authorized abbreviations and some non-U.S. dissemination control markings, along with citations to statutory or other authority and brief guidance as to proper use. The lightly redacted document does not include certain unpublished access controls or code word designations.
