In the classification authority block, which item indicates when to declassify the information?

In the classification authority block, the item that indicates when to declassify the information is the date following the Original Classification Authority (OCA) name. This date is critical as it provides a clear reference for when the classified status of the document will expire, thus ensuring that the information will be reviewed and potentially declassified after a specified time.

In many cases, classification is not intended to be permanent, so this date plays an important role in the lifecycle of classified information. It helps facilitate appropriate handling and dissemination of information over time and ensures compliance with policies governing classification and declassification.

The other items in the classification authority block, such as the name of the OCA, the classification level, and the serial number, serve different purposes. The name of the OCA identifies the individual or agency responsible for the classification decision, the classification level indicates the sensitivity of the information, and the serial number can assist in tracking the document but does not directly relate to the declassification timeframe.
