What type of documents requires a "Declassify on" date?

The requirement for a "Declassify on" date specifically applies to classified documents that have an established timeframe for review or automatic declassification. This date indicates when the information may be declassified, ensuring that the classification status is reviewed at regular intervals or is automatically lifted at a predetermined point in time. This practice helps manage classified information effectively by setting clear timelines for the potential release of information, thus promoting transparency while also maintaining national security.

In contrast, documents without a security classification do not require a declassification date since they are not subject to restrictions on public access. Non-classified documents intended for public release also do not need a declassify date as they are already accessible by the public. Additionally, documents that contain solely personal information may not necessarily have a "Declassify on" date, as this does not pertain to national security interests and may be governed by privacy regulations instead.
