Which agency typically regulates the marking of classified information?

The agency that typically regulates the marking of classified information is the National Archives and Records Administration (NARA). This agency plays a critical role in overseeing the management and preservation of government records, including classified information. NARA establishes the standards for the creation, maintenance, and disposal of records across various federal agencies, ensuring that classified materials are handled in a consistent manner according to established guidelines.

NARA's involvement is particularly significant as it helps ensure that classified information is marked appropriately to reflect its sensitivity and to safeguard national security. The guidelines set forth by NARA are critical for maintaining clarity in the classification system and for ensuring compliance with the requirements of the executive orders governing national security information.

Other agencies, while they may have roles related to specific aspects of classified information, such as intelligence operations or law enforcement, do not have the overarching regulatory responsibility that NARA has when it comes to marking and managing classified documents.
