Is the use of U.S. Postal Service Priority Mail Express authorized for secrets outside of the continental U.S.?

The use of U.S. Postal Service Priority Mail Express for sending secrets outside of the continental U.S. is not authorized due to concerns surrounding security and the need for confidentiality. Sensitive information and classified materials are typically required to be sent through secure channels that are specifically designed to protect the contents from unauthorized access.

The Department of Defense has strict regulations regarding the transmission of classified and sensitive information, which includes the requirement that such materials be handled and transmitted through channels that are accredited for that purpose. This approach ensures that the data remains secure throughout its journey, which is essential for national security.

In contrast to other postal services, Priority Mail Express does not provide the necessary level of security and control required for transmitting secrets. Therefore, the conclusion is that this method of mailing is not authorized for such purposes, ensuring compliance with the regulations governing the handling of sensitive information.
