National Security Demands

National Security Letters are required administrative subpoenas issued by the Federal Bureau of Investigation in regard to counterterrorism or counterintelligence. These subpoenas are limited to non-content information, such as a list of phone numbers dialed or subscriber information.

Our reporting on National Security Letters and court orders issued pursuant to FISA (collectively “National Security Demands”) is governed by the USA Freedom Act. See Section 604 of the USA Freedom Act. That statute only permits us to report data in defined numeric ranges and for certain time periods.

Court orders issued pursuant to FISA may direct us to respond to government requests for content and non-content data related to national security investigations, such as international terrorism or espionage. 

Consistent with the above guidance, our report includes the range of National Security Letters and FISA demands served on us and the “customer selectors targeted” by those respective demands.2

2The term “customer selectors targeted” is statutory. See  18 U.S.C. § 1874.
