Apple is providing a complete historical list of National Security Letters (NSLs) received where Non-disclosure orders have been lifted and public disclosure is permitted. These NSLs and the related correspondence releasing the Non-disclosure requirement have been redacted for privacy purposes.
National Security Letters are issued by the Federal Bureau of Investigation and request non-content data, such as subscriber data (“name, address, length of service”), in national security investigations.
