Restricted During and before World War II, the U.S. had a category of classified information called Restricted, which was below confidential. The U.S. no longer has a Restricted classification, but many other nations and NATO do. The U.S. treats Restricted information it receives from other governments as Confidential. The U.S. does use the term restricted data in a completely different way to refer to nuclear secrets, as described above.
