This report reprints the text of the five National Security Letter (NSL) statutes as they now appear and as they appeared prior to amendment by the USA PATRIOT Act (to which form they would be returned under S.1125 and H.R. 1805). NSLs are roughly comparable to administrative subpoenas. Various intelligence agencies use them to demand certain customer information from communications providers, financial institutions, and consumer credit reporting agencies under the Right to Financial Privacy Act, the Fair Credit Reporting Act, the National Security Act, and the Electronic Communications Privacy Act.
