Hemisphere differs from – and far exceeds in scope – the National Security Agency’s phone record collection program, called Section 215, as the NSA maintains its own database and stores records for just five years. The Hemisphere database stores call detail records (CDR) dating as far back as 1987. It is not known whether other carriers including Verizon, T-Mobile, and Sprint, have a similar arrangement with DEA to allow access to their call switches. What is clear: all calls from those carriers which pass through AT&T switches are immediately entered into the database.
