  1. As information on number stations is generally classified, very few government organizations have released information about them. Those that have include the Czech Office for Foreign Relations and Information (, the Polish Institute of National Remembrance (, the Swedish Security Service (, and the National Archives of Latvia. Additionally, number stations have been involved in the publicly prosecuted espionage cases of Kim Hyon-hui (1987), Václav Jelínek (1988), the Cuban Five (1998), Ana Montes (2001), the Illegals Program (2010), and Andreas and Heidrun Anschlag (2011).
