As well as being used by the United Kingdom, Noreen was used by Canada. It was widely used in diplomatic stations. According to the display note on a surviving unit publicly displayed at Bletchley Park in the United Kingdom, the system was predominantly used "by the foreign office in British embassies overseas where the electricity supply was unreliable."

Usage lasted from the mid-1960s through 1990.
