A formal list of Q-Codes was instituted at the London Radiotelegraph Convention of 1912
The current codes were assigned meanings by the International Telecommunications Union in 1959

The QAA...QNZ series are reserved for the aeronautical service.
The QOA...QQZ series are reserved for the maritime services.
The QRA...QUZ series are for use by all services.
