A United Nations Specialized Agency





(Last updated on 8 January 2013)



The Postal History of ICAO provides an unusual approach to the history of the International Civil Aviation Organization (ICAO); this history is based on the philatelic material, i.e. stamps and covers, related to ICAO. The historical episodes of this Organization start from the Chicago Convention (1944); however, the predecessor Organizations and Conferences are a full part of this postal history.

NEW or MODIFIED chapters are indicated as of last update. Changes will be introduced on a cycle of approximately six months. Comments may be addressed to the following e-mail address: The Postal History of ICAO.
