The airport code ROA refers specifically to Roanoke, Virginia. Each airport in the United States has a unique three-letter code assigned by the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA). These codes are reflective of the locations they represent, and for ROA, it clearly corresponds to Roanoke Regional Airport located in Roanoke, Virginia.
