What is the ICAO code for Melbourne Tullamarine?

• A. CYVR
• B. YYZ
• C. LFPG
• D. YMML

Answer: (D)

When you decode airport identifiers, ICAO codes are four-letter flight identifiers assigned to specific airports. The first letter indicates a broad region, and for Australia that region is represented with Y. The next letter helps narrow down to the country area, and the final two letters identify the exact airport. Melbourne Tullamarine is assigned the code YMML, so it uniquely matches that airport in the ICAO system.

For context, CYVR is Vancouver International in Canada, YYZ is Toronto Pearson in Canada, and LFPG is Paris Charles de Gaulle in France, illustrating how these four-letter codes map to different airports around the world. If you’ve seen traveler-focused three-letter codes (MEL for Melbourne), that’s the IATA format, which is different from the ICAO four-letter code YMML.
