What is UN/LOCODE in relation to station codes?

• A. It is a three-character code system used for weather stations.
• B. It is a five-character code system for places used in international trade and logistics, complementing IATA/ICAO for location identification.
• C. It is a six-character code for airline routes.
• D. It is a two-character country code.

Answer: (B)

UN/LOCODE is a five-character system that uniquely identifies places used in international trade and transport. It combines the two-letter ISO country code with a three-character location code, so a city or port in the United States would appear as USNYC, for example. This standard helps streamline shipping, customs, and logistics documentation by providing a consistent way to reference locations, and it complements airport- and location-specific identifiers from IATA and ICAO. It covers a wide range of locations beyond airports, including ports, rail terminals, and inland freight depots. It’s not a code for weather stations or for airline routes, which is why this description matches UN/LOCODE.
