Resolve any 5-character code (e.g. USNYC → New York; DEHAM → Hamburg; NLRTM → Rotterdam) to its name, country, subdivision, transport functions (port, rail, road, airport, postal, …), IATA code and coordinates; search locations by name with country and function filters; or list every location in a country. UN/LOCODE is the standard used in shipping, logistics, customs and EDI. Ideal for supply-chain, freight, trade-compliance and logistics software.
