Look up or search UN/LOCODE — the United Nations Code for Trade and Transport Lo
Look up or search UN/LOCODE — the United Nations Code for Trade and Transport Locations (~116k locations, all countries). Pass `locode` for an exact code (e.g. USNYC or 'US NYC'). Or pass `query` to search location names, optionally filtered by `country` (ISO 3166 alpha-2) and `function` (port, rail, road, airport, postal, multimodal, fixed, border). Each result: locode, name, country, subdivision, transport functions, entry status, IATA code where it differs, and coordinates. UN/LOCODE is the standard location identifier in shipping schedules, EDI messages, and customs documents.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
