What are UN/LOCODE Codes?

UN/LOCODE (United Nations Code for Trade and Transport Locations) is an international standard maintained by the United Nations Economic Commission for Europe (UNECE). Each code consists of a two-letter country prefix followed by a three-character location identifier, producing codes like USLAX (Los Angeles) or GBLON (London). The system covers over 100,000 locations across 193 countries, including seaports, airports, rail terminals, inland clearance depots, and border crossings.

In international trade, UN/LOCODE codes appear on vessel manifests, bills of lading, letters of credit, and customs declarations. Each location carries function codes that indicate its transport capabilities -- whether it operates as a port, airport, multimodal hub, or border crossing. Shipping lines, freight forwarders, and customs authorities rely on UN/LOCODE to standardize location references across different languages and national coding systems, reducing errors in documentation and cargo routing.
