UN/LOCODEs (United Nations Code for Trade and Transport Locations) are codes for geographic locations that typically consist of five letters. The first two letters are the country code (ISO 3166-1 alpha-2); the next three letters define the location within the country. Optionally, numbers can be used if the combinations are not sufficient.
These codes are developed and updated by the United Nations Economic Commission for Europe (UNECE), a suborganisation of the United Nations.
The ISO-3166-1 coding list contains over 42,000 entries for all countries and the corresponding UN/LOCODEs. Here, locations that are significant for logistics in particular are listed. These include locations with a port or airport, a train station or intersections for trunk roads and border crossings. Examples for UN/LOCODEs: DE MUC–Germany, Munich or US NYC–USA, New York City.
The air and sea freight software CarLo inAIR&SEA can cover and integrate the entire transport sectors, regardless of whether it is a road, air or sea freight transport. The UN/LOCODEs are also integrated in the standard version of the software.
