What is a UN/LOCODE?
UN/LOCODE (United Nations Code for Trade and Transport Locations) is an international standard maintained by UNECE that assigns a unique five-character code to ports, airports, inland freight terminals, and other locations relevant to international trade and transport.
Each code consists of two parts: a two-letter ISO 3166-1 country
code followed by a three-character location identifier. For example,
GBLON represents London, United Kingdom - where
GB is the country code and LON identifies
the specific location.
What Does the UN/LOCODE Directory Contain?
The directory covers over 100,000 locations across more than 240 countries and territories. Each entry includes:
- Location name and country - the official name and administrative subdivision
- Geographic coordinates - latitude and longitude of the location
- Function codes - indicators for the type of transport hub (port, airport, rail terminal, road terminal, postal exchange, border crossing, etc.)
- Status - whether the entry is approved, pending, or marked for change
Where are UN/LOCODEs Used?
UN/LOCODEs are a fundamental building block of international logistics:
- Shipping and freight - bills of lading, customs declarations, and container tracking systems reference ports and terminals by their UN/LOCODE
- Trade documentation - commercial invoices, certificates of origin, and letters of credit use UN/LOCODEs to identify places of loading and discharge
- Supply chain software - ERP systems, TMS (Transport Management Systems), and WMS (Warehouse Management Systems) use UN/LOCODEs as standard location identifiers
- Customs and border agencies - government systems worldwide use UN/LOCODEs in electronic customs filings and clearance processes
Why Look Up a UN/LOCODE?
If you encounter a UN/LOCODE in a shipping document, trade database, or logistics system, you may need to find its geographic coordinates for mapping, determine its timezone for scheduling, or identify nearby alternative locations. This tool resolves any UN/LOCODE to its full location details - coordinates in every format, timezone with current UTC offset, elevation, and the nearest neighbouring UN/LOCODEs.
You can also work in reverse: paste any set of coordinates and the tool will show you the closest UN/LOCODEs to that position - useful when you need to identify the nearest port or terminal to a given point.
Frequently Asked Questions
What is a UN/LOCODE?
A UN/LOCODE is a five-character code that identifies ports, airports, inland freight terminals, and other transport-related locations worldwide. The first two characters are the ISO country code (e.g., GB for United Kingdom) and the last three identify the specific location (e.g., LON for London), giving GBLON.
How many UN/LOCODEs are there?
The directory contains over 100,000 locations across more than 240 countries and territories. It is maintained by UNECE and updated several times per year as new trade locations are added.
How do I find the UN/LOCODE for a location?
Type a UN/LOCODE directly into the converter above (e.g., GBLON for London) to look up its coordinates, timezone, and nearby locations. If you have coordinates instead, paste them in and the converter will show the nearest UN/LOCODEs to that position.
What information does a UN/LOCODE contain?
A UN/LOCODE itself is a five-character identifier, but the directory associates each code with a location name, country, subdivision, geographic coordinates, and function codes indicating whether the location is a port, airport, rail terminal, or other type of transport hub.
