Tips

  • Whatever you type in the search box — port name, country, or UN/LOCODE — the list narrows down instantly and case-insensitively.
  • Invoices and bills of lading often list the 5-character UN/LOCODE, so you can look up a port either from its name or from the code itself.
  • A UN/LOCODE starts with a 2-letter country code (ISO 3166-1) followed by a 3-letter location code, so searching by country alone can already narrow things down.
  • If a country has several major ports (such as Shanghai, Shenzhen, and Ningbo in China), searching by country name lets you compare them all at once.
  • When preparing shipping documents, it helps to note down the UN/LOCODEs of both the origin and destination ports beforehand for smoother data entry.

Frequently Asked Questions

A UN/LOCODE is a location code defined by the United Nations (UN/CEFACT) for trade and transport locations worldwide, including seaports, airports, and inland hubs. It consists of a 2-letter country code followed by a 3-letter location code, and it's used to uniquely identify places on trade documents and in logistics systems.

Both identify transport locations, but they are managed by different bodies for different purposes. UN/LOCODEs cover trade locations in general, including seaports and inland hubs, and are managed by the United Nations, while IATA/ICAO codes are managed by aviation industry bodies for flight operations.

It's commonly printed in the origin/destination fields of export and import invoices or bills of lading. You can use this tool to look up a code by port or country name and check that it's written correctly.

This tool covers 37 major world ports, so smaller regional ports and inland locations are not included. We plan to consider expanding coverage in future updates.

Side Note — Trivia about UN/LOCODEs

UN/LOCODE was developed in the 1980s by UN/CEFACT, the trade facilitation body of the United Nations Economic Commission for Europe (UNECE). It originally covered port cities, but today the list includes more than 100,000 locations, including inland cities without airports and border checkpoints.

Even at large ports with multiple terminals, a UN/LOCODE is generally assigned to represent the city or port as a whole rather than to each individual terminal. For example, the ports of Los Angeles and Long Beach sit right next to each other geographically, yet they carry distinct codes (USLAX and USLGB), so documents can clearly tell them apart.

The structure of a UN/LOCODE can also reflect regional patterns. Major Chinese ports all start with "CN," and the final three letters are usually derived from the English spelling of the port name, though this isn't a strict rule — Shanghai's "SHA" and other codes were often shaped by historical circumstances rather than a fixed formula.
