UN/LOCODE is a geographic coding scheme developed and maintained by United Nations Economic Commission for Europe, a unit of the United Nations.

UN/LOCODE assigns more than 50000 code elements to locations with functions such as seaports, airports, rail and road terminals, post offices, border crossing points and other locations used in trade and transport in 234 countries.

UN/LOCODEs typically have five characters. The first two are letters, and come from the ISO 3166-1 alpha-2 country codes. Normally three letters will follow, but if there are not enough combinations, numbers from 2 to 9 can also be used. For airports, the three letters following the country code are not always identical to the IATA airport code. According to the secretary note for edition 2005-1 [1] 705 location entries show the differing IATA code.

Beside the abbreviation, UN/LOCODE also defines a spelling for each location that can be written without special characters. This is achieved by stripping off the diacritics from the (romanized) local name.
