UN/LOCODE, the United Nations Code for Trade and Transport Locations, is a geographic coding scheme developed and maintained by United Nations Economic Commission for Europe (UNECE). UN/LOCODE assigns codes to locations used in trade and transport with functions such as seaports, rail and road terminals, airports, Postal Exchange Office and border crossing points. The first issue in 1981 contained codes for 8,000 locations. The version from 2011 contained codes for about 82,000 locations.
UN/LOCODEs have five characters. The first two letters code a country by the table defined in ISO 3166-1 alpha-2. The three remaining characters code a location within that country. Letters are preferred, but if necessary digits 2 through 9 may be used, excluding "0" and "1" to avoid confusion with the letters "O" and "I" respectively.
For each country there can be a maximum of 17,576 entries using only letters (26×26×26), or 39,304 entries using letters and digits (34×34×34).
For the US, the letter combinations have almost all been exhausted. So in 2006, the Secretariat added 646 entries with a digit as the last character.
For airports, the three letters following the country code are not always identical to the IATA airport code. According to the Secretariat note for Issue 2006-2, there are 720 locations showing a different IATA code.
UN/LOCODEs are released as a table. An individual revision is officially referred to as an "issue". A discussion of the table's structure follows.

The fields are listed in the official order.
A change from the previous issue is indicated by one of the following characters in the first column:
Marked for deletion in the next issue
Change in location name (usually spelling)
Other changes in the entry (not location)
Entry added to the current issue
= Reference entry
Retained for certain entries in the USA code list ("controlled duplications")
The code is represented with a space between the alpha-2 codes of ISO 3166-1 country code and the 3-character element.
Names of locations should be shown using the 26 letters of the Roman alphabet with, where appropriate, diacritic signs as contained in ISO 10646-1/1993 or ISO 8859-1/1987.
The name of the location, but non-practicable Diacritics may be ignored and should not be converted into additional characters(e.g., Göteborg may be read as Goteborg, rather than Goeteborg, Gothenburg, Gotembourg, etc.).
Can contain an apostrophe, e.g. L'viv
The ISO 1 to 3 character alphabetic and/or numeric code for the administrative division (state, province, department, etc.) of the country, as included in ISO 3166-2/1998. Only the latter part of the complete ISO 3166-2 code element (after the hyphen) is shown.
Each defined function gets a classifier; the most important are:
Indicates the status of the entry by a 2-character code. The following codes are used at present:
The date the location was added or updated: 0207 is July 2002, 9501 is January 1995, etc.
The edition published in 2008 uses the value 0701 for additions, while in other cases the exact month is used like 9710, 0212.
For correlation purposes, the IATA code for the location is marked if different from the second part of the UN/LOCODE.
Some entries have coordinates in the database. They are represented as: ddmmN dddmmW, ddmmS dddmmE, etc.
The remarks column can among other things contain a hint to what specifically was changed (See data field - "Change").
AvailabilityUN/LOCODE is available on the UNECE website, where the latest release of UNLOCODE directories and background documents are listed. Complete UN/LOCODE code list may be downloaded in the format of.mdb (MS Access database), .txt (text file) and .csv (Comma-separated values). HTML pages are also displayed on the website by countries.
UN/LOCODE Data Maintenance Request system is web-based (http://apps.unece.org/unlocode/), which enables registered users to submit online requests for new UN/LOCODE entry modifications.
