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), a unit of the United Nations. UN/LOCODE assigns codes to locations used in trade and transport with functions such as seaports, rail and road terminals, airports, post offices and border crossing points. The first issue in 1981 contained codes for 8,000 locations. The version from 2008 contained codes for about 60,000 locations.^[1]

[edit] Anglicized names

Beside the abbreviation, UN/LOCODE also defines a spelling for each location that can be written using only letters of the English alphabet. This was achieved by stripping off the diacritics from the romanized local name.^[2]

[edit] Structure

UN/LOCODEs have five characters. The first two characters are letters. They 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" avoids confusion between "O" and "0", and between "I" and "1".

For each country there can be at maximum 34*34*34 = 39 304 entries.

For the US, the 17575 possible combinations of 3-character codes have been almost exhausted. In 2006, the Secretariat added 646 entries to the 2006-2 issue of UN/LOCODE, in which the third position of 3-character codes is a digit from 2 to 9. The 2007 issue of UN/LOCODE contains 689 such US entries.

[edit] Loose consistency with existing IATA airport codes

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.^[2]

[edit] Official UN/LOCODE tables

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.

Explanations

• US NYC  for New York City in the United States. Subdivision is the U.S. state of New York (see ISO 3166-2:US). Function: port, rail, road, airport, postal. IATA code is NYC. Coordinates: 40°42′N 074°00′W / 40.7°N 74°W / 40.7; -74.

• DE BER  for Berlin (city) in Germany. Subdivision is the German state of Berlin (see ISO 3166-2:DE). Function: port, rail, road, airport, postal. IATA code is BER. Coordinates: 52°31′N 013°23′E / 52.517°N 13.383°E / 52.517; 13.383.

• DE TXL  for Berlin-Tegel Airport in Germany. Function: airport. IATA code is TXL.

• FR PAR  for Paris (city) in France. Subdivision is the French department of Paris (see ISO 3166-2:FR). Function: port, rail, road, postal.

• GB PAR  for Par in United Kingdom. Subdivision is the English county of Cornwall (see ISO 3166-2:GB). Function: port.

• SE GOT  for Göteborg (Goteborg without diacritics) in Sweden. Subdivision is the Swedish county of Västra Götaland (see ISO 3166-2:SE). Function: port, airport, postal. The IATA code of XWL indicated in the table is that of a train station in the city centre of Göteborg (though not the Central Station), while the IATA code for the main airport (Göteborg-Landvetter Airport) is actually GOT. It also has a separate reference entry showing an alternate spelling of Gothenburg.

[edit] Data fields

The fields are listed in the official order.

[edit] Ch (Changes)

A change from the previous issue is indicated by one of the following characters in the first column:

+  Additions to the issue

#  Change in location name (usually spelling) Note: Not defined in the manual [1]

|  Change other than location name

X  Entries marked for deletion in the next issue

=  Reference entry

!  US locations with duplicated IATA code, under review

[edit] Locode

The code is represented with a space between the country code and the 3-letter element.

[edit] Name

The name of the location.

[edit] Name Without Diacritics

The name of the location, but all non-latin-base characters are converted.

Can contain ' e.g. L'viv

[edit] SubDiv (Subdivision)

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.

[edit] Function

Each defined function gets a classifier; the most important are:

• 1 = port (for any kind of waterborne transport)
• 2 = rail terminal
• 3 = road terminal
• 4 = airport
• 5 = postal exchange office
• 6 = Inland Clearance Depot – ICD or "Dry Port", "Inland Clearance Terminal", etc.
• 7 = fixed transport functions (e.g. oil platform)"; the classifier "7" is reserved for this function. Noting that the description "oil pipeline terminal" would be more relevant, and could be extended to cover also electric power lines and ropeway terminals.
• B = Border crossing function

[edit] Status

Indicates the status of the entry by a 2-character code. The following codes are used at present:

• AA: Approved by competent national government agency
• AC: Approved by Customs Authority
• AF: Approved by national facilitation body
• AI: Code adopted by international organisation (IATA or ECLAC)
• AS: Approved by national standardisation body
• RL: Recognised location - Existence and representation of location name confirmed by check against nominated gazetteer or other reference work
• RN: Request from credible national sources for locations in their own country
• RQ: Request under consideration
• RR: Request rejected
• QQ: Original entry not verified since date indicated
• XX: Entry that will be removed from the next issue of UN/LOCODE

[edit] Date

The date the location was added or updated: 0207 is July 2002, 9501 is January 1995, etc.

Observation: The edition published in 2008 contains for additions the value 0701, while in other cases the exact month is used like 9710, 0212.

[edit] IATA

The IATA code for the location if different from the second part of the UN/LOCODE.

[edit] Coordinates

Some entries have coordinates in the database. They are represented by two numbers: the first followed by either N or S, the second by either E or W.

[edit] Remarks

The remarks column can among other things contain a hint to what specifically was changed (See data field - "Change").

[edit] Errors

In 2006-07 IQ IRB for Irbil was added while IQ ABL Arbil with almost the same coordinates existed. In the 2007 edition IQ ABL gets marked for deletion and IQ EBL Erbil International Apt is added to the database, but with a different coordinates, reflecting the distance between airport and city. The error is to delete ABL and to insert IRB.

Occasionally locations are listed twice; this is not necessarily an error. In issue 2006-1, ARSMC San Miguel de Tucuman (functions 2,3) was added while ARTUC Tucuman (function 1) already was in the list. The coordinates are with very little deviation the same. Also in 2006-1, ARSSJ San Salvador de Jujuy was added (function 4) while ARJUJ Jujuy (functions 1,2,3,5) already existed.

2007 added a 2nd code for Bánovce Nad Bebravou.

 SK  BAN Bánovce Nad Bebravou --3----- RL 0701 4843N 01815E SK  BNB Bánovce nad Bebravou -23--6-- RL 0607 4843N 01815E 

The 2007 edition contains character encoding errors in the .txt and .csv files. The name for the new code FR ONM Moёlan-sur-Mer does not show the ё correctly. In the .mdb file it is encoded correctly but the column "NameWoDiacritics" contains the name with diacritics .i.e. "Moёlan-sur-Mer". Users who cannot access .mdb files, cannot obtain from the website a correct list for their databases.

Another error from 2007 code list:

   DE  GXD Gross-Umstadt Gross-Umstadt HE --3----- RL 0201 4952N 00855E + DE  UMS Gross-Umstadt Gross-Umstadt HE -23----- RL 0701 4952N 00856E

[edit] 2009-1

The 2009-1 release added for Ukraine several entries where the longitude to big by power of 10. Ranging from 23230E to 38829E, they are outside what would constitutes an eastern longitude. Apart from Nikolayev, now also Ivano Frankovsk and Chuguyev have two entries. For all three the romanized spelling varies.

[edit] Problems

Some entries do not have coordinates, so it is not clear where they actually refer too. If an IATA code changes, then the UN/LOCODE could also be considered to have changed.
