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 http://www.unece.org/cefact/locode/loc051sec.pdf 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.
