===Data fields===
The fields are listed in the official order.

: {{mono|X}}&nbsp; Marked for deletion in the next issue
: {{mono|#}}&nbsp; Change in location name (usually spelling)

====Locode====
:The code is represented with a space between the alpha-2 codes of ISO 3166-1 country code and the 3-character element.

====Name====
: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.

====Name Without Diacritics====
: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]]

====SubDiv (Subdivision)====
:The [[International Organization for Standardization|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.

====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 [[Cableway|ropeway]] terminals.
:* B = Border crossing function
:* 0 = function not known, to be specified

: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.
