ISO 3166-2 is part of the ISO 3166 standard published by the International Organization for Standardization (ISO), and defines codes for identifying the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1. The official name of the standard is ''Codes for the representation of names of countries and their subdivisions – Part 2: Country subdivision code''. It was first published in 1998. The purpose of ISO 3166-2 is to establish an international standard of short and unique alphanumeric codes to represent the relevant administrative divisions and dependent territories of all countries in a more convenient and less ambiguous form than their full names. Each complete ISO 3166-2 code consists of two parts, separated by a hyphen:〔(【引用サイトリンク】 title=ISO 3166-2 )〕 * The first part is the ISO 3166-1 alpha-2 code of the country; * The second part is a string of up to three alphanumeric characters, which is usually obtained from national sources and stems from coding systems already in use in the country concerned, but may also be developed by the ISO itself. Each complete ISO 3166-2 code can then be used to uniquely identify a country subdivision in a global context. Currently more than 4000 codes are defined in ISO 3166-2. For some countries, codes are defined for more than one level of subdivisions. ==Current codes== The following table can be used to access the current ISO 3166-2 codes of each country, and comprises three columns: * Entry — ISO 3166-1 alpha-2 code, click to view the ISO 3166-2 codes of the country * Country name — English short country name officially used by the ISO 3166 Maintenance Agency (ISO 3166/MA)〔(【引用サイトリンク】 title=Country names and code elements )〕 * Subdivisions assigned codes — Name and number of subdivisions assigned codes in ISO 3166-2; if there are more than one level of subdivisions, the first-level subdivisions are shown in ''italics'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ISO 3166-2」の詳細全文を読む スポンサード リンク
