欧盟的官方代码在哪里定义？
Where is an official code for the European Union defined?
ISO 3166 或 UN.M49 中没有欧盟代码。 CLDR 声明其自己的列表不包含欧盟的代码。我看到使用了代码 "EU"，但我找不到包含它的任何官方列表。它是否在任何官方代码列表中？
事实证明，它本身不在列表 中，但代码 EU 由 ISO 3166 维护机构正式 "reserved"代表欧盟。这在 old version of the Maintenance Agency FAQ:
中讨论
You can use EU for the name European Union. Please note that this is
not an official ISO 3166-1 country code. The European Union is not a
country but rather an organization. As such it is not eligible to be
formally included in ISO 3166-1. Recognizing, however, that many users
of ISO 3166-1 have a practical need to encode that name the ISO
3166/MA reserved the two-letter combination EU for the purpose of
identifying the European Union within the framework of ISO 3166-1.
