[14] [DFN[ISO 3166]] は、[[国]]や[[地域]]に[[英数字]]の[[符号]]を割り当てた[[国際規格]]です。
* 種別

-- 3文字[[英字]]

** 特殊な符号
[20]
予約や[[私用]]の[[符号]]の扱いについては、 [[地域部分タグ]]も参照。
[33] [[ccTLD]] はほぼ [[ISO 3166]] ですが、一部例外があります。
[34] 正式な [[ccTLD]] 以外に独自の[[符号]]を勝手に割り当てて私的に使っていることがあります。

では[[私用]]の2文字[[国符号]]、3文字[[国符号]]、3文字数値符号の対応関係が規定されています。
[26] [[BR]] に従う[[証明書]]では、[[国]]の指定として適切な[[国]]符号が割り当てられていない時
[CODE[[[XX]]]] を使います [SRC[>>28]]。

- [4] ISO 3166-1 の2文字[[国名符号]]ならそこらじゅうに転がってますが、 -2 の地域名符号はないですね。 ISO 3166/MA も -1 は見れるようにしてるけど -2 は売ってる。
- [5] -2 の実体は各地域の地域名符号規格の寄せ集めらしい。例えば[[日本国]]の場合は JIS の[[都道府県名符号]] (数値) で [CODE[JP-01]] とか。
- [6] >>4-5 完全なのじゃなくてそういう部分的なのでよければ、検索すれば幾つか出てきますな。
[7] ISO 3166-1 の国名符号の商用利用は [[ANSI]]
に課金されるという話があって、
Unicode list で2003年3月に問題になっていました。
[[MichaelEverson]] が MA に問合せたところ、国名符号を使う規格なら実装しても問題なし、いけないのは国名リストを味付けした程度で販売することらしい、という感じですが、まだ確認を続ける、という段階のようなので、商用利用する時は気をつけたほうがいいでしょう。
