Somebodies lying (or at least being deceptive). I checked the link. There’s no mention of 20 countries anywhere. Nobody said 20 countries here either. Setting that pedantry aside. In fact, even if it were used by significantly fewer than twenty countries, the ones that without a doubt do use them are spread around the globe. Thus, they are used globally.
Well… if you check the link, it is like 20 country. Hardly a global standard.
