10% of countries is still a large population, and given the list, a large portion of globally traded food.

You also didn't factor in GS1 being a member, which serves 115 countries. Surely all of them aren't also using PLU, but they wouldn't be a member if some portion of their base wasn't.

After going down the rabbit hole, too, I wish they just had a clear country listing vs having to read about the members. So dumb.
