以前查過 4 digits code for fruits

不代表 水果的 種類 or variaties.

剛剛又查了：

A four-digit code on a piece of fruit is a Price Look-Up (PLU) code that indicates the produce was conventionally grown, meaning it was produced using conventional farming methods, which often include the use of synthetic fertilizers and pesticides. 

所有跟帖：
