以前查过 4 digits code for fruits

不代表 水果的 种类 or variaties.

刚刚又查了:

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:
