PLU (Product Look Up) codes are 4 or 5 digit numbers which have been used by supermarkets since 1990 to make check-out and inventory more efficient and accurate. They ensure that the correct price is paid by consumers and identify the product; e.g., whether or not it is conventionally or organically grown.
So what exactly do those PLU numbers mean?
8 -genetically modified
3 and 4- conventionally grown with pesticides and fertilizers. (1)
The remaining numbers indicate the type of produce
For example if the sticker label number is 94024, you would have an organic pear Bartlett/Williams/ WBC, small. If the pear was large the number would be 94409.
You won’t see a lot of produce labeled with a sticker starting with the number 8, mainly because genetically modified versions of corn, soybeans, canola, cotton, papaya, and squash are now widely sold. Because PLU codes aren’t mandatory, companies can simply label those items as conventional.
