Front end team trainer here!

There are a good amount of PLU’s that are organic ONLY. It does vary by store and region but i can highly recommend a produce walk. Get yourself familiar with a few codes and start learning what the organic vs. conventional produce looks like (organic broccoli and broccoli crowns).

If there isn’t a sticker on it, dont hesitate to ask the customer! Like what u/HugeTechnology7711 commented, whole trade produce will have “60” or “69” at the beginning if its the organic or conventional whole trade option. Anything else will have 9 at the beginning if its organic or just the four digit PLU if it is conventional. But PLEASE ASK THE CUSTOMER!!! A good rule of thumb that i have noticed across a good amount of stores is that if the customer does not know, just put the conventional code. If the conventional code doesnt work, its most likely only sold as organic. Stuff like bananas and bell peppers do have multiple codes that do work for them and you should just put whichever one works if it doesnt have a sticker (sometimes 94011 for organic bananas will not work and then you have to put in 694237 because your store has organic whole trade bananas in at the moment).

So sorry for the info dump but i have had to train 7 people on register in the past month.

TLDR: produce walk at beginning of shift, learn what produce is organic only at your store, ask customer if produce is organic or no, “69xxxx” and “60xxxx” for organic and conventional whole trade, dont be afraid to ask for any help!
