Price look-up code

PLU codes are used primarily in retail grocery stores or supermarkets, where they are keyed into point of sale systems by cashiers or by customers at self checkout machines when the produce is being weighed or counted.

[citation needed] Suppliers may coordinate with their retailers to use the same code in the retailer-assigned range for a specific product.

[citation needed] Some producers have obtained a license to place characters on stickers on PLU code labels, often as a promotion for a movie, television show or other media franchise.

[5] Although the collecting of PLU labels as a hobby already existed for a while, it became widespread through social media presence and fashion designs that use fruit stickers.

[citation needed] Although PLU labels are recognized globally and most chain supermarkets use them, they sometimes cause rejection of the fruits and vegetables they are attached to from being accepted for composting disposal.
