PLU codes

**PLU codes**

PLU codes, or Price Look-Up codes, are numerical labels used primarily in grocery stores to identify bulk produce and other items at checkout. These standardized codes help cashiers quickly ring up products without weighing or individually scanning each item. Understanding PLU codes can also assist consumers in distinguishing between conventionally grown, organically grown, and genetically modified produce. This post explores what PLU codes are, how they work, and why they matter for both shoppers and retailers.
