When shopping for fresh produce, you’ve probably noticed the small stickers on fruits and vegetables. While they might seem like a minor detail, these stickers serve several important purposes. They provide key information about the produce’s origin, type, and price, helping both consumers and retailers. More importantly, they can reveal how the produce was grown—an essential factor for those mindful of their health and environmental impact.

Decoding PLU Codes on Fruit Stickers

PLU (Price Look-Up) codes are numerical identifiers used worldwide to classify bulk produce. Standardized by the International Federation for Produce Standards (IFPS), these codes help retailers manage inventory and pricing. But beyond that, understanding PLU codes allows consumers to make informed choices about the food they eat.

What PLU Codes Reveal About Your Produce

The number of digits in a PLU code—and the first digit in a five-digit code—hold specific meanings:

• Four-digit PLU code (e.g., 4011) → Conventionally grown produce
• Five-digit PLU code starting with 9 (e.g., 94011) → Organic produce
• Five-digit PLU code starting with 8 (e.g., 84011) → Genetically modified (GMO) produce

Genetically Modified (GMO) Produce: What to Know

Fruits and vegetables with a five-digit PLU code starting with 8 are genetically modified. GMOs are engineered to enhance traits like pest resistance, longer shelf life, or increased yield. While many scientific bodies consider them safe, some consumers avoid them due to concerns over long-term health effects, ethics, or environmental impact.

Conventionally Grown Produce: Pros and Cons

Conventionally grown produce carries a four-digit PLU code and is cultivated using traditional farming methods, often involving synthetic fertilizers, pesticides, and herbicides. These methods improve yield and lower costs but may raise concerns about chemical residues and environmental sustainability.
