Ever stood in the produce aisle, clutching a single, slightly bruised Hass avocado, and wondered why on earth the tiny sticker says 4046? You’re not alone. Most people just swipe the sticker off and toss it in the trash without a second thought, but those four or five digits—technically called Price Look-Up (PLU) codes—are actually a secret language used by retailers worldwide. Honestly, once you know how to read a produce codes list with pictures, grocery shopping starts feeling a lot more like a decoded mission and less like a chore. It’s not just about the price. It’s about how that food was grown, whether it’s genetically modified, and if you’re actually getting the organic honeycrisp apple you’re paying six dollars for.
The Secret Math of the Produce Sticker
PLU codes aren't just random numbers some guy in a warehouse made up. They are strictly regulated by the International Federation for Product Standards (IFPS). This global body ensures that a 4011 is a yellow banana whether you’re shopping in a high-end market in Manhattan or a roadside stall in New Zealand.
Most codes you'll see are four digits. These almost always start with a 3 or a 4. If you see a four-digit code, it means the produce was "conventionally grown." In plain English? It probably had some pesticides or synthetic fertilizers involved in its journey to the shelf. It’s the standard stuff.
But then things get interesting. Sometimes you'll see a five-digit code. If that code starts with a 9, you’ve struck organic gold. For example, while a standard banana is 4011, an organic one is 94011. It’s a simple prefix that changes everything about the price and the farming method. You’ve probably heard rumors about codes starting with an 8. For years, the internet insisted an 8 meant the food was GMO (Genetically Modified Organism). While the IFPS did technically reserve the 8 prefix for GMOs back in the day, it was rarely used because, let's be real, no brand wants to advertise that to a skeptical public. As of recent updates, the 8 prefix is actually being transitioned to help categorize more conventional items as the 3 and 4 series run out of numbers.
Why pictures actually matter here
Seeing a produce codes list with pictures is vital because a number alone doesn't tell the whole story. Take the humble apple. There are dozens of varieties. A 4131 is a Fuji apple. It’s sweet, crisp, and has those distinct red and yellow stripes. Compare that to a 4017, which is a Granny Smith. If you’re making a pie, you want the 4017. If you're snacking, you probably want the 4131. Seeing the image next to the code helps you verify that the cashier (or the person who stocked the bin) didn't make a mistake. Mistakes happen. You don't want to pay the premium price for a Honeycrisp (4101) if you're actually holding a Gala (4133).
A Breakdown of Common Codes You’ll See Every Day
Let's get specific. If you walk into a Kroger, Safeway, or Whole Foods today, these are the heavy hitters you’re going to encounter.
The Banana Dynasty
The most famous code in the world is 4011. It’s the yellow Cavendish banana. It’s the most scanned item in almost every grocery store in North America. If you see a 94011, it's the organic version. Occasionally, you might see small "baby" bananas; those usually carry a 4231.
Apples: The Most Complex Category
Apples have more codes than almost any other fruit.
- 4017: Granny Smith (Green, tart).
- 4133: Gala (Small, reddish-orange).
- 4131: Fuji (Large, sweet).
- 4101: Honeycrisp (The expensive ones).
- 4015: Red Delicious (The ones that look great but taste like sand).
Citrus and the "Size" Factor
Citrus codes often depend on the size of the fruit. A large Navel orange is 4012, while a small one is 3107. This matters for the store's inventory, but for you, it’s a good way to check if you’re being charged for a "large" fruit when you’re holding a "medium" one. Lemons are almost always 4033, and limes are 4048.

The GMO Myth and Modern Labeling
There’s a lot of misinformation floating around TikTok and old Facebook posts about produce codes. You’ve likely seen the "hacks" telling you to avoid anything starting with an 8. Here’s the reality: GMO produce is actually pretty rare in the raw produce aisle. Most GMO crops in the United States are corn, soybeans, and sugar beets—stuff that gets processed into oils and syrups.
In the produce section, you might find GMO papaya (to resist the ringspot virus) or certain types of squash, but they aren't always labeled with an 8. In fact, new USDA "Bioengineered" labeling laws have superseded the old PLU system for GMO identification. If you really want to avoid GMOs, the 9 prefix (Organic) is your best friend, because organic standards strictly prohibit GMO seeds.
How Retailers Use This Data
Grocery stores are obsessed with these numbers. Every time a cashier types in 4065 for a green bell pepper, the store's computer system subtracts one unit from the inventory. This is why "mislabeled" produce is such a headache for managers. If a cashier rings up organic kale (96016) as regular kale (6016), the store loses money and the inventory counts get totally skewed.
From a consumer perspective, knowing the codes can save you money at the self-checkout. No, I'm not suggesting you ring up your expensive organic Honeycrisps as cheap Red Delicious apples—that’s technically fraud. But knowing that 4011 is the universal code for bananas means you don't have to scroll through five screens of "Fruit -> Yellow -> Tropical" to find your item. You just type the four digits and move on with your life.
Beyond the Sticker: What if there isn't one?
Sometimes you’ll find produce without a sticker. This usually happens with local "farm-to-table" items or bulk greens like parsley or cilantro. In these cases, the store usually has a "cheat sheet" at the register.

- Cilantro: Usually 4889.
- Parsley (Curly): Usually 4899.
- Parsley (Flat/Italian): Usually 4901.
If you're buying bagged produce, like a 3-lb bag of onions, it won't have a PLU. It has a standard UPC barcode, just like a box of cereal. PLUs are specifically for "loose" or "bulk" items sold by weight or by the piece.
Practical Tips for Your Next Trip
Next time you’re at the store, take a second to look at the sticker. If it’s a four-digit code starting with a 3 or 4, it’s conventional. If it’s five digits starting with a 9, it’s organic.
Watch the screen at checkout. Cashiers move fast. Sometimes they see a red apple and instinctively hit the code for the cheapest one, or worse, they accidentally hit the code for a more expensive variety. If you know that your Fuji apples are 4131, you can catch it if they ring them up as 4101 (Honeycrisp).
Don't fear the sticker. The adhesive used on these stickers is "food grade," and the "paper" is often a thin plastic or actual paper. While you shouldn't go out of your way to eat them, they are technically non-toxic and won't hurt you if you accidentally swallow a tiny scrap left on a peach.
Check the "Country of Origin." While not part of the PLU code itself, the sticker almost always lists where the fruit was grown. This is actually a legal requirement in many countries. If you're trying to reduce your carbon footprint, looking for a "Product of USA" or "Product of Mexico" sticker is better than buying something that flew all the way from Chile or New Zealand.
Actionable Steps for Smarter Shopping
Instead of just glancing at the numbers, try these three things on your next grocery run to master the produce aisle:
- Memorize your "Big Five": Identify the five items you buy every single week (like bananas, avocados, and lemons). Learn their codes (4011, 4046, 4033). It speeds up your checkout and makes you feel like an insider.
- Verify the Organic Prefix: If you’re paying the extra price for organic, ensure that sticker definitely starts with a 9. If the sign says organic but the sticker says 4xxx, you’re being overcharged for conventional produce.
- Inspect the Sticker Quality: A sticker that is peeling or looks "re-applied" can sometimes be a sign of mislabeling at the store level. Ensure the sticker looks original to the fruit to guarantee you're getting what you paid for.
By paying attention to these small details, you effectively turn a confusing jumble of numbers into a tool for better health and more accurate budgeting. Shopping becomes less about guessing and more about knowing exactly what’s going into your cart.
