Why I’ll Never Buy Another Fruit or Vegetable Without the “Codes Rule” Again

Across the country, self-checkout has become the new normal. What used to be reserved for in-and-out trips for a handful of groceries (I still remember when it used to be exclusively 15 items or less), these stand-alone kiosks are now the default option for many, including shoppers with carts filled to the brim. The technology has gotten noticeably smoother in recent years, and certain retailers (eh hem, Aldi) even plaster oversized barcodes across packaged items to speed things up even further. 

One section you don’t find these giant time-savers, though? Produce. Specifically the loose fruit and vegetables, like apples, bananas, broccoli, etc.

I buy a lot of produce, so I know firsthand how tricky it is to scan each item and, when that fails, then type in the name of said item on the screen because the machine didn’t register the notoriously small barcode on my avocado (fun times!). Recently I picked up a new tip from our senior groceries editor, Mara, that eliminates loads of produce barcode scanning and makes self-checkout feel like an express lane. The trick is to memorize the Price Lookup (PLU) codes (or produce codes) on your favorite produce items

What Exactly Are PLU Codes?

You know that small sticker with the tiny barcode on an avocado or apple? That barcode typically also has a series of four or five-digit numbers above (or below) it. That’s the PLU code. First introduced in the 1990s by supermarkets across the country (and even globally), the goal of these codes was to make checkout and inventory control faster and more efficient. 

Four-digit codes are the most common and used for conventional produce, while five-digit produce codes are generally reserved for organic produce. To make it even more streamlined, organic produce PLU codes are typically the conventional four-digit code, with a 9 in the front. For example, a banana’s conventional code is 4011, while organic bananas are 94011

Why You Should Memorize PLU Codes for Your Favorite Items

Since their standardization almost 30 years ago, the sticker codes seen on fruit and vegetables have pretty much become consistent across grocery stores. That means you can memorize the four or five-digit codes on the produce items you buy most often (bananas, blueberries, lettuce, etc), and apply them at practically any grocery store. So instead of finnicking with the (often lagging) touch screen or attempting to scan the miniature code, you can simply type in that four-digit number you now know by heart to make checkout much faster.

A Few PLU Codes to Keep in Mind for Your Next Grocery Shop

For most of us, it’s unrealistic to memorize an entire grocery store’s worth of product codes. I recommend you start small and memorize a handful of codes for your go-to produce picks; it’ll save you time and hassle. You can search for specific codes on the International Federation for Produce Standards (IFPS). In the meantime, here are a few of my favorites to get you started.

  • Conventional Bananas: 4011
  • Organic Bananas: 94011
  • Conventional Blueberries: 4240
  • Organic Blueberries: 94240
  • Conventional Cilantro: 4889
  • Organic Cilantro: 94889
  • Conventional Lettuce (Green Leaf): 4061
  • Organic Lettuce (Green Leaf): 94061
  • Conventional Ginger: 4612
  • Organic Ginger: 94612
  • Conventional Small Hass Avocado: 4046
  • Organic Small Hass Avocado: 94046
