PLU Code Definition
A PLU code (Price Look-Up code) is a standardized 4 or 5-digit number assigned to a specific type of fresh produce. When a cashier or self-checkout scanner reads the code, it tells the point-of-sale system exactly what the item is and how to price it.
PLU codes are assigned and managed by the International Federation for Produce Standards (IFPS), a global organization that maintains the universal PLU code database used by retailers worldwide.
The system has been in use since the 1990s and is now the global standard for fresh produce identification at retail checkout.
PLU Code vs. PLU Label — What's the Difference?
These terms are often used interchangeably, but they refer to different things:
- •PLU code — the number itself (e.g., 4011 for bananas). A standardized identifier assigned by IFPS.
- •PLU label — the physical adhesive sticker applied to the produce that displays the PLU code, and optionally a brand logo, barcode, or other information.
How PLU Codes Are Structured
Conventional produce (most common)
Certified organic produce
GMO produce (rarely used)
