Definition & Explanation

The Universal Product Code (UPC) is a standardized 12-digit barcode used by retailers, distribution centers, and logistics operators to automate product identification throughout the supply chain. Its structure combines a GS1-assigned manufacturer identifier with an item reference number, enabling reliable scanning at checkout points, within warehouse management systems, and across transport operations. The UPC is closely related to—but distinct from—the EAN (European Article Number, or GTIN-13): both are part of the global GS1 system and are technically interoperable, but the UPC carries 12 digits and remains the dominant format in North America. For international trade, the broader GTIN framework is increasingly preferred as it encompasses both formats under a single standard.
