Introduction
In the global marketplace, efficient product identification is vital for smooth transactions between manufacturers, retailers, and consumers. Standard product codes like EAN (European Article Number), GTIN (Global Trade Item Number), and UPC (Universal Product Code) play a crucial role in this ecosystem. While these codes share the common goal of uniquely identifying products, they differ in structure, geographic relevance, and application. Understanding these differences helps businesses optimize supply chains, streamline inventory management, and ensure international compatibility.
What is GTIN?
The Global Trade Item Number (GTIN) is an internationally recognized system for product identification. GTINs can range from 8 to 14 digits, accommodating diverse product types—from single items to bundles and pallets. Serving as the overarching identification system, GTIN includes both EAN and UPC formats. Governed by GS1 standards, GTIN ensures global consistency in product tracking, inventory management, and sales reporting.

What is EAN?
The European Article Number (EAN) is typically a 13-digit code (with an 8-digit variant for smaller items) used predominantly outside North America. EAN codes are integral to European and international retail operations, facilitating inventory management, sales tracking, and cross-border trade. They are structured to include a country prefix, manufacturer code, product code, and a check digit for error detection.
What is UPC?
The Universal Product Code (UPC) is a 12-digit code primarily used in North America. It consists of a company prefix (identifying the manufacturer) and an item reference number (identifying the product). The final digit serves as a check digit. UPC is widely used in retail point-of-sale systems, ensuring fast, accurate transactions for consumers and retailers alike.
Structural Differences
| Code | Length | Components | Key Feature |
| GTIN | 8, 12, 13, 14 | Encapsulates EAN and UPC formats | Flexible global identifier |
| EAN | 13 (or 8) | Country code + Manufacturer code + Product code + Check digit | International standard outside North America |
| UPC | 12 | Company prefix + Product code + Check digit | Standard in North American retail |
