Comprehensive Definition
The EAN (now integrated into the global GTIN standard) is the most widely used barcode system in the world for identifying consumer products in retail. The most common format is EAN-13, composed of thirteen digits that identify the country of origin, the manufacturing company, and the specific product.
Structure of an EAN-13 Code
Prefixes (3 digits)
Identify the country's GS1 organization (e.g., 560 for Portugal).
Company Code
Assigned by GS1 to the brand owner of the product.
Article Reference
Defined by the company itself for each SKU.
Check Digit
A final digit mathematically calculated to ensure the scanner reading is correct.
Importance of EAN for WMS
Without standardized coding like EAN, automated warehouse management would be impossible. In the WMS, EAN enables:
Blind and Fast Reception
By reading the EAN code at reception, the system immediately identifies the product, its dimensions, and characteristics, without the need for manual data entry.
Elimination of Picking Errors
The WMS requires the operator to scan the product's EAN before placing it in the shipping box. If the code doesn't match the order, the system blocks the task, ensuring an error rate close to zero.
Interoperability
Allows manufacturers, distributors, and retailers to speak the same logistics "language" across Europe.
