The UPC-EAN barcode is a widely used symbology for retail product identification. It is a lineal barcode that consists of a series of black bars and white spaces of varying widths, representing numerical data. The UPC-EAN barcode is a superset of the original UPC (Universal Product Code) system, incorporating the EAN (European Article Number) standards. This integration allows for global compatibility and a larger capacity for product information.

There are two primary types of UPC-EAN barcodes: UPC-A and EAN-13. UPC-A is a 12-digit code commonly used in North America, while EAN-13 is a 13-digit code prevalent internationally. The additional digit in EAN-13 is a national code. Both systems encode product information such as manufacturer identification and item number. The last digit in both UPC-A and EAN-13 is a check digit, calculated using a specific algorithm to ensure data accuracy during scanning.

The structure of a UPC-EAN barcode includes a quiet zone on either side, a system character, manufacturer code, product code, and the check digit. The system character indicates the type of number system being used. These barcodes are essential for inventory management, point-of-sale transactions, and supply chain tracking, enabling efficient and error-free data capture in retail environments worldwide.
