Understanding Barcode Numbers: A Step-by-Step Explanation
Barcode numbers are essential tools for product identification and tracking in modern business operations. They represent data in a visual format that can be quickly scanned and interpreted by machines. The importance of barcode number lies in their ability to streamline inventory management, enhance product traceability, and facilitate efficient supply chain operations.
Types of Barcode Numbers
UPC Barcodes
UPC (Universal Product Code) barcodes are widely used in the retail industry, particularly in North America. They consist of 12 digits and are designed to uniquely identify products. The structure of a UPC barcode includes a manufacturer prefix, an item reference, and a check digit.
Common Uses: UPC barcodes are commonly found on consumer goods in supermarkets, convenience stores, and other retail environments.
EAN Barcodes
EAN (European Article Number) barcodes are similar to UPC barcodes but are primarily used outside of North America. They come in two main formats: EAN-13, which consists of 13 digits, and EAN-8, which has 8 digits for smaller items.
Applications: EAN barcodes are used in international trade, enabling seamless product identification across different countries and regions.
ISBN Barcodes
ISBN (International Standard Book Number) barcodes are specifically used in the publishing industry. They contain 13 digits and are used to uniquely identify books, facilitating their distribution and sale.
Role: ISBN barcodes help publishers, retailers, and libraries manage book inventories and sales efficiently.

Company Prefix
The company prefix is a unique identifier assigned to each organization by GS1. It forms part of the barcode number and helps distinguish products from different companies.
