A Product Code is a unique identifier assigned to a specific item or product. It helps businesses and consumers easily track, manage, and differentiate products in inventory systems. Common types of product codes include UPC (Universal Product Code) and SKU (Stock Keeping Unit), which are used in retail and e-commerce. These codes are essential for various functions, such as pricing, sales tracking, and inventory management. By using product codes, companies can streamline their operations and improve customer service, ensuring that the right products are available when needed.
