A unique alphanumeric identifier assigned to each distinct product variant in a warehouse’s inventory system, enabling precise tracking and management of individual items. SKUs differentiate products by specific attributes such as size, color, model, or packaging configuration, ensuring accurate inventory control even for similar products.
This granular identification system is fundamental to warehouse efficiency, enabling accurate pick lists, cycle counts, and inventory replenishment. SKUs streamline order fulfillment by eliminating confusion between product variants and provide the data foundation for analytics like turnover rates and demand forecasting.
For example, a single smartphone model might have multiple SKUs: “IPH14-128-BLK” for a 128GB black iPhone 14, “IPH14-128-WHT” for the white version, and “IPH14-256-BLK” for the 256GB black model. This precise categorization ensures warehouse staff pick the exact item customers ordered while maintaining accurate stock levels across all product variations.
