What is an Amazon LPN Number?

An Amazon LPN (License Plate Number) is a unique identifier assigned to individual units of inventory, such as pallets, cartons, or totes, upon arrival at a warehouse or distribution center. This identifier is crucial for efficiently tracking and managing inventory, especially in the returns process.

Key Points About LPN Numbers

  1. Tracking Inventory: LPNs help track inventory and shipments as they move through the supply chain. This is particularly important for returns, as it ensures that returned items are accurately accounted for and processed.
  2. Efficient Identification and Processing: LPNs allow warehouses to efficiently identify, locate, and process inventory. When a returned item arrives, its LPN is scanned to quickly retrieve its details, facilitating swift and accurate processing.
  3. Data Generation: LPNs are scanned at various points in the warehouse workflow—during receiving, putaway, picking, packing, and shipping. This generates valuable data on the item’s movement, which can be used to optimize inventory management and streamline operations.
  4. Consistency in Tracking: The LPN stays with the goods as long as they remain in their original packaging. If the items are repackaged, a new LPN may be assigned, ensuring continuous and accurate tracking.

The Role of LPNs in Returns Management

  • Streamlined Returns Process: When items are returned to the warehouse, their LPNs provide a straightforward way to identify and track them. This helps in quickly processing returns, restocking items, or addressing any issues with the returned goods.
  • Enhanced Accuracy: Using LPNs reduces the risk of errors in handling returned items. Each returned item can be accurately tracked and matched with its original order, ensuring correct processing and minimizing discrepancies.
  • Inventory Insights: The data generated by scanning LPNs at various stages provides insights into the returns process. This information can help identify common reasons for returns, assess the condition of returned items, and make data-driven decisions to improve product quality and customer satisfaction.


In summary, an LPN, or License Plate Number, is a unique ID assigned to inventory units to track their movement and status throughout the supply chain. This is especially valuable in managing returns, as it ensures efficient identification, accurate processing, and comprehensive tracking of returned items.
