A document sent electronically from suppliers to warehouses that provides detailed information about a pending delivery, including expected arrival time, shipment contents, quantities, SKU details, and tracking numbers. This advance notification enables warehouse teams to plan receiving operations, allocate dock doors, schedule labor, and prepare storage locations before goods arrive.
ASNs are critical for efficient warehouse operations because they transform reactive receiving into proactive planning. Instead of being surprised by deliveries, operations managers can optimize staffing levels, prioritize urgent shipments, and ensure proper equipment is available. Modern ASNs integrate directly with WMS platforms, automatically creating receiving tasks and updating inventory expectations.
For example, when a supplier ships 500 units of seasonal merchandise, their ASN alerts the warehouse two days in advance, allowing managers to reserve space in the climate-controlled zone and schedule additional staff for the expected Tuesday morning delivery.
