The Advance Shipping Notice (ASN) is an electronic message transmitted through EDI to notify the consignee of pending deliveries. The CLT dispatch/tracking framework identifies the ASN as a critical communication tool containing shipment details such as contents, quantities, carrier, and seal numbers. It allows the receiving facility to schedule dock appointments, allocate labor, and prepare for verification. Proof of Delivery confirms completion, not notification; Air Waybill applies to air freight; the consignee is the receiving entity. The ASN thus bridges outbound and inbound logistics, improving efficiency and data accuracy throughout the supply chain.
