ASN (Advance Ship Notice)
A document sent by a supplier to a buyer ahead of a shipment, detailing what is being shipped, how it is packed, and when it will arrive.
In practice
ASNs are usually X12 856 in the US or EDIFACT DESADV in Europe. They include hierarchical pack structure, SSCC barcodes, and shipment-level data.
Why it matters
Late, missing, or incorrect ASNs are one of the most common chargeback triggers.
