Advance Shipping Notice (EDI 856): What Retailers Expect

What is an advance shipping notice?

An advance shipping notice (ASN), commonly transmitted as EDI 856, is an electronic shipment record sent before freight arrives at a retailer or distribution center. Field-level receiving data shows that DCs using scan-based receiving can cut unload-to-receipt time by 30-50% when ASN carton IDs match physical labels, while missing or mismatched ASNs push freight into manual exception lanes.

Cost structure / standard tiers

ASN costs usually appear as direct chargebacks or indirect receiving delays.

ASN Issue	Typical Cost Range	Receiving Impact
Missing ASN	$100-$500/shipment	Manual receiving required
Late ASN	$50-$250/PO	Dock appointment may be held or delayed
Carton count mismatch	$25-$100/PO plus audit time	Quantity reconciliation needed
Invalid SSCC/carton IDs	$5-$25/carton	Scan receiving fails

Large retailers often enforce ASN rules per purchase order, while 3PLs may bill manual receiving labor separately.

Risk mitigation / operational guidance

Send the ASN after final cartonization, not before pick-pack is complete, because early ASNs often diverge from physical cartons. Validate PO, SKU, carton count, carrier, PRO/tracking number, and ship date before transmission. For EDI retailers, run test ASNs before the first live shipment and confirm the retailer can parse every segment. If using a 3PL, assign ownership for ASN release timing so the warehouse and seller do not both assume the other party sent it.
