ASNs are often used in conjunction with SSCC which stands for Serial Shipping Container Codes, to further improve the efficiency of the receipt and reconciliation process further. SSCCs are used to identify and track logistics units, which simply refer to items that have been packaged together for storage or transportation, such as outer cases, pallets, or entire shipments. SSCC labels can be scanned and matched against the Advanced Shipping Notice to reconcile what is received against what the buyer was told would be sent.
