ASN’s are often used in conjunction with SSCC's which stands for Serial Shipping Container Codes to further improve the efficiency of the receipt and reconciliation process. SSCC's  are used to identify and track logistics unit, which simply means items which have been packaged together for storage or transportation, for example 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.
