Definition

SSCC (Serial Shipping Container Code) is an 18-digit GS1 identifier marking a unique concrete logistics unit: a specific pallet shipped on a specific date. It contains: extension digit (1), GS1 company prefix, serial number assigned by the supplier, check digit.

Role in the logistics chain

SSCC is the glue between the physical pallet label and the EDI DESADV (ASN) message. The retailer scans the GS1-128 label at receipt, identifies the SSCC, finds it in the already-received ASN, validates content automatically.

Common errors

SSCC reused within <12 months → retailer confusion, penalty

SSCC with invalid check digit → auto rejection

ASN sent before the SSCC pallet physically exists → mismatch at receipt

Label with SSCC but no WMS association → orphan units
