GS1-128 and SSCC for Inbound Shipments Across Retailers
Many retailers use the same inbound receiving model described in the Amazon-specific article. Amazon is a common example, but the underlying process is broader than one trading partner. Retailers such as Fastenal use the same GS1-based approach to connect a physical carton label to the shipment data sent in the ASN.
For Pacejet implementations, this matters because you can build one core SSCC and ASN process that supports multiple retailers. Most retailer differences appear in label format, print requirements, and compliance details, not in the underlying carton identification model.
The Shared Industry Model
The standard inbound model uses a GS1-128 barcode with an SSCC to identify a carton or pallet during receiving. That same SSCC is also sent in the ASN, typically through EDI 856, before the shipment arrives. When the retailer scans the barcode, the receiving system extracts the SSCC and matches it to the ASN record for that carton.
This is often called a license plate receiving model because the barcode acts as the shipment unit’s unique identifier. A single scan can retrieve the expected shipment data without requiring the receiver to open the carton or scan each item individually.
The core elements stay the same across many retailers:
SSCC-18: an 18-digit identifier for a carton or pallet. Each SSCC must be unique.
ASN: the advance ship notice that includes the SSCC for each shipping unit.
GS1-128 barcode: the barcode format used to encode the SSCC.
Receiving scan: the process that reads the barcode, extracts the SSCC, and matches it to the ASN.
In most implementations, the SSCC barcode encodes:
FNC1 + 00 + SSCC
In this structure, FNC1 tells the scanner to parse the barcode as GS1 data, 00 is the application identifier for SSCC, and the remaining 18 digits are the carton or pallet identifier.
How the Receiving Process Works
The receiving workflow is consistent across retailers that use GS1 carton license plates. The shipper assigns a unique SSCC to each carton, sends that SSCC in the ASN, and prints the same SSCC in a GS1-128 barcode on the label. At receiving, the retailer scans the barcode and uses the extracted SSCC to find the carton record in the ASN.
When the barcode data and ASN data match, the shipment can move through receiving with little or no manual intervention. When they do not match, the receiving team may need to research the carton manually, which can delay processing and create compliance issues.
Warning: The SSCC in the barcode and the SSCC in the ASN must match exactly. A correct label format does not help if the 18-digit value differs between the printed barcode and the shipment data.
Fastenal as a Comparison Example
Fastenal follows the same general pattern as Amazon. The carton label uses a GS1-128 barcode with the SSCC, and the ASN includes the same SSCC so the receiving system can match the physical shipment to the electronic record.
The shared requirements include:
GS1-128 barcode: uses application identifier
00for the SSCCSSCC in the ASN: includes the same SSCC sent ahead of shipment
Scan-based receiving: uses the scanned SSCC to retrieve shipment data and complete receiving
The differences are usually operational rather than structural. Fastenal may define label format and print expectations more explicitly, such as label size, label zones, barcode quality, and placement on cartons or pallets. Amazon guidance is often more focused on whether the scanned barcode data matches the ASN data and less focused on publicly documented layout standards.
That means the receiving logic stays the same even when the compliance details differ by retailer.
Why Retailers Use This Model
Retailers use SSCC-based receiving because it scales well in high-volume distribution environments. The barcode gives each carton a unique identity that the receiving system can match to shipment data in one step.
With a valid SSCC scan, the retailer can retrieve:
Purchase order information: the order tied to the shipment
Expected contents: what the carton is supposed to contain
Quantities: how many units are expected
This reduces the need to open cartons during receiving or scan individual items just to confirm basic shipment data. As a result, retailers can reduce labor, shorten receiving time, and lower the risk of manual data-entry errors.
What This Means for Pacejet
For Pacejet, the goal is to build one reliable core process that can support many retailer programs. You do not need a separate underlying SSCC strategy for each customer. The foundation should be consistent across implementations.
The core Pacejet solution should support:
SSCC generation: create unique, non-repeating SSCC values
SSCC persistence: keep the same SSCC tied to the carton across label generation and ASN output
Barcode encoding: encode the carton barcode as
FNC1 + 00 + SSCCValidation: confirm that the SSCC printed on the label matches the SSCC sent in the ASN
Retailer-specific requirements should be layered on top of that core process. These usually include label templates, print specifications, placement guidance, and any customer-specific compliance rules.
Note: When troubleshooting retailer compliance issues, start with the shared data model first. Confirm the SSCC is unique, correctly encoded, and identical in both the label and the ASN before focusing on label layout or print quality.
Key Takeaway
Amazon is a visible example of a much broader industry pattern. Fastenal and many other retailers use the same GS1-128, SSCC, and ASN matching model for inbound shipments.
If Pacejet generates one SSCC per carton, encodes that value in the GS1-128 barcode, and sends the same value in the ASN, you have the foundation needed for multi-retailer inbound compliance. From there, most customer-specific work is about label format and execution rather than a different data model.
