OUR GOAL
To provide an A-to-Z e-commerce logistics solution that would complete Amazon fulfillment network in the European Union.
Imagine a busy logistics hub in the suburbs of Paris. Thousands of pallets arrive daily. Without a standardized system, receiving goods becomes a nightmare of manual counting, opening boxes, and cross-referencing paper manifests. This is the bottleneck that kills e-commerce margins.
But in a modern, optimized supply chain, a pallet arrives, a scanner beeps once, and the Warehouse Management System (WMS) instantly knows everything: what products are on the pallet, their expiration dates, lot numbers, and exactly which customer order they fulfill.
The magic behind this efficiency isn't proprietary technology—it’s a global standard known as the SSCC (Serial Shipping Container Code). Often referred to as the "license plate" of logistics, the SSCC is the unsung hero that allows disparate systems to speak the same language, transforming chaotic warehouses into streamlined fulfillment centers.
What is the SSCC? Beyond the barcode
At its core, the SSCC is an 18-digit number used to identify a logistic unit. A "logistic unit" is any combination of trade items packaged together for storage or transport—typically a pallet, a container, or a carton.
Unlike the GTIN (Global Trade Item Number), which identifies a product (e.g., "This is a 500ml bottle of shampoo"), the SSCC identifies a specific physical shipment (e.g., "This is Pallet #982 containing 50 boxes of that shampoo, shipped on Tuesday").
Because the code is unique globally, it ensures that no two logistics units in the world share the same SSCC at the same time. This uniqueness is what earns it the "license plate" moniker. Just as a license plate links a specific car to its registration data in a government database, the SSCC links a specific pallet to the data sent in an Advance Shipping Notice (ASN).
GS1 standard connection
The SSCC is governed by GS1, the same global organization that manages the UPC and EAN barcodes found on retail products. This ensures that a pallet shipped from a factory in Shenzhen can be scanned and understood by a 3PL provider in France (like FlexLogistique) or a retailer in the USA without any data translation errors.
Anatomy of the 18-digit code
To the untrained eye, the SSCC is just a long string of numbers under a barcode. To a logistics manager, it is a structured data set. Understanding this structure is crucial for configuring label printers and WMS software correctly.
The SSCC is always 18 digits long and consists of four distinct parts:
- Extension digit (1 digit): This is a number from 0 to 9, assigned by the company creating the label. It is used to increase the capacity of the Serial Reference.
- GS1 company prefix (7-10 digits): This is the unique ID assigned to your company by GS1. It identifies who created the logistic unit (the shipper or manufacturer).
- Serial reference (6-9 digits): This is the variable part assigned by you. It identifies the specific unit. Depending on the length of your Company Prefix, this section ensures the total length remains compatible. This is the "unique" part of the license plate.
- Check digit (1 digit): The final number is calculated mathematically based on the previous 17 digits. It acts as a fail-safe; if a barcode scanner misreads a line, the check digit won't match, and the scanner will reject the read rather than outputting incorrect data.
Note: When printed on a label, the SSCC is usually encoded in the GS1-128 symbology (formerly UCC/EAN-128). You will often see (00) printed before the number in human-readable text. This (00) is the Application Identifier (AI) that tells the scanner: "The data following this is an SSCC."
GTIN vs. SSCC: Clearing the confusion
One of the most common friction points for new e-commerce sellers is distinguishing between product identification and shipment identification.
GTIN (EAN/UPC)
- Purpose: Identifies the type of product.
- Static: Every black medium t-shirt you sell has the same GTIN.
- Usage: Point of Sale (POS) scanning and inventory listing.
SSCC
- Purpose: Identifies a specific delivery unit.
- Dynamic: Every pallet of t-shirts you ship gets a brand new, unique SSCC.
- Usage: Shipping, receiving, cross-docking, and tracking.
Think of it this way: The GTIN is the model of the car (e.g., Ford Mustang). The SSCC is the license plate on a specific Ford Mustang. You can have thousands of Mustangs, but each one has a unique plate.
SSCC and the ASN (Advance Shipping Notice)
The SSCC is useless on its own. A license plate means nothing if there is no database to look it up in. In logistics, that database is the ASN (Advance Shipping Notice), often transmitted via EDI (Electronic Data Interchange) code 856.
This is the workflow that separates amateur operations from professional logistics:
- Pack: The supplier stacks 50 boxes onto a pallet.
- Association: The supplier’s WMS records exactly which items (GTINs, quantities, batch numbers) are on that pallet.
- Label: The system generates a unique SSCC label and applies it to the pallet.
- Data transfer: The supplier sends an ASN (EDI 856) to the receiver (e.g., the fulfillment center). This digital message says: "SSCC #12345 is coming, and it contains exactly these 50 items."
- Receipt: When the truck arrives at the warehouse, the receiver scans the SSCC barcode.
- Match: The receiver's WMS instantly pulls up the data from the ASN. They don't need to count the boxes. They scan one code, and the system automatically receives all 50 items into inventory.
Why this matters for e-commerce
Without this link, receiving inventory ("dock-to-stock" time) can take days. With SSCC and ASN, it takes minutes. For an e-commerce business, this means your stock is available for sale on your website faster, improving cash flow and customer satisfaction.
Why warehouses and 3PLs demand SSCC
If you are outsourcing your logistics or shipping to major retailers (like Amazon, Carrefour, or Walmart), you are likely required to use SSCC labels. Here is why logistics providers prioritize shipments that use them.
1. Speed and "one-scan" receiving
Manual receiving is prone to human error. A worker might count 49 boxes instead of 50. SSCC allows for automated receiving. If the ASN says there are 50, the system books 50. Disputes are handled digitally, not on the warehouse floor.
2. Traceability and recall management
In industries like food, cosmetics, or pharmaceuticals, traceability is legal compliance, not a luxury. If a specific batch of face cream is recalled, the SSCC allows the warehouse to locate exactly which pallet that batch is sitting on, or exactly which customer order it was shipped in.
3. Enabling cross-docking
Cross-docking is a logistics strategy where incoming materials are unloaded and directly reloaded onto outbound trucks with little to no storage in between. This is impossible without SSCC. The scanner reads the label, sees the final destination embedded in the associated data, and directs the forklift driver to the outbound bay immediately.
Best practices for label placement and printing
Having a valid number is only half the battle; the barcode must be readable. Logistics environments are harsh—conveyor belts, forklifts, and dust can damage labels.
GS1-128 logistic label standard
The SSCC is typically part of a larger standard label that consists of three sections:
- Free format information (Top): Company name, destination address.
- Human readable text (Middle): Details about contents, expiration dates, and the text version of the SSCC.
- Barcodes (Bottom): The machine-readable SSCC.
Placement rules
- Pallets: The label should be placed on a vertical side, not the top. For full pallets, GS1 recommends placing labels on two adjacent sides (e.g., the short side and the long side) so the forklift driver can scan it from any angle of approach.
- Height: Ideally, the barcodes should be between 400mm and 800mm from the base of the pallet.
- Quality: Use thermal transfer printing for durability. Direct thermal labels can fade if exposed to heat or sunlight in a truck, rendering the SSCC unreadable.
Common mistakes that disrupt the supply chain
Even experienced shippers make errors with SSCCs. Avoiding these keeps your freight moving.
- Reusing SSCCs too soon: According to GS1 standards, an SSCC should not be reused for at least 12 months. Ideally, never reuse them. A duplicate SSCC in a global supply chain causes data collisions that require manual IT intervention to fix.
- Missing ASN data: Shipping a pallet with an SSCC label but failing to send the electronic ASN is called "Blind Receiving." The warehouse scans the code, but "no record is found." The shipment then sits in a holding area until paperwork is manually emailed, causing significant delays.
- Poor barcode quiet zones: The "quiet zone" is the white space on the left and right edges of the barcode. If you print text or lines too close to the barcode, scanners cannot distinguish where the code starts and ends.
Is SSCC mandatory for selling online?
Technically, you can run a small warehouse without SSCCs. You can rely on SKU labels and manual counting. However, as you scale, the lack of SSCC becomes a "growth ceiling."
If you ship to Amazon FBA, you are already using a variation of this concept (the FBA Box ID). If you begin selling wholesale to big-box retailers, they will issue a "chargeback" (a fine) for every shipment that arrives without a compliant SSCC label.
Furthermore, if you partner with a professional 3PL (Third Party Logistics) provider, providing SSCC-labeled inventory makes you a "preferred client." It means your goods are processed faster during peak seasons (like Black Friday) because your shipments are easier to handle than those of a client sending unlabelled, chaotic boxes.
Turning compliance into competitive advantage
Many businesses view the implementation of SSCC as a burden—a technical hoop to jump through to satisfy a retailer or a logistics partner. This is a limited view.
Implementing SSCC is a step toward digitizing your inventory. It creates a granular level of visibility that allows you to track goods not just by "what" they are, but by "where" and "when" they moved. It reduces shrinkage (lost inventory), accelerates inventory turnover, and minimizes the labor cost per unit shipped.
For a modern brand, the logistics chain is part of the customer experience. The faster a warehouse can receive your goods via SSCC, the faster those goods are available on your website. In the race for delivery speed, the humble 18-digit code is one of the most powerful tools in your arsenal.
