Whether you're a manufacturer, distributor, retailer, or logistics provider, implementing SSCC barcodes can significantly enhance your shipping operations and compliance with trading partner requirements.

This comprehensive guide will walk you through everything you need to know about generating and implementing GS1-128 SSCC barcodes for your pallet labeling needs. From understanding the fundamental structure of SSCC codes to creating compliant labels and integrating them into your workflow, we'll cover all the essential aspects to help you successfully implement this critical supply chain technology.

What is a GS1-128 SSCC Barcode?

GS1-128 SSCC barcode is a standardized barcode format specifically designed for logistics and supply chain applications. Unlike retail barcodes such as UPC-A or EAN-13, which identify individual products, SSCC barcodes identify logistics units - containers that can hold multiple items, most commonly pallets.

Key Components of GS1-128 SSCC

The GS1-128 barcode symbolology (formerly known as UCC/EAN-128) is an application standard of the Code 128 barcode symbology. What makes GS1-128 special is its ability to encode GS1 Application Identifiers (AIs) that provide standardized meanings to the data encoded within the barcode.

When used for SSCC, the GS1-128 barcode contains:

Application Identifier (00) - A two-digit prefix that indicates the data that follows is an SSCC
SSCC Number - An 18-digit number that uniquely identifies the logistics unit

Understanding the SSCC Structure

The 18-digit SSCC number follows a specific structure:

Extension Digit (1 digit) - Used for increasing the capacity of the SSCC
GS1 Company Prefix (7-10 digits) - Assigned by GS1 to identify your company
Serial Reference (6-9 digits) - Assigned by your company to uniquely identify the logistics unit
Check Digit (1 digit) - Calculated based on the previous digits to ensure data integrity

For example, an SSCC might look like: (00) 1 8012345 000000001 8

Where:

(00) is the Application Identifier
1 is the Extension Digit
8012345 is the GS1 Company Prefix
000000001 is the Serial Reference
8 is the Check Digit

Why Use GS1-128 SSCC Barcodes for Pallet Labeling?

Implementing GS1-128 SSCC barcodes for your pallet labeling offers numerous advantages that impact your entire supply chain operation:

Benefits of Using SSCC Barcodes

Global Unique Identification - Each SSCC is globally unique, ensuring no two pallets anywhere in the world have the same identifier
Supply Chain Visibility - Track pallets through every step of the supply chain, from manufacturing to retail
Improved Efficiency - Streamline receiving and shipping processes with automated scanning
Error Reduction - Minimize manual data entry errors that can lead to shipping mistakes
Regulatory Compliance - Meet industry and customer requirements for standardized labeling
Enhanced Traceability - Support product recalls and authenticate shipments with precision
Cross-Border Compatibility - Use internationally recognized standards for global shipping
ASN (Advanced Shipping Notice) Support - Enable electronic data interchange with trading partners

Many major retailers and distributors now require suppliers to use SSCC barcodes on pallets. Companies like Walmart, Target, Amazon, and most grocery chains have specific requirements for SSCC implementation in their supplier guidelines.

How to Generate GS1-128 SSCC Barcodes

Generating correct and compliant GS1-128 SSCC barcodes involves several steps. Here's a comprehensive guide to help you through the process:

Prerequisites for SSCC Generation

Before you can generate SSCC barcodes, you'll need:

GS1 Company Prefix - Obtain this from your local GS1 organization by becoming a member
Understanding of SSCC Structure - Know how to format your SSCC based on your prefix length
Barcode Generation Tool - Software or online service capable of creating GS1-128 barcodes
Printing Capability - Appropriate printers and materials for producing durable labels

Step-by-Step Process to Generate SSCC Barcodes

Step 1: Determine Your SSCC Structure

Based on your GS1 Company Prefix length, determine how many digits you have available for your Serial Reference:

7-digit prefix = 9-digit serial reference
8-digit prefix = 8-digit serial reference
9-digit prefix = 7-digit serial reference
10-digit prefix = 6-digit serial reference

Step 2: Choose an Extension Digit

The extension digit (first digit after the AI) can be any number from 0-9. Many companies simply use 0 or 1, but you can use this digit strategically to differentiate between types of logistics units or facilities.

Step 3: Create a Serial Reference Numbering System

Develop a system for assigning serial reference numbers to your logistics units. This could be:

Sequential numbering (e.g., 000000001, 000000002, etc.)
Date-based numbering (e.g., YYMMDDNNN where NNN is a daily sequence)
Location-based numbering (where certain ranges are assigned to specific warehouses)

Ensure your system avoids duplicating numbers within a reasonable timeframe (typically at least one year).

Step 4: Calculate the Check Digit

The check digit is calculated using the standard GS1 algorithm:

Starting from the right of the 17 digits (Extension Digit + GS1 Company Prefix + Serial Reference), assign alternating weights of 3 and 1. The rightmost digit gets a weight of 3, the next one 1, and so on.
Multiply each of the 17 digits by its assigned weight.
Sum all these products.
Subtract this sum from the next highest (or equal) multiple of 10. The result is the check digit. (If the sum is already a multiple of 10, the check digit is 0).

For example, for the 17 digits 18012345000000001:

Weights (right to left): 3,1,3,1,3,1,3,1,3,1,3,1,3,1,3,1,3

Products: 3,0,0,0,0,0,0,0,0,0,15,4,9,2,3,0,24

Sum of products: 3+0+0+0+0+0+0+0+0+0+15+4+9+2+3+0+24 = 60

Next highest or equal multiple of 10: 60

Check digit: 60 - 60 = 0

Many online calculators and barcode generation tools will perform this calculation automatically.

Step 5: Combine All Elements

Put together your complete SSCC: (00) + Extension Digit + GS1 Company Prefix + Serial Reference + Check Digit

Step 6: Generate the Barcode

Use a barcode generator that supports GS1-128 format. When entering the data:

Include the Application Identifier (00). Some tools may require it with parentheses, others without.
Ensure the software correctly generates FNC1 characters as required by the GS1-128 standard. (FNC1 is typically implicit when using AI (00)).
Verify the barcode meets the minimum size requirements (see below).

Technical Specifications for GS1-128 SSCC Barcodes

To ensure your barcodes scan reliably throughout the supply chain, they must meet specific technical requirements:

Symbol Dimensions

X-dimension (narrow bar width): 0.495mm - 1.016mm (19.5 - 40 mils)
Minimum bar height: 31.75mm (1.25 inches)
Quiet zones: Minimum 10X on each side (where X is the X-dimension)

Print Quality

ISO/IEC print quality grade: Minimum grade C (1.5) at point of use
Verification recommendation: Grade B (2.5) at point of production

Creating Compliant GS1 Logistics Labels

SSCC barcodes are typically part of a larger standardized logistics label known as the GS1 Logistics Label. Here's how to create a compliant label:

GS1 Logistics Label Structure

The standard GS1 logistics label is divided into three sections:

Top Section (Carrier Information) - Optional information for carriers (e.g., postal codes, routing codes)
Middle Section (Customer Information) - Information for customers (e.g., PO number, product details)
Bottom Section (Transport Information) - Information for transporters, including the SSCC barcode

Required Elements on GS1 Logistics Labels

At minimum, a GS1 logistics label should include:

SSCC Barcode - The GS1-128 barcode encoding the SSCC
Human-Readable SSCC - The SSCC number printed in text form
AI Identifier - The Application Identifier (00) in parentheses should be part of the human-readable text if not encoded directly by the generator.

Additional elements commonly included:

Content Description - What the pallet contains
Count Information - Number of units/cases
Weight Information - Gross weight of the logistics unit
Date Information - Production or ship date
Batch/Lot Number - For traceability
Destination Information - Where the pallet is being shipped

Label Placement Standards

For maximum visibility and scanning efficiency:

Height: Place labels between 400mm and 800mm from the base of the unit
Sides: Place labels on two adjacent sides of the pallet (when possible)
Orientation: Barcodes should be printed in "picket fence" orientation (bars perpendicular to the base)
Protection: Consider using protective sleeves or covers in harsh environments

SSCC vs. Other Barcode Standards

Understanding how SSCC compares to other barcode standards can help you determine the right solution for your needs:

SSCC vs. License Plate

"License Plate" is a general term for a unique identifier assigned to logistics units. SSCC is the standardized GS1 implementation of the license plate concept. While proprietary license plate systems may work within closed systems, the SSCC provides global interoperability.

SSCC vs. ITF-14

While both can be used in logistics, ITF-14 typically identifies product types (GTINs for cases/cartons), while SSCC identifies specific logistics units. ITF-14 uses a different symbology with thicker bars, making it more suitable for direct printing on corrugated surfaces.

SSCC vs. Data Matrix

Data Matrix is a 2D barcode with high data density, often used for small item marking. SSCC uses the linear GS1-128 symbology, which is more suitable for logistics scanning environments where longer-range scanning is required.

SSCC vs. QR Codes

While QR codes can encode SSCCs, the GS1-128 linear format remains the standard for logistics labels due to compatibility with existing scanning infrastructure and readability at a distance.

Future Trends in Logistics Labeling and Tracking

The world of logistics identification continues to evolve. Here are some emerging trends to watch:

Digital Link and QR Integration

GS1 Digital Link enables the encoding of SSCC and other identifiers in QR codes that can be linked directly to online information, bridging the physical and digital worlds.

RFID and SSCC Integration

Some companies are implementing dual-technology solutions with both SSCC barcodes and RFID tags, providing redundancy and enabling both manual and automated identification.

Blockchain Integration

SSCCs are beginning to be integrated with blockchain solutions for enhanced supply chain transparency and verification.

Environmental Sustainability

New label materials and minimalist designs are emerging to reduce environmental impact while maintaining functionality.

FAQs about GS1-128 SSCC Barcodes
