Pallet & Case Labeling: ITF-14 vs GS1-128

Outer case and pallet labeling requires choosing between ITF-14 for simple identification and GS1-128 for detailed supply chain data. Many logistics operations use both, leveraging each symbology's strengths.

When to Use ITF-14

ITF-14 is the right choice for:

• Simple case identification: GS1 Standards & Identifiers">gtin-14/" class="glossary-term-link" data-term="GTIN-14" data-definition="14-digit identifier for ITF-14 barcodes on cases and pallets." data-category="GS1 Standards & Identifiers">GTIN-14 only (indicator + EAN-13, the global standard." data-category="GS1 Standards & Identifiers">GTIN-13)
• Corrugated board printing: Wide bars tolerate ink spread
• Flexographic printing: Can be printed directly on the carton
• Cost-sensitive applications: Simpler, cheaper printing

When to Use GS1-128

GS1-128 is required when:

• SSCC tracking: Serial shipping container codes for logistics
• Batch/lot data: Traceability information on the label
• Expiration dates: Date data encoded in the barcode
• Trading partner requirements: Most major retailers mandate GS1-128

Side-by-Side Comparison

Dual Labeling

Many supply chains use both:

• ITF-14 printed directly on the case: For basic product identification
• GS1-128 label applied to the case: For SSCC, batch, and date data

The ITF-14 identifies what is in the case. The GS1-128 label tracks the specific case through the supply chain.

Label Placement Rules

GS1 specifies label placement for maximum scan efficiency:

• Cases: Label on the long side, within the bottom right third
• Pallets: Labels on two adjacent sides, 400-800mm from ground
• Avoid: Labels on the top (hidden when stacked), directly on seams or flaps

Printing Considerations

For direct printing on corrugated:

• Use ITF-14 with bearer bars
• Apply bar-width-reduction/" class="glossary-term-link" data-term="bar width reduction" data-definition="Narrowing bars in prepress to compensate for ink spread." data-category="Printing & Quality">bar width reduction (BWR) to compensate for ink spread
• Test print quality on actual production corrugated stock
• Verify with a barcode verifier after printing

For labels on cases:

• Use GS1-128 on label stock
• Thermal transfer printing for durability
• Apply labels with automated applicators for consistency
• Verify print quality inline during production
