ITF-14 Barcode Generator: Supply Chain Packaging Identification

ITF-14 is the standard barcode format used for shipping containers and outer packaging in the global supply chain. Our free online ITF-14 generator allows you to create GS1-compliant barcodes instantly for corrugated cartons, cases, and other logistics applications.

What is an ITF-14 Barcode?

ITF-14 is a 14-digit barcode based on the Interleaved 2 of 5 symbology, specifically designed for packaging levels in the supply chain. It encodes a Global Trade Item Number (GTIN-14) which identifies trade items at various packaging levels. ITF-14 is characterized by its distinctive bearer bars (thick black borders surrounding the barcode), which help ensure reliable scanning on corrugated cardboard and other rough surfaces.

ITF-14 Structure and Format

An ITF-14 barcode consists of 14 digits structured as follows:

• Indicator Digit (1 digit): The first digit indicates the packaging level (0-9), with different numbers representing specific packaging hierarchies (e.g., 1 for inner pack, 2 for case, etc.).
• GS1 Company Prefix (Variable length): Assigned by GS1 to identify the manufacturer or brand owner.
• Item Reference (Variable length): Identifies the specific product type (combined with the GS1 prefix, this forms either a GTIN-8, GTIN-12, or GTIN-13).
• Check Digit (1 digit): A calculated digit using the Modulo 10 algorithm to verify the barcode's integrity.

The bearer bars surrounding the barcode are a critical component of the ITF-14 specification. They help prevent partial scans and improve readability, especially on corrugated surfaces where print quality may be less than ideal.

Indicator Digit Meanings

The indicator digit in ITF-14 provides valuable information about the packaging level:

• 0: Used when there is no specific packaging level declared, often for base unit items.
• 1: Typically represents inner packs or the primary grouping level.
• 2: Generally indicates a case or carton (secondary packaging).
• 3: Often used for a master carton or tertiary packaging level.
• 4: Typically represents a pallet or other higher logistical unit.
• 5: Often used for multi-packs or consumer units bundled together.
• 6-8: Reserved for additional packaging levels as needed.
• 9: Indicates a variable quantity item.

It's important to note that while these are common uses, the actual meaning of indicator digits can vary by industry or company-specific implementations.

When to Use ITF-14 vs. Other Barcode Formats

ITF-14 is specifically designed for packaging levels beyond the retail point-of-sale. Here's when to choose ITF-14:

• Corrugated Surfaces: The thick bars and bearer bar design make ITF-14 particularly suitable for printing on corrugated cardboard boxes and other rough surfaces.
• Fixed-Content Trade Items: When you need to identify cases, cartons, or other packaging units that contain a fixed quantity of the same item.
• Non-POS Scanning: For items that will be scanned in warehouses, distribution centers, and other supply chain environments, but not at retail point-of-sale.
• GS1 Compliance: When you need to comply with GS1 standards for trade item identification at the packaging level.

For applications requiring variable data (like expiration dates, batch numbers, or serial numbers), consider GS1-128 instead. For retail items scanned at point-of-sale, EAN-13, UPC-A, or EAN-8 are more appropriate.

ITF-14 Technical Specifications

ITF-14 barcodes follow specific technical standards to ensure reliable scanning:

• Symbology: Interleaved 2 of 5
• Characters: Numeric only (0-9)
• Length: Fixed at 14 digits
• Check Digit: Required (Modulo 10)
• Bearer Bars: Required (minimum width of twice the narrow bar)
• Quiet Zone: 10X minimum (X = narrow bar width)
• X-Dimension: 0.495 mm to 1.016 mm (target 0.635 mm)
• Bar Height: 31.75 mm minimum

Our generator handles all these technical details automatically to ensure your ITF-14 barcodes are fully compliant with GS1 specifications and will scan reliably in supply chain environments.
