What Is ITF-14?
ITF-14 (Interleaved 2 of 5 — 14 digits) is a fixed-length numeric barcode symbology designed to encode a 14-digit Global Trade Item Number (GTIN-14) on outer packaging, corrugated cartons, and wholesale shipping cases. Standardized under ISO/IEC 16390 and the GS1 specification, ITF-14 is built on the Interleaved 2 of 5 (ITF) symbology, which encodes digit pairs by interleaving bars and spaces — producing a compact, high-density pattern tolerant of the lower print quality typical of corrugated cardboard. The final 14th digit is a GS1 check digit (Mod 10), calculated automatically to guarantee scan integrity throughout the supply chain. ITF-14 is mandatory on trade items sold by the case or pallet to retailers, wholesalers, and distribution centers worldwide.
- Fixed 14-Digit GTIN — Built for Outer Carton LabelingITF-14 always encodes exactly 14 numeric digits representing a GS1 GTIN-14. The first digit is a packaging indicator (1–8) that identifies the level of packaging — cases, pallets, inner packs, or display units. The remaining 12 digits carry the company prefix and item reference, and the 14th digit is the GS1 Mod 10 check digit. This fixed structure is understood by every retail and logistics scanning system worldwide, ensuring your outer carton is correctly identified at every point in the supply chain.
- Interleaved 2 of 5 Encoding — Optimized for Corrugated SurfacesITF encodes digit pairs by interleaving the bars of one digit with the spaces of the next, producing a continuous high-density symbol with no inter-character gaps. This design results in a shorter, more robust barcode than non-interleaved numeric symbologies, making it well-suited for corrugated cardboard where ink spread and surface irregularities are common. The bearer bars — thick horizontal rules above and below the barcode — are a GS1-required feature that prevents partial scans and ensures reliable reads on curved or uneven packaging surfaces.
- Automatic GS1 Mod 10 Check DigitThe 14th digit of every ITF-14 barcode is a GS1 Mod 10 check digit, calculated automatically from the first 13 digits. You never need to compute or append it manually — the generator derives it from your input and validates the full 14-digit string before rendering. Scanners verify the check digit on every read and reject misreads, providing a critical error-detection layer across high-volume warehouse and retail scanning environments.
- GS1 Standard: Required for Wholesale and Retail DistributionITF-14 is the GS1-mandated barcode for shipping cases and grouped trade items sold to retailers and distributors. Major retailers including Walmart, Target, Costco, Tesco, and Carrefour require ITF-14 on all inbound case-level shipments. It is also required for EDI compliance, SSCC pallet labels, and receiving systems in third-party logistics (3PL) warehouses. If you supply products in multi-unit cases to any retail chain or distributor, ITF-14 is the barcode standard you must meet.
- High Print Tolerance — Readable on Corrugated CardboardITF-14 is specifically designed for direct printing on corrugated cardboard using flexography, thermal transfer, and inkjet printing — processes with wider tolerances than those used for retail shelf labels. The GS1 specification defines a minimum X-dimension of 0.635mm (much wider than EAN-13 or Code 128) and allows print quality grades down to 1.5 on a 0–4 scale. This makes ITF-14 reliably scannable even when printed on uneven, recycled, or rough-surfaced corrugated substrates.
ITF-14 Barcode Generator Features
Everything you need to create production-quality ITF-14 barcodes — from real-time preview and automatic check-digit calculation to bulk generation, bearer bar control, size adjustment, and lossless SVG output.
Automatic Mod 10 Check Digit Calculation
Enter your 13-digit GTIN prefix and the generator automatically computes and appends the correct GS1 Mod 10 check digit to produce a valid 14-digit ITF-14. No manual calculation required. If you enter all 14 digits, the check digit is validated against the standard and any mismatch is flagged before the barcode is rendered — preventing invalid barcodes from reaching your labels.
Real-Time Preview as You Type
The ITF-14 barcode preview updates live with every keystroke. See the exact barcode that will be generated — including bar pattern, bearer bars, human-readable text, and proportions — before downloading. Non-numeric characters and strings with incorrect digit counts are flagged immediately, so input errors are caught before they reach a printer or label production run.
PNG and SVG Download
Download your ITF-14 barcode as a high-resolution PNG for documents, purchase orders, and email attachments, or as a lossless SVG for print-ready label templates and vector graphics workflows. SVG barcodes scale to any physical size without pixelation, making them ideal for large carton labels, artwork files, and direct integration into design or label software.
Adjustable Width, Height, and Quiet Zone
Control the physical dimensions of your ITF-14 barcode: bar height, module width (X-dimension), and quiet zone margin. GS1 specifies a minimum bar height of 32mm and quiet zones of at least 10× the X-dimension on each side — all enforced automatically at default settings. Adjust dimensions to fit your specific carton label size while maintaining GS1 compliance requirements.
Human-Readable Text — Show or Hide
Toggle the human-readable interpretation (HRI) text below the ITF-14 barcode on or off. When enabled, the 14-digit GTIN is printed beneath the bars in standard GS1 formatting, allowing warehouse operators and retail staff to read the value visually without a scanner. Hide the HRI when embedding the barcode in custom label designs that display the GTIN in a separate text field.
Bulk Barcode Generation
Generate ITF-14 barcodes for an entire product catalog in a single session. Paste one GTIN per line into the input area and the generator produces a barcode for each entry simultaneously. Export all barcodes as individual files or as a ZIP archive. Ideal for brand owners and contract packers who need to label multiple SKUs, case configurations, or packaging tiers in one batch.

ITF-14 Barcode — Frequently Asked Questions
Technical answers to the most common questions about ITF-14 encoding rules, GTIN structure, check digits, print requirements, and GS1 compliance.
What is an ITF-14 barcode used for?
ITF-14 is used to identify trade items at the case, inner pack, display unit, or pallet level in wholesale and retail supply chains. It encodes a 14-digit GS1 GTIN-14 on the outer packaging of grouped products — for example, a case of 12 consumer units. Retailers and distributors scan ITF-14 barcodes during receiving, put-away, and inventory replenishment. It is not used on individual consumer products at point of sale; that role is filled by EAN-13 or UPC-A.
What is the difference between ITF-14 and ITF?
ITF (Interleaved 2 of 5) is the general-purpose numeric symbology that can encode any even number of digits at any length. ITF-14 is a specific application of ITF mandated by GS1 that always encodes exactly 14 digits representing a GTIN-14, includes mandatory bearer bars above and below the symbol, and must meet GS1 dimensional and print quality specifications. If you need to comply with retail or wholesale supply chain requirements, you need ITF-14 specifically — not plain ITF.
How do I calculate the ITF-14 check digit?
The ITF-14 check digit (digit 14) is calculated using the GS1 Mod 10 algorithm applied to the first 13 digits. Multiply alternating digits by 3 and 1 starting from the leftmost digit (position 1 × 3, position 2 × 1, etc.), sum all products, then subtract the result from the next multiple of 10. This generator computes the check digit automatically — enter your 13-digit GTIN prefix and the correct check digit is appended before the barcode is rendered.
What is the packaging indicator digit in ITF-14?
The first digit of a GTIN-14 is the packaging indicator (also called the logistic variant digit). It distinguishes different packaging levels of the same underlying product. A value of 0 is typically used when the GTIN-14 is derived from a GTIN-13 by zero-padding. Values 1–8 indicate different packaging configurations — inner pack, display shipper, case, pallet layer, etc. The packaging indicator is assigned by the brand owner and must be unique across all packaging tiers for the same item.
What are bearer bars and are they required?
Bearer bars are thick horizontal lines printed above and below the bars of an ITF-14 barcode. They are required by GS1 for all ITF-14 symbols. Bearer bars serve two purposes: they act as a frame that prevents scanners from attempting to decode partial scans where only part of the barcode is within the scan line, and they provide structural support for the bars during printing on corrugated surfaces where press pressure can distort narrow elements. GS1 specifies that bearer bar thickness must be at least 3× the X-dimension (minimum module width).
What are the minimum size requirements for ITF-14?
GS1 specifies a nominal ITF-14 symbol width of 142.75mm × 32mm at 100% magnification (X-dimension = 1.016mm). The allowable magnification range is 25%–200%, giving a width range of approximately 35.7mm to 285.5mm. For corrugated cardboard printing, GS1 recommends a minimum magnification of 62.5% (X-dimension ≥ 0.635mm). The quiet zone on each side must be at least 10× the X-dimension, with a minimum of 3.175mm. This generator enforces these minimums by default at standard label sizes.
Can I use ITF-14 for products sold individually at retail?
No. ITF-14 is designed for case-level and grouped-item identification in logistics and wholesale channels, not for individual consumer units scanned at point of sale. Retail POS systems are typically programmed to scan EAN-13 (13 digits) or UPC-A (12 digits) on individual products. If you encode a GTIN-14 on a consumer-facing product as an ITF-14, most retail checkout scanners will either misread or ignore it. Use EAN-13 or UPC-A for products sold individually.
Is my data safe when using this generator?
Yes. All ITF-14 encoding is performed entirely in your browser using client-side JavaScript. Your GTIN data — including company prefixes, item references, and packaging identifiers — is never transmitted to any server and never stored. Close the browser tab and all data is cleared. This tool is safe to use with proprietary product codes and pre-launch SKU data.
