ITF-14 is commonly associated with outer cases and trade-item packaging. This tool accepts a 13-digit body or a 14-digit value, calculates or verifies the check digit, and renders an Interleaved 2 of 5-based barcode for review.
Trade packaging has requirements beyond the shape of the bars, including identifier assignment, symbol placement, dimensions, print quality, and quiet zones. Use this page to prepare and check artwork, then confirm it against your buyer’s specifications before production.
How to use this tool
- Enter the first 13 digits or a full 14-digit number.
- Generate the barcode and verify the check-digit message.
- Compare the printed dimensions with your packaging specification.
Practical guidance
ITF-14 is commonly associated with logistics labels for traded-unit packaging. It encodes a 14-digit GTIN structure and should be used only when that identifier and packaging workflow are appropriate. This tool calculates a check digit from 13 digits or verifies the complete value, but it does not validate the commercial assignment of the number.
Checks before you use the output
ITF-14 is often used with specific bar-height, magnification, bearer-bar, and placement requirements. This general image generator should be treated as a preview rather than a packaging-compliance certificate. Confirm the applicable GS1 and trading-partner specification, then test the final artwork with a production-quality scanner before releasing cartons or labels.
Questions and answers
Can this guarantee GS1 compliance?
No. It checks the digit format and creates a barcode image, but compliance also depends on identifier assignment and packaging specifications.
Where is ITF-14 normally used?
It is commonly used for trade items such as cases and cartons rather than consumer-facing individual retail units.
Can this file be used as a final logistics label without review?
Do not assume so. ITF-14 packaging has format and print requirements beyond checksum arithmetic. Check the applicable specification and test the production label before use.
