ITF-14 barcode generator
ITF-14 marks shipping cartons and cases with a GTIN-14. Type the first 13 digits and the check digit is added. The code is framed by bearer bars, which keep a misread from happening when the bars print unevenly on corrugated board.

Fits a 4 × 2 in label (Letter, 10 per sheet).

Check digit 3 added (GS1 modulo-10).
How to use it
- Type the 13 digits: the packaging indicator (1–8) followed by the first 12 digits of the GTIN-13 of the item inside. The check digit is recalculated for the GTIN-14.
- Keep the module between 0.495 and 1.016 mm, the GS1 range for ITF-14. Larger modules scan better when printed directly on corrugated board.
- Keep the bar height near 32 mm (1.25 in) for scanning in distribution centres.
Building a GTIN-14
Take the GTIN-13 of the retail item (or a UPC-A with a leading 0), drop its check digit, put the packaging indicator in front, and calculate a new check digit. For example, item 5901234123457 in a case of 12 with indicator 1 becomes 1 590123412345 and check digit 4: 15901234123454.
Size and print
GS1 allows module widths from 0.495 mm to 1.016 mm for ITF-14, with a wide-to-narrow bar ratio of 2.25–3.0 and a quiet zone of at least 10 modules inside the bearer frame.
Questions
- Can I use ITF-14 on a retail product?
- No. Point-of-sale scanners expect UPC or EAN. ITF-14 is for cases and cartons that are not sold at a till.
- What is the packaging indicator?
- The first digit of a GTIN-14 (1–8) that tells different pack levels of the same item apart, for example 1 for a case of 12 and 2 for a case of 24.
