ITF-14 Barcode Generator
Create 14-digit ITF-14 barcodes for shipping cartons.
What is ITF-14?
ITF-14 (Interleaved 2 of 5, 14 digits) encodes a GTIN-14 and is printed on shipping cartons and cases rather than individual retail items.
How to create one
Enter 13 digits to auto-calculate the check digit, or a full 14-digit number to validate. Enable bearer bars — the heavy frame around the code — which is standard for carton printing.
How the check digit works
ITF-14 uses the same modulo-10 checksum as other GTINs. The results panel shows the payload, the computed check digit and the full 14-digit number.
Why bearer bars
Bearer bars help scanners read the code reliably on corrugated cardboard and reduce partial scans. They're part of the ITF-14 print specification for cases.
Scanning and printing tips
Because ITF-14 is printed large on packaging, follow the recommended dimensions, keep quiet zones, and print on a smooth enough surface for clean bars.
Limitations
ITF-14 encodes exactly 14 digits — it isn't for arbitrary text. A generated image doesn't create a registered GTIN.
Frequently asked questions
What are bearer bars?
The thick frame around an ITF-14 barcode. They improve scan reliability on cartons and are part of the print standard.
How many digits does ITF-14 use?
Fourteen. Enter 13 to auto-calculate the check digit, or a full 14-digit number to validate.
Is ITF-14 for retail items?
No. It is used on shipping cases and cartons, not on individual retail products.
