Interleaved 2 of 5 Barcode Generator
Quick answer: Interleaved 2 of 5, often abbreviated ITF, is a numeric linear barcode specified by ISO/IEC 16390:2007. Digits are encoded in pairs.
What Interleaved 2 of 5 is
Interleaved 2 of 5 is a high-density numeric linear symbology in which the patterns for digit pairs are interleaved between bars and spaces.
When to use Interleaved 2 of 5
Use Interleaved 2 of 5 when an industrial, warehouse or logistics system explicitly requires generic ITF. Use ITF-14 for GTIN-14 shipping cases.
Data and validation rules
The symbology encodes numeric data and works with paired digits, so the final encoded length must suit the implementation.
Standards and governance
Interleaved 2 of 5 is specified by ISO/IEC 16390:2007. Generic ITF does not assign the numeric value. Governed identifiers such as GTIN-14 still require their applicable rules.
Printing and scanner testing
Maintain correct wide-to-narrow relationships, quiet zones and sufficient bar width for the target printer.
Common mistakes to avoid
Common failures include odd-length data handling errors, confusing generic ITF with ITF-14 and allowing print gain to close narrow spaces.
How Interleaved 2 of 5 compares with related formats
Interleaved 2 of 5 is the general symbology. ITF-14 is a GS1 application using it to carry exactly a GTIN-14 with additional requirements.
Before you print
- Correct symbology selected
- Identifier ownership confirmed
- Check digit verified
- Quiet zones kept clear
- Strong bar contrast
- Aspect ratio unchanged
- SVG or high-resolution PNG
- Production scanner test
