What is an ITF barcode?

ITF (Interleaved 2 of 5) is a numeric barcode symbology that encodes digits in pairs using five bar elements per pair. It appears on cartons, distribution labels, and warehouse signage where numeric-only data must survive rough handling and corrugate printing. ITF shares the same encoding family as ITF-14; many logistics workflows use the terms interchangeably when specifying outer-pack barcodes.

Recommended generator settings

These defaults work well for preview and download. Adjust to match your label template or scanner tests.

Bar width Start at 2; increase only if scans fail at your print size
Height 100 px or taller for warehouse and logistics labels
Quiet zone Keep the default margin unless your spec defines a different quiet zone
Readable text Leave enabled when operators verify values manually
Output format PNG for design files; JPEG for documents and quick sharing

When should you use ITF?

  • Distribution labels that specify Interleaved 2 of 5 without ITF-14 naming
  • Warehouse rack and carton labels with numeric-only identifiers
  • Proofing ITF symbols before applying labels to corrugate shippers
  • Legacy WMS integrations that reference ITF rather than Code 128

Limitations and common mistakes

Consumer retail products need EAN or UPC symbologies. Alphanumeric warehouse data fits CODE128 better. Case-level GTIN labeling may explicitly require ITF-14 naming.

  • Including letters or symbols when this format accepts digits only.
  • Using the wrong digit count for this fixed-length symbology.
  • Trimming quiet zones when cropping the image for a label layout.
  • Scaling the barcode unevenly so bar width ratios no longer match the generated image.

ITF vs CODE128

Format Best for Supported data Key difference
ITF-14 Corrugated case labels in wholesale and retail distribution Exactly 14 digits Fixed-length numeric identifier with packaging level indicator.
Code 128 Set C Long numeric shipment or container references on warehouse labels Digits 0–9 only An even-length string of 0–9 encoded two digits at a time.
Code 128 Warehouse and inventory labels where the encoded value mixes letters and numbers Printable ASCII (codes 33–126) Alphanumeric flexibility with automatic check digit for mixed data.

Printing and scanning notes

Printing

  • Favor direct thermal or laser printing for crisp bar edges on corrugate.
  • Add bearer bars when your print vendor recommends them for ITF quality control.
  • Avoid excessive ink spread that merges adjacent bars on porous cardboard.

Scanning

  • Configure scanners for Interleaved 2 of 5 symbology.
  • Scan straight-on; angled reads on wide case labels reduce first-pass success.
  • Replace labels with physical damage to bars before warehouse put-away.

Frequently asked questions

Both use Interleaved 2 of 5 encoding. ITF-14 specifically denotes the 14-digit case identifier format common in logistics.

This generator validates the same 14-digit pattern used for case-level ITF symbols in the config.

No. Interleaved 2 of 5 is numeric only.

Bearer bars are often specified in print guidelines to improve scan reliability on corrugate.

Use ITF when your WMS or carrier mandates Interleaved 2 of 5; use Code 128 for alphanumeric IDs.

The value must be exactly 14 digits matching the validated pattern.

Yes. One valid 14-digit value per line.
