The Interleaved 2 of 5 (ITF) Guide
High-density numeric encoding. Master the logic of Interleaved 2 of 5 barcodes for distribution, warehousing, and air freight tracking.
What is ITF?
Interleaved 2 of 5 (ITF) is a numeric-only barcode symbology used extensively in shipping, warehousing, and logistics. It is highly efficient because it encodes data in pairs: the first digit is encoded in the bars, and the second digit is encoded in the spaces.
Distribution ITF Generator
Generate high-resolution ITF barcodes for your distribution network. Use the Batch Distribution mode to import a list of shipment IDs or numeric identifiers from a spreadsheet.

The Even-Digit Requirement
Because characters are encoded in pairs (interleaved), an ITF barcode must always contain an even number of digits. If your data string has an odd number of digits, our generator will automatically add a leading zero.
