What is Interleaved 2 of 5 used for?
Interleaved 2 of 5, usually written ITF, is a numeric-only symbology that packs two digits into every group of bars and spaces. That interleaving makes it unusually dense for numbers, which is why it persists in industrial and distribution settings where the payload is always numeric.
Because it has no self-checking structure, ITF must be printed at a fixed length that the scanner expects — otherwise a partial read can decode as a valid shorter number. Pick ITF only when a downstream system requires it; for general use Code 128 is safer.
- Industrial and distribution labels
- Carton and packaging codes
- Legacy numeric ID systems
