Two-out-of-five, or 2 of 5, is an error detection and correction technique that uses two bits out of five and provides exactly ten combinations. Therefore it is perfectly suited for encoding the numerals 0-9 and can easily be incorporated into barcodes by using wide and narrow bars representing the on and off bits. LEADTOOLS 1D Barcode SDK supports all of the major 2 of 5 barcode symbologies employed throughout the world in various industries.

ITF / Interleaved Two of Five / Interleaved 2 of 5

Sample Barcode:

The ITF symbol is similar to standard 2 of 5 except that data can be stored in both the width of the bars and spaces; whereas, Standard 2 of 5 only stores data in the width of the bars. ITF is used widely in the shipping industry as it is especially suited to be printed directly onto packaging materials with poor printing quality such as corrugated cardboard. ITF can also be used to store EAN data structures.
