Menu Home > Barcode FAQ > Interleaved 2 of 5 | ITF-14 Barcode FAQ & Tutorial: Interleaved 2 of 5 Barcode Overview Interleaved 2 of 5 ( ITF) is a numeric only barcode used to encode pairs of numbers into a self-checking, high-density barcode format. In this symbology, every two digits are interleaved with each other to create a single symbol. If a number string containing an odd number of digits needs to be encoded, a leading zero must be added to produce an even number of digits in the Interleaved 2 of 5 barcode. In many cases, the Code 128 barcode offers an advantage over the ITF barcode because it encodes even and odd numbers of digits, as well as letters and symbols, with nearly equal density. The symbology of the character set consists of barcode symbols representing numeric characters 00 to 99, the space character and start/stop characters. The complete printed barcode consists of a leading quiet zone, a start pattern, interleaved symbols representing data, an optional MOD 10 check character, a stop pattern, a trailing quiet zone and an optional bearer bar pattern surrounding the entire symbol. The IDAutomation Interleaved 2 of 5 Barcode Font Package provides 4 different font formats (as shown in the graphic to the right) to meet various requirements. These formats are, in the order they appear: Standard Standard Human Readable Bearer Bar Bearer Bar Human Readable The bearer bar versions are provided to meet certain specifications such GS1 ITF-14. Some of these specifications state that only horizontal bearer bars along the top and bottom of the barcode symbol are necessary, the bearer bar versions provided in this package completely surround the barcode which meet or exceed any bearer bar requirement. USS Interleaved 2 of 5 ( Uniform Symbology Specification Interleaved 2 of 5) is the published specification for Interleaved 2 of 5. All IDAutomation products.
