Structure of ITF-14
ITF-14 is a continuous barcode. Each symbol character of ITF-14 comprises five bars (dark bars) and 5 spaces (light bars). Those five bars are made of two wide bars and three narrow bars.
ITF-14 is constructed of 7 parts: starting & stopping quiet zone, start & stop pattern, logistic variant, product number and a check digit.
ITF-14 barcode symbol has a unique Bearer Bar that is usually mandatory. But for some specified applications, it can be removed. And there are two reasons for implementing this bearer bar. One is to equalize the pressure exerted by the printing plate over the entire surface of the symbol. And the other is to enhance reading reliability. When a skewed scanning beam enters the barcode symbol through its top or bottom edge, this bar can help reduce the probability of misreads or short scans.
Quiet Zone is a white space surrounding the ITF-14 barcode image, which is able to protect the ITF-14 symbol. You may set quiet zone of left, right, top, and bottom according to your needs with KeepAutomation ITF-14 barcode generators.
Start and Stop Pattern
Start and Stop Pattern is an indicator to show the beginning and ending of the data sequence respectively, which is necessary for producing a valid ITF-14 barcode.
Encodable Data of ITF-14
ITF-14 is a numeric barcode, which is able to encode 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Each ITF-14 contains 14 digits which can be divided into five parts: digit 1 (packaging indicator), digits 2-3 (number system), digits 4-8 (manufacturer number), digits 9-13 (item number) and digit 14 (check digit).
Packaging Indicator, also called Logistic Variant, is the first digit of the ITF-14 barcode. It is used to distinct package type.

Product Number consists of three parts: an UPC numbering system or EAN prefix represented by the 2nd to 3rd digit, a Manufacturer identification number represented by the 4th to 8th digit, and an Item identification number represented by the 9th to 13th digit.
ITF-14 barcode has a mandatory check digit, which may be calculated on Modulo 10 algorithm that uses single-digit Arabic numerals 0-9 to represent. The checksum calculation is similar to UPC-E Checksum Calculation.
