Interleaved 2 of 5 Overview
Interleaved 2 of 5
is a high-density numeric barcode type, which was primarily designed to be used in the distribution and warehouse industry. It is also known as ANSI/AIM ITF 25, ANSI/AIM I-2/5, Uniform Symbology Specification ITF, USS ITF 2/5, ITF, I-2/5, 2 of 5 Interleaved and 2/5 Interleaved.
Interleaved 2 of 5 is the compressed version of Code 2 of 5. Like Code 2 of 5, Interleaved 2 of 5 is a variable-length barcode symbology, which means that the number of data encoded is not fixed. Nevertheless, note that Interleaved 2 of 5 can encode even number of data only or a zero will be added to the beginning, because each symbol encodes two interleaving data characters. Besides, it can be decoded bidirectionally.

Interleaved 2 of 5 Structure
There are 5 elements per symbol character, which can be encoded as either five bars or five spaces. And two elements are wide while three are narrow. In addition, each Interleaved 2 of 5 barcode symbol image comprises five areas: leading quiet zone, start pattern, one or more pairs of symbol characters, stop pattern and trailing quiet zone.
Interleaved 2 of 5 Encodable Data
Interleaved 2 of 5 is a continuous numeric barcode type. That is to say the encodable data characters are numeric characters 0 through 9. And it encodes pairs of digits. This barcode encodes pairs of digits, with the first digit encoded in five bars, and the second in the interleaved five spaces.
Interleaved 2 of 5 Bearer Bar
Bearer bars will be used when the fixed symbol length can't be used in specified applications. It is used to reduce the probability of a valid but erroneous short read of the symbol where a scanning beam enters or leaves the symbol at the top or bottom. The width of the bearer bar should be between two and five times the narrow element width of the Interleaved 2 of 5 symbol.
Interleaved 2 of 5 Checksum Calculation
Interleaved 2 of 5 is self-checking, so its check digit is optional to enhance data security. You can easily implement a check digit by setting true to "ChecksumEnabled" with KeepAutomation Interleaved 2 of 5 barcode generators. One zero should be added as data character at the left of barcode symbol when the check digit is included. Below is the barcode image of an interleaved 2 of 5 with one check digit.
Here's how you can compute an Interleaved 2 of 5 checksum digit by yourself.
Sum all digit values in the even position, and multiply the result by 3;
Sum all remaining digit values;
Add the result of step1 to step2;
The total sum in step3 modulo 10 is the value of check digit.
