Industrial 2 of 5 - Dynamsoft Barcode Reader SDK

What is a Industrial 2 of 5?

Developed first in 1968, Industrial 2 of 5 is a low-density barcode that forms a part of the Code 2 of 5 symbology family. "2 of 5" signifies the number of digits encoded with the five bars, two of which are always wide and the remaining three being narrow.

The structure of the Industrial 2 of 5 barcode is very easy to understand as all the information is encoded in the width of the bars. On the hand, the spaces perform the function of separating the bars themselves.

Below is what a typical Industrial 2 of 5 barcode looks like:

Comparison of Two-Out-of-Five Barcode Variants

All three symbologies belong to the two-out-of-five barcode family, meaning each digit is represented using five total encoding units (either bars, spaces, or a combination of both).

• Industrial 2 of 5 encodes each digit using five bars.
• Interleaved 2 of 5 encodes digits in pairs, with the first digit represented by five bars and the second by five spaces.
• Matrix 2 of 5 encodes each digit using five elements, which may include both bars and spaces in a continuous (non-interleaved) pattern.

Feature	Industrial 2 of 5	Interleaved 2 of 5 (ITF)	Matrix 2 of 5
Encoding Width	Two-width (wide and narrow)	Two-width (wide and narrow)	Two-width (wide and narrow)
Encoding Method	Encodes data only with black bars	Digits are encoded in pairs; the first digit is encoded in the five bars (black lines), while the second digit is encoded in the five spaces (white lines) interleaved with them.	Encodes data using both black bars and white spaces in a continuous mode (not interleaved).
Wide Bar/Space Rule	Two out of every five bars are wide	Two out of every five bars or spaces are wide	Two out of every five bars or spaces are wide
Length	Variable length	Variable length (only even numbers of digits can be encoded; odd numbers typically require a leading zero)	Variable length
Density	Low density	High density	Moderate density
Character Set	Digits (0-9)	Digits (0-9)	Digits (0-9)
Check Character	Not typically used	Optional checking character	Optional checking character
Variants	Used in USPS (POSTNET, PLANET), and Code 39	ITF-14 (widely used for shipping and logistics)	Datalogic 2 of 5
