Introduction

In the world of barcode technology, there are several symbologies that have been developed to encode data in a unique and efficient manner. One such symbology is the Code 39 barcode, also known as the "3 of 9 code." This barcode is widely used in non-retail applications and is known for its ease of use and versatility. In this article, we will delve into the details of the Code 39 barcode, its encoding utility, and its various applications.

What is Code 39?

Code 39 is a discrete, self-checking variable-length barcode that can be easily printed by a variety of methods. It is a two-width code, meaning that every character has five bars and four spaces, making a total of nine elements. Of these nine elements, three are wide and six are narrow. The Code 39 symbol begins and ends with an asterisk (*) character, which serves as the start and stop code for the barcode.

Character Set and Encoding

The Code 39 character set consists of 43 characters, which may seem limited compared to other barcode symbologies. However, with the use of the Code 39 Full ASCII feature, it is possible to encode all 128 ASCII characters. This feature uses special symbols to encode characters such as lowercase letters. When a barcode reader is set to FULL ASCII mode, it can decode these special symbols and display the encoded data.

Modulo 43 Check Character

For specific applications that require data security, an optional modulo 43 check character can be used. This check character is used to verify the integrity of the encoded data and ensure that it has not been tampered with. The Health Industry Business Communications Council (HIBCC) uses this check character for health care applications.
