What Are Code 128 Barcodes Used For?


Did you know there are about 100 different types of barcodes in existence today? One essential type of barcode often used in comprehensive asset and inventory management processes is Code 128 which is a high-density 2D barcode symbology widely used across various industries due to its versatility and ability to encode all 128 alphanumeric characters and special characters. 

It's one of the most popular types of barcodes, with three code sets and several GS1-128 barcode types. It's one of the more dependable barcodes with a wide range of uses because of the character values it can contain. It's a variable-length barcode, as in it doesn't have a fixed length. That means it can efficiently encode digits, text, control characters, and the full ASCII 128 character set, making it suitable for a range of applications.

Most online barcode generators can develop a Code 128 barcode in a few simple steps, as well as the barcode software applications available from Wasp. 

What Makes the Code 128 Barcode Unique?

Code 128 is a high-density linear barcode that can represent all 128 ASCII characters, including uppercase and lowercase letters, numbers, symbols, and control codes, which allows for extensive encoding capabilities in a compact format. This capability makes it ideal for applications in shipping, packaging, inventory management, logistics, ID cards, and some medical applications with GS1-128 barcodes. 

Code 128 barcodes are known for their versatility and efficiency in encoding various types of data.

The Code 128 barcode’s high density enables it to store a significant amount of information within a small physical space. This characteristic is particularly beneficial in environments where space is limited.  

What Are the Components of a Code 128 Barcode?

A Code 128 consists of several key components: quiet zones (margins on either side for readability), a start character (indicating the encoding mode), data characters (which represent the actual encoded information), a check digit or check character (for error detection), and a stop character (signaling the end of the data). The design of the "bar code" consists of bars and spaces of varying widths that correspond to different characters, allowing for dense data storage. All these features pass through the barcode scanner as it deciphers the alpha-numeric values. 

It exhibits high reliability in scanning, ensuring accuracy in data capture, even in challenging conditions such as low light or poor alignment. That's because of the check digit encoded in the barcode symbol, which uses a check character calculation.

Code 128 is also known by multiple names, including ANSI/AIM Code 128 and USS Code 128, highlighting its standardized use in various industries. Code 128 barcodes are an essential tool for modern inventory and tracking systems.

How Do Various Industries Use Code 128 Barcodes?

Due to its robust design and high reliability, the Code 128 barcode is widely adopted across various industries, providing a reliable solution for tracking and managing products efficiently.

  • Food and Beverage: Used to track inventory and ensure quality control along the supply chain. Example: Supermarkets use Code 128 barcodes to manage expiration dates and trace the source of produce, enhancing food safety.

Shipping and Packing: Used to streamline logistics via package labeling, allowing for efficient scanning and tracking as items move through warehouses and transportation networks, ensuring timely deliveries.

Healthcare: Hospitals and facilities utilize Code 128 barcodes to track medication and equipment. By scanning these barcodes, healthcare professionals can verify patient information and track pharmaceuticals, minimizing medication errors and improving patient safety. 

Government: Used for various purposes, including document management and public services, ensuring accurate tracking and inventory control. Example: Local government offices may use barcodes to track application packets for permits, streamlining processes and enhancing accountability. 

Is the Code 128 Barcode the Same as the Other Barcodes with "128" in Their Names?

Other barcodes with "128" in their names, such as Code 128A, Code 128B, and Code 128C, are variants of the Code 128 standard. They differ primarily in the character sets they support:

  • Code 128A includes uppercase letters. 
  • Code 128B accommodates both uppercase and lowercase letters.
  • Code 128C is optimized for encoding numeric data.

GS1-128 barcodes, on the other hand, is a specific application of Code 128, incorporating additional industry standards for use in supply chain management. It includes the use of application identifiers, item numbers, and company codes that provide context to the data encoded, enhancing its functionality for identifying products and conveying relevant information. 

GS1-128 may also be referred to as UCC/EAN-128, EAN-128, and GS1/UCC 128 in various software and literature. While Code 128 is versatile for general use, GS1-128 is tailored for compliance with international data standards in commercial contexts, emphasizing its specialized purpose.
