Code 128: The Modern Standard for Logistics
A high-density barcode symbology designed for logistics, healthcare, manufacturing, and supply chain operations worldwide.
What Is Code 128?
Code 128 is one of the most versatile and efficient linear barcode standards available today. Developed for high-density data encoding, it is capable of storing significantly more information in less space than many older barcode symbologies.
Due to its compact design and extensive character support, Code 128 has become the preferred barcode format for shipping labels, warehouse management systems, medical applications, and industrial asset tracking.
What Makes Code 128 Unique?
Unlike simpler barcode formats that are limited to numbers or a small set of characters, Code 128 supports the entire ASCII character set.
- Uppercase letters (A-Z)
- Lowercase letters (a-z)
- Numbers (0-9)
- Special symbols
- Control characters
- Extended ASCII support
High-Density Data Encoding
One of the major advantages of Code 128 is its ability to store large amounts of information while occupying relatively little horizontal space.
Compared to older barcode formats such as Code 39, Code 128 can represent the same data using fewer bars, making it ideal for labels with limited printing space.
Key Applications
