TS ISO/IEC 15417

TS ISO/IEC 15417 is the standard that specifies the Code 128 bar code symbology in automatic identification and data capture. The technical issue here is not just printing bars and spaces, but defining how a barcode alphabet represents data in a compact, machine-readable form with reliable scanning behavior. Code 128 is widely used in logistics, labeling, and traceability because it offers high data density and efficient use of label space.

The technical role of Code 128

Code 128 is a bar code symbology capable of encoding different types of data within the same alphabet. In general technical terms, symbologies like this allow product identifiers, serial numbers, batch information, and similar variable data to be captured quickly by automated systems. Its key advantage is the combination of compactness and information capacity, which makes it especially useful where label area is limited.

What this standard provides

• It addresses the characteristics of the Code 128 barcode alphabet and symbol structure.
• It provides a common technical reference for barcode consistency in automatic identification and data capture systems.
• It focuses on the encoding logic and readability of the symbol rather than on the physical appearance alone.
• It supports the common technical language used for printing, scanning, and interpreting barcodes across systems.

The focus of this standard is the symbology itself, meaning the bar pattern used to carry data. For users evaluating barcode technologies, the important distinction is that the same data content can behave differently across symbologies in terms of space usage and scanner performance. Within the barcode family, Code 128 stands out as a compact and versatile option.
