FAQ
Why is Code 128 popular?+
It supports full ASCII and is ~30% denser than Code 39 โ the de facto standard for logistics and tracking.
Maximum characters?+
No hard limit, but 20โ25 characters is the practical sweet spot. Longer bars become hard to scan.
Korean support?+
Code 128 supports ASCII only. Use QR codes for Korean text.
How does Code 128 A/B/C switching work?+
This tool uses jsBarcode's auto mode. Numeric runs switch to Code C (2-digit pack); text uses A/B.
Is GS1-128 different?+
GS1-128 (formerly EAN-128) adds Application Identifiers on top of Code 128. This tool produces plain Code 128.
Checksum?+
Code 128 requires a modulo-103 checksum that jsBarcode appends automatically.
