What is Code-128?

Code-128 is a high-density linear barcode symbology that encodes the full ASCII character set (numbers, letters, symbols, and control codes). It was developed to provide a more compact and reliable encoding method than older formats like Code 39. Code-128 is widely used in industries such as logistics, warehousing, retail, and healthcare.

There are three subsets of Code-128:

• Code 128A: Includes uppercase letters, numbers, and control characters.
• Code 128B: Includes upper and lowercase letters plus numbers.
• Code 128C: Optimized for numeric-only data, allowing pairs of digits to be encoded efficiently.

Because of its compact size and flexibility, Code-128 is perfect for small labels, shipping stickers, or any product where space is limited but accuracy is vital.
