What is a Code 128 barcode?

Code 128 is a high-density linear barcode symbology. It's capable of encoding all 128 ASCII characters, making it very versatile. Code 128 barcodes are widely used in various industries including shipping and packaging, transportation, healthcare, and retail.

Like other barcodes, code 128 barcodes consist of bars and spaces of varying widths, with each character being represented by a pattern of these bars and spaces. Unlike some other barcode symbologies, Code 128 does not require a fixed number of characters per barcode; it dynamically adjusts the length of the barcode based on the data being encoded.
