What is a Code 128 barcode?

Code 128 is a high-density linear barcode symbology that is commonly used in logistics, shipping, and inventory management for encoding complex data. Unlike other barcode types such as UPC or EAN, Code 128 can encode letters, numbers, and special characters, making it versatile for various industries. It is not tied to a specific system like GS1 but is widely used across many applications where detailed data needs to be stored compactly.

How much data can a Code 128 barcode hold?

A Code 128 barcode can hold up to 128 characters, which can include a combination of numeric, alphanumeric, and special characters. This makes it far more flexible than barcodes like EAN-8 or UPC, which are limited to numeric digits. Code 128 is structured into three subsets—A, B, and C—each of which handles different character sets, providing broad flexibility.
