Generate Code 128C BarcodeWhat is a Code 128C Barcode?
Code 128C is subset C of the Code 128 symbology. It encodes numeric data as pairs of digits (00–99), effectively doubling the data density compared with other subsets. This makes it ideal for long numeric strings such as SSCC and GS1 numbers, serial numbers, and check digits. Like every Code 128 symbol, it includes the mandatory mod-103 check character for reliable error-checked scanning.
In short: Code 128C is the subset C of Code 128 that encodes numeric data as pairs of digits (00–99), doubling the density for long numeric strings, with a mandatory mod-103 check character.

Code 128C Barcode – Frequently Asked Questions
Quick answers about how Code 128C works and where to use it.
Code 128C is subset C of Code 128. It encodes numeric data as pairs of digits (00–99), doubling the density, and is ideal for long numeric strings such as SSCC and GS1 numbers.
Code 128C is numeric-only and encodes pairs of digits from 00 to 99. It cannot encode letters or punctuation.
128A encodes uppercase letters and ASCII control characters (00–95), 128B encodes all printable ASCII (32–127) including lowercase, and 128C encodes numeric data as pairs of digits for double density.
Yes. Every Code 128C symbol includes the mandatory modulo-103 check character that scanners use to validate the data.
Use 128C whenever your data is purely numeric, especially for long strings like SSCC, GS1 numbers, serial numbers, and check digits—it produces the smallest possible symbol.
Yes. GS1-128 uses Code 128C for dense numeric payloads, making it the best subset for SSCC, GSIN, and other GS1-128 numbers with check digits.
