Frequently asked questions

Find answers to common questions about Code 128.

What is Code 128?⌄

Code 128 is a high-density linear barcode that can encode alphanumeric data.

What is the difference between Code Set A, B and C?⌄

Code Set A supports a more limited printable range in this V1 interface, Code Set B supports common printable ASCII characters, and Code Set C encodes digits in pairs.

Which Code Set should I use?⌄

Automatic is recommended for most users. Choose a specific set only when your workflow requires it.

Does Code 128 include a check digit?⌄

Yes. The Code 128 checksum is generated automatically as part of the barcode symbol; you do not enter it yourself.

Is Code 128 the same as GS1-128?⌄

No. GS1-128 uses Code 128 symbology with GS1-specific data structure and conventions. It is a separate workflow.

Can I download Code 128 as SVG or PNG?⌄

Yes. Download the current valid Code 128 barcode as SVG or PNG.
