Which code do you need?
- EAN-13: The global standard for retail products. 12 digits in, check digit out, scannable by every checkout in the world.
- Code 128: The most flexible general-purpose code — letters, digits, and symbols in a compact format for labels and logistics.
- Numbers vs text: EAN-13 is numbers only; Code 128 handles any printable ASCII text.
