    A valid check digit does not prove the underlying product code, ISBN, or SKU is correct—confirm source data separately.

  • Ignoring quiet zone requirements

    Scanners need margin around bars. Use the quiet-zone helper when layout specs are part of your print checklist.

    EAN-13, UPC-A, ITF-14, and Code 128 serve different lanes—match the validator to the label standard you were given.
