Common mistakes to avoid

• Checking format without verifying human-readable data

  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.

• Using the wrong symbology for the supply chain

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