Frequently Asked Questions (FAQ)

Why is my barcode showing an error?

Certain barcode formats have strict mathematical rules. For example, a UPC-A barcode must be exactly 11 or 12 numeric digits long. It will reject letters. If you see an error, switch to Code 128, which is universal and accepts any combination of letters, numbers, and symbols.

Is my product data private?

Yes. This tool uses client-side JavaScript to draw the barcode directly inside your web browser. Your SKU numbers or text data are never sent to a server, ensuring 100% privacy and security.
