Questions

Which barcode type should I use?

For your own labels, inventory or shipping, Code 128: it holds letters and digits and every scanner reads it. For products sold in shops, EAN-13 (or UPC-A in North America). For books, ISBN.

Do I need to register the number?

To sell a product in shops, yes: EAN and UPC numbers come from GS1, the organisation that runs the system. For your own stock, shelves or internal use, any number works.

How big should I print it?

Keep the bars crisp and give them space: print at 100% (don't stretch it), leave a white margin around the code, and use dark bars on a light background.

Is anything uploaded?

No. The code is made in your browser, and what you type stays on your device.
