Which type should I use?

Code 128 for general labels and logistics, EAN-13 or UPC-A for retail products, ITF-14 for shipping cartons, Code 39 where a legacy system requires it.

Can I invent an EAN or UPC number for my product?

No. Retail numbers must be licensed from GS1 so they are globally unique. This tool draws the barcode for a number you already own.

Is GS1-128 supported?

Not as a dedicated type. Plain Code 128 is supported; GS1-128 application identifiers with FNC1 are planned.

Is what I type sent to a server?

No. The code is generated in your browser. Passwords, payment IDs and contact details never leave your device.
