This draws the barcode graphic. A barcode that scans at a real retail checkout needs a product number assigned to you by GS1. Generating the image here does not register a number.

Questions people ask

What is Code 128 used for?

Logistics and supply chains: shipping labels, carton and pallet IDs, and internal asset or inventory codes. It handles the full ASCII set at high density, so it packs long alphanumeric values into a small label.

How many characters can Code 128 hold?

It is variable length and encodes all 128 ASCII characters. In practice keep it short enough to scan reliably on your label size; very long values make a wide barcode.

Is my barcode uploaded?

No. It is drawn in your browser with JavaScript and nothing is sent to a server.
