CODE128 for general alphanumeric data, EAN-13/UPC for retail products, ITF-14 for shipping cartons, CODE39 for legacy asset tags.
Why is my value rejected?+
Fixed-length types like EAN-13 need an exact digit count. The field hint shows the required format for the selected type.

Yes. Export as SVG for lossless scaling, or PNG at 3× for a sharp raster image.
Is my data uploaded?+
No. Barcodes are rendered in the browser with JsBarcode.
