Which barcode format should I choose for retail products?

For global retail products, EAN-13 is standard in Europe, Asia, and worldwide, while UPC-A is standard in the United States and Canada. For internal inventory, shipping, or custom text encoding, Code 128 is recommended.

What is the difference between Code 128 and Code 39?

Code 128 supports all 128 ASCII characters (numbers, uppercase/lowercase letters, and symbols) with higher data density. Code 39 is widely used in industrial and automotive applications but supports a smaller set of characters and produces wider barcodes.

Can I print generated barcodes directly onto product packaging and thermal labels?

Yes. Downloading the SVG vector format guarantees infinite scaling with razor-sharp edges on thermal label printers or high-resolution commercial printing presses.

Is my barcode data stored on your server?

No. All barcode calculations and vector renderings execute 100% locally within your web browser for complete confidentiality.
