Which barcode formats does this online generator support?

It supports common barcode formats including Code 128, Code 39, EAN-13, EAN-8, UPC, ITF-14, GS1-128, PDF417, QR Code, DataMatrix and ISBN.

Is batch barcode data uploaded?

Barcode content, batch lists and local templates are primarily handled in the browser, which works well for order IDs, asset tags, shelf labels and everyday labeling data.

How do I create barcode labels from Excel or CSV online?

Prepare one barcode value per row, import or paste the Excel or CSV data into the batch generator, choose Code 128 for most internal IDs, preview the first labels, then export PNG, SVG, ZIP, Excel or print-ready files.

How do I generate sequential Code 128 barcodes online?

Use the AI Assistant or the batch generator to define a prefix, start number, quantity and padding. For example, ASSET-0001 with 30 labels creates ASSET-0001 through ASSET-0030 as Code 128 barcodes.

What barcode type should I use for warehouse asset labels?

Code 128 is the safest default for warehouse asset labels because it supports mixed letters and numbers, works well for internal IDs and stays compact. QR Code is better for URLs or long text, while DataMatrix can fit very small industrial labels.

Why is my printed barcode not scanning?

Most scan failures come from invalid barcode content, the wrong format, small size, missing quiet zones, low contrast, distorted scaling or low print quality. Test the original preview first, then adjust size, margins, color contrast and export resolution before printing again.

Should I use EAN-13 or UPC-A for retail packaging?

Use UPC-A for many North American retail workflows and EAN-13 for many international retail workflows. Packaging and marketplace listings typically require a valid UPC, EAN or GTIN source. For internal labels, Code 128 is often more flexible.
