Barcode FAQ

What is the free barcode generator?

The free barcode generator creates scannable SVG barcodes for ecommerce products, SKU labels, inventory tags, and simple retail packaging. It supports EAN-13, UPC-A, and Code 39 formats directly in your browser.

Can I create a UPC or EAN barcode without a check digit?

Yes. Enter the first 11 digits for UPC-A or the first 12 digits for EAN-13 and the tool calculates the final check digit automatically. If you paste a full code, it validates the check digit and explains the correction if needed.

Which barcode format should ecommerce sellers use?

Use UPC-A for most US retail products, EAN-13 for international product labels, and Code 39 for internal SKUs, warehouse bins, samples, and non-retail inventory labels.

Are these barcodes official GS1 retail barcodes?

No. The generator creates the visual barcode from the numbers you enter. For official retail use, buy or assign valid GS1 company-prefix numbers, then use this tool to render a clean label.

Can I download the barcode?

Yes. You can download the barcode as an SVG file, export a PNG image, copy the SVG markup, or print the label from the browser.
