What is UPCGen?

UPCGen is an online tool that takes a numeric identifier (such as a UPC or EAN) as input and produces a barcode image as output, complete with a valid check digit. It runs entirely in the browser, requiring no installation, and is developed by the UPCGen team. The service is designed to generate barcodes that meet GS1 standards and are accepted by major e-commerce platforms.

Click “Generate” to create the barcode image with a valid check digit. 4. Download the result in your chosen format (PNG, SVG, PDF, EPS) or export bulk data as CSV.

FAQ

Is UPCGen free?

Yes, there is a free tier that allows up to 1 barcode per 24 hours without signup, or 5 per 24 hours with a free registration. Paid subscriptions are available for unlimited or higher-volume generation.

Are the barcodes valid for Amazon and other platforms?

Yes. Each barcode includes a correct check digit and passes GS1 standard validation. Amazon, Walmart, Shopify, and other platforms accept these barcodes when the user provides a legitimate GTIN prefix.

Does UPCGen sell or assign real UPC numbers?

No. The tool generates barcode symbols from numbers you provide. It does not sell or assign GTIN prefixes. To obtain legitimate UPC/EAN numbers for commercial products, you must purchase a GS1 company prefix separately.

Can I generate FNSKU barcodes?

Yes, UPCGen includes a dedicated FNSKU generator that creates FNSKU labels compliant with Amazon FBA requirements.

What export formats are available?

You can download single barcodes as PNG, SVG, PDF, or EPS. For bulk generation, you can export a CSV file with barcode data or a multi-page PDF/PNG sheet of barcode images.
