UPCgen - Free Barcode Generator for E-commerce

This free barcode generator helps people create standard barcode formats for retail, publishing, and fulfillment workflows without signing up. It supports UPC-A, EAN-13, ISBN, EAN-8, UPC-E, ITF-14, Code 128, FNSKU, and Data Matrix, and the site also points users to a QR code generator for links, WiFi, vCard, and similar use cases.

The product is aimed at sellers and operators working with platforms such as Amazon, Shopify, Etsy, eBay, Walmart, and Amazon KDP. The homepage emphasizes that generated codes have valid check digits and pass GS1 standard validation, and that they meet the requirements of major platform and supplier portals. It also offers step-by-step guides for adding barcodes to listings on those platforms.

Users can generate one barcode or large batches, with export options for CSV, PNG sheets, PDF, SVG, and EPS for professional print. The service supports anonymous generation with no account required, plus a registered option that increases the daily limit. For users with custom needs, the site says bespoke services are available for custom barcode workflows.
