Introduction
UPC Gen is a free barcode generator online that creates valid UPC, EAN, and other barcodes. This tool helps sellers quickly produce platform-approved codes for Amazon, Shopify, and Walmart without requiring a signup.
What is UPC Gen?
UPC Gen is a web-based barcode generator designed for e-commerce sellers, product manufacturers, and small business owners who need to create valid, GS1-standard barcodes.

It is suitable for anyone selling on Amazon FBA, Shopify, Walmart, or KDP. Each generated code passes GS1 validation, ensuring it works across major retail platforms. The service is trusted by users on over 50 platforms and offers step-by-step guides for adding barcodes to listings.
