UPCgen

Free generator for valid UPC, EAN, ISBN, GTIN, and other barcodes.

Webfreeglobal

UPCgen generates valid UPC, EAN, ISBN, GTIN, ITF-14, Code 128, FNSKU, and Data Matrix barcodes on one clean page, aimed at Amazon FBA sellers printing FNSKU labels, Shopify/Etsy sellers adding GTINs, warehouses labeling cases, self-publishers generating ISBNs, and pharma operators needing compliance codes. It's honest about when a real GS1-registered number is actually required rather than pretending to issue free ones that collide with registered products.
