Bulk Barcodes for Amazon FBA & Retail

Amazon FBA sellers must label inventory with FNSKU barcodes, which use the Code 128 standard. Instead of generating them one at a time or paying for software, paste your full list of FNSKUs or SKUs here and create every barcode at once — then print them straight onto your label sheets. The tool also supports UPC-A and EAN-13 for retail products and Code 39 for asset tags.

Everything is produced in your browser with no account, no email and no per-code fee, so it scales from a handful of items to a whole shipment for free.
