International retail

Use EAN-13. Accepted by virtually all supermarkets worldwide. Requires GS1 registration.

US retail / Amazon FBA

Use UPC-A. Required by most US retailers and Amazon FBA listings. Must purchase from GS1.

URL / mobile

Amazon FNSKU

Amazon FNSKU barcodes are free — get them from Amazon Seller Central → Manage Inventory → Print Item Labels. They're Code 128 underneath; paste the FNSKU string (e.g. X001ABC123) here and select Code 128 to generate your own.

💡 Selling in retail stores? You almost certainly need a GS1-issued UPC-A (US) or EAN-13 (international). Retailers scan these at point of sale — a self-generated Code 128 won't work for retail checkout.

Frequently Asked Questions

What is a bulk barcode generator?
A bulk barcode generator is a tool that lets you create multiple barcode labels at once from a list of values. Instead of generating barcodes one by one, you paste or upload a CSV or Excel file with hundreds of product codes, and the tool outputs all labels as a print-ready PDF or a ZIP of PNG images.
Is Bulk Barcode Generator really free?
Yes. Bulk Barcode Generator is completely free, with no hidden fees, subscription tiers, or trial limits. There is no row limit, no watermark, and no account required — ever.
What barcode formats does it support?
It supports six common formats: Code 128 (general inventory and internal SKUs), EAN-13 (international retail), UPC-A (US retail and Amazon FBA), Code 39 (legacy scanners), QR Code (URLs and mobile scanning), and Data Matrix (small-label industrial use).
Can I use this tool with a Zebra thermal printer?
Yes. In addition to PDF and PNG export, Bulk Barcode Generator can output barcodes as ZPL (Zebra Programming Language) commands that send directly to Zebra label printers — no driver configuration needed.
Do I need to sign up or create an account?
No. There is no account or signup required. Open the page, paste your values or upload your file, and download your labels immediately.
Does my data get uploaded to a server?
No. All barcode generation happens entirely in your browser using client-side JavaScript. Your product codes, SKUs, or any other data you enter never leave your device.
What file formats can I import?
You can paste values directly (one per line), or upload a CSV file or an Excel spreadsheet (.xlsx / .xls). Any column in the file can be selected as the barcode value source — no reformatting required.
How do I print barcode labels at the correct size?
Download the PDF, then open it in any PDF viewer. Set the print scale to 100% (or "Actual size") and disable "Fit to page." Labels are sized to match standard Avery and thermal label sheets at 300 DPI.
