I once helped a kitchenware brand prepare for a nationwide retail launch. They had 350 SKUs and needed barcode labels for every product variation — different sizes, colors, and pack counts. The owner was about to manually generate each barcode one at a time. I showed him how to batch the entire thing in under 30 seconds.
Your product catalog is probably in a spreadsheet. Export it as CSV with one column containing the barcode data — UPC codes, GTINs, SKU numbers, whatever you need to encode. Or just use a plain text file with one value per line. That is it. No special formatting, no headers needed. Drop the CSV into our bulk barcode generator and it processes every row.
The bulk generator defaults to Code 128 — the safest general-purpose format for internal use. For retail barcodes that scanners need to read at point of sale, switch to EAN-13 or UPC-A.
For standard Avery 5160 label sheets (30 labels per page, 1"x2.63"), set the barcode height to 80px and width to 2. This fits one barcode per label with room underneath for the human-readable number. I tested this exact setup for a 350-SKU kitchenware brand — 30 seconds to generate, 5 minutes to print all 12 sheets. For larger runs, Code 128 at 80px fits Zebra ZT410 industrial printers at 203 DPI, which we ran 24 hours a day at Amazon. Our bulk generator outputs a printable page with all barcodes arranged on the sheet.
The best part: all processing happens in your browser. Your product data never leaves your computer. No uploading sensitive catalog information to some random server. Try the bulk barcode generator now →
