About this tool
Stock tracking, shelf labels, shipping boxes or retail products — barcodes are useful for every small business. This tool generates them in your browser; your code list is never uploaded.
Code 128 accepts letters and numbers, ideal for your own SKUs. EAN-13 is the retail standard; type 12 digits and the check digit is calculated for you.
In the A4 label tab pick a ready-made label layout (24, 40 or 65 per sheet), paste hundreds of codes and download a print-ready PDF.
Frequently asked
No. Barcodes are generated in your browser; your code list is never sent to a server and never stored.
If you type 12 digits we compute the 13th with the standard mod-10 formula. If you type 13, we verify the last digit and correct it when wrong.
The barcodes are visually valid and scannable. However, an EAN number used in retail must be registered to you — get yours from your national GS1 organisation.
The presets follow common A4 label sheet sizes. Before the first run, print one page on plain paper and hold it against your label sheet. Make sure printer scaling is set to 100% (no 'fit to page').
Code 128 for your own stock codes (it accepts letters). EAN-13 for products that will be scanned at a retail checkout.
