FAQ

Is the barcode generator free?

Yes. No signup. Type a value, click Generate, and the barcode is already on a real-size label in the free maker. Download PNG or PDF, or print.

Can I print these barcodes on a Zebra?

Yes. Generate opens the label maker. Print uses free Zebra Browser Print, or download PNG, PDF, or ZPL for other printers.

Do you sell UPC or EAN numbers?

No. The UPC and EAN tools draw bars for digits you already own. Buy retail numbers from GS1. Internal SKUs can use CODE128.

Can I open a label that is already filled in?

Yes. Generate from a tool, or open a link that already has the value in it. The barcode or QR is on the label when the maker opens. No signup.

Open a barcode for SKU-1001. Open a contact QR.
