Frequently Asked Questions

Common questions about barcode types and printing guidelines.

Which format should I use for retail products?

Use EAN-13 for international retail or UPC-A for North America. For carton outer packaging, use ITF-14.

Can I print these on regular desktop printers?

Yes. PNG and PDF exports print clearly on standard laser and inkjet printers, as well as dedicated thermal label printers.

How many barcodes can I generate in bulk?

You can generate up to 100 barcodes per batch in printable PDF sheet or ZIP archive formats.

What is the quiet zone requirement?

Keep a clean white margin on the left and right sides of your barcode so laser scanners can distinguish the start and stop characters.
