Frequently Asked Questions

Which barcode format should I use?

EAN-13 and UPC-A are the universal standards for retail products scanned at checkout. If you sell commercially through supermarkets or Amazon, use the authorized number assigned by GS1. Code 128 and Code 39 are ideal for internal stock management, warehouse shelving, and equipment tracking where custom formatting is preferred.

Why did my EAN or UPC barcode get rejected?

EAN-13 requires exactly 12 digits (our generator calculates and appends the 13th check digit automatically). UPC-A requires exactly 11 digits. If you enter extra letters, spaces, or an incorrect length, an error will be displayed.

Can I download and print barcodes in vector SVG format?

Yes. The SVG download provides an infinitely scalable vector graphic. It ensures zero blur or pixelation when printed on industrial barcode label printers (such as Zebra or Brother label makers).

Is there any watermark or fee?

No. FreeQR Barcode Generator is 100% free with no registration, no watermarks, and no usage limits.
