Frequently Asked Questions

How do I create a barcode for free?

Simply choose your desired format like CODE128 or EAN13, type your product code into the tool, and click download. Our barcode generator is completely free to use and requires no account sign-up.

What is the difference between UPC and EAN barcodes?

UPC (Universal Product Code) is a 12-digit barcode primarily used in the United States and Canada. EAN (European Article Number) is a 13-digit barcode used globally, though both are widely accepted by retail scanners worldwide.

Are the barcodes generated by this tool scannable?

Yes, this tool creates high-resolution, industry-standard barcodes that scan perfectly with any standard laser or smartphone camera scanner. We recommend printing them at a high resolution to ensure maximum readability.

What image format should I use to print my barcodes?

For the best printing results without any quality loss, you should download your barcodes in SVG or PNG format. Vector formats like SVG guarantee that the barcode remains crisp and scannable regardless of the label size.

What is a CODE128 barcode used for?

CODE128 is a highly versatile barcode format used primarily for shipping, packaging, and logistics because it can encode both numbers and letters. It is often used in supply chain management to track packages and inventory.
