Frequently asked questions

What is EAN-13?

EAN-13 (European Article Number) is a 13-digit barcode standard used worldwide for retail products. The last digit is a check digit, often calculated automatically. It is the most common format for consumer goods.

What is the difference between EAN-13 and UPC-A?

UPC-A is 12 digits and is mainly used in North America. EAN-13 is 13 digits and used globally; it is compatible with UPC by adding a leading zero. Many systems accept both.

Do I need a GS1 prefix to create barcodes?

For selling in major retailers and marketplaces (e.g. Amazon, Walmart), you typically need a GS1-issued company prefix and unique GTINs. For internal use, testing or small-scale sales, you can generate barcodes with our tool — check your retailer’s requirements.

Is the barcode generator free?

Yes. QR TheCode² offers free barcode generation. Account creation gives you more barcodes, product management and bulk export. Check the pricing page for plan limits.

Can I add barcodes to my product labels?
