Amazon barcode rules, including UPC versus FNSKU, are covered in our Amazon barcode guide.

A few good questions

Are these barcode tools really free to use?

Yes. Every tool on this page is completely free. There is no account required, no trial period, and no hidden cost. If you need actual UPC or EAN barcodes to sell products, those are available separately through our barcode packages.

Do the tools store or share any of my data?

Many tools do their work right in your browser. Product lookups send the barcode or identifier you enter or scan to our lookup service to find a match.

Which barcode formats do these tools support?

UPC-A, UPC-E, EAN-13, EAN-8, Code 128, QR Code, and Amazon FNSKU. UPC is standard in the US and Canada; EAN-13 is used in most other markets.

What is the difference between UPC, EAN, GTIN, and FNSKU?

UPC (12 digits) and EAN (13 digits) identify products at retail. GTIN covers both. FNSKU is Amazon’s warehouse identifier. Most sellers need a UPC or EAN to list, then Amazon assigns an FNSKU.

How can Amazon sellers use these tools?

Count barcodes across variations, print FNSKU labels, look up ASINs from UPCs, and convert UPC-A and UPC-E. More detail is in the Amazon barcode guide.

Can I use the barcode generator to create barcodes I can sell with?

The bulk generator previews codes you already own. To sell on Amazon or in stores, source legitimate UPC or EAN numbers. Purchase barcodes from BarCodesTalk for instant delivery with no annual fees.

How do I know how many barcodes I need?

Each unique variation — size, color, flavor, or style — needs its own barcode. A shirt in three colors and four sizes needs 12 codes. Use the Quantity Calculator before you buy.

Can I create and scan QR codes for free?

Yes. QR Code Generator makes static codes for links, text, WiFi, and contacts. QR Code Scanner decodes with your camera or an uploaded image.

Do these tools work on mobile devices?

Yes. The scanner can use your phone camera for UPC, EAN, and QR codes. Label printing is more reliable on a desktop with a printer.
