ISBN Barcode + QR Code Generator
Make a print-ready barcode and QR code for your book's back cover in seconds, sharp at any print size. Free, no signup.
Publishing only on Amazon with the free KDP ISBN? KDP adds the barcode for you when you leave the white space on the back cover, so you can skip this tool. Use it when you have your own ISBN, or you're printing through IngramSpark or expanded distribution.
Your ISBN
Do you need an ISBN?
KDP gives you a free ISBN for paperback and hardcover. That ISBN is tied to Amazon — you can't use it on other platforms. If you only sell on Amazon, the free ISBN is fine.
Buy a Bowker ISBN ($125 each, $295 for 10 in the US) if you plan to publish through IngramSpark, Draft2Digital, or your own store, or if you want the publisher of record to be your own imprint instead of "Independently published."
The barcode goes on the bottom-right of the back cover at 2.0″ × 1.2″ (100% magnification). KDP places it at least 0.76″ from the bottom edge and 0.25″ from the spine hinge. SVG output here scales to any DPI without loss, and includes the light quiet-zone margins scanners need.
The QR code is optional marketing, not part of the KDP barcode spec. Add it if you want a quick scan-to-buy link on the cover, or leave it off.
Frequently asked questions
Is the free KDP ISBN really free?
Yes. KDP assigns you a free ISBN at publication if you choose to use it. The catch is it's locked to Amazon — you can't use the same ISBN on IngramSpark or Draft2Digital. If you might expand distribution later, buying your own ISBN now avoids re-registering the book.
Where does the barcode go on the cover?
Bottom-right of the back cover, on a white background, at 2.0″ × 1.2″ (100% magnification). KDP places it at least 0.76″ from the bottom edge and 0.25″ from the spine hinge. (The 0.125″ figure some guides cite is the cover bleed, not a barcode quiet zone.) The generated SVG already includes the light quiet-zone margins on each side that scanners need.
Is the QR code required?
No. The QR code is optional marketing, not part of the KDP barcode spec. Most authors point it at their Amazon listing so readers can scan-to-buy, but you can override it with any URL — your author website, a review page, a special offer — or skip it entirely.
Is the SVG output really print-ready?
SVG is a vector format — it scales to any resolution without loss. When you import the SVG into your cover design tool (or print it at any size), it'll be sharp at any DPI. There's no need for a separate 300 DPI raster export.
