How to fix "the ISBN on your cover doesn't match"
Updated October 28, 2026 · IngramSpark · Amazon KDP
This one is easy to miss: the cover looks perfect, but the number on the barcode belongs to a different edition.
The error: “The ISBN on the cover does not match the ISBN of this title”
The ISBN on the cover does not match the ISBN of this title
Paraphrased. Each printer words this a little differently.
Quick fix: SparkPrep reads the ISBN on your cover, checks it against your book, and shows you exactly what to change.
Why you get “The ISBN on the cover does not match the ISBN of this title”
Every edition of a book has its own ISBN: the paperback, the hardcover and the ebook each get a different number. The barcode on your back cover has to carry the exact ISBN you entered for this edition.
It usually goes wrong when a cover is reused from another edition, or a barcode was made before the ISBN changed. The printer reads the barcode, sees a different number, and rejects the file.
How to fix “The ISBN on the cover does not match the ISBN of this title” manually (the hard way)
If you want to try adjusting the files yourself, here are the steps you need to follow:
- Look up the ISBN you entered for this exact edition in your KDP or IngramSpark book setup.
- Open your cover file and read the number printed above and below the barcode.
- If it's different, make a new barcode for the right ISBN (IngramSpark has a free barcode generator) or let KDP add its own barcode.
- Put the new barcode in the barcode area and re-export as PDF/X-1a:2001.
- Re-upload it to your printer and wait for the file review again. If it fails, you start over.
You can fix this by hand with the steps above. Or drop your file into SparkPrep and let it find the problem and fix it for you, in minutes. Try it on your file.

Quick answers
Can I use the same ISBN for my paperback and hardcover?
No. Each format needs its own ISBN, and the barcode on each cover must match that format's ISBN.
Does KDP add a barcode for me?
Yes. If you leave the barcode area empty, KDP adds its own barcode for the ISBN you entered.
