If you’re using your own ISBN and get an error message, asking you to “Please fix the highlighted issue” but you don’t see any fields highlighted, this typically means there’s an issue with your ISBN or imprint.

ISBN or imprint errors can occur in two scenarios:

1. There’s a spelling, spacing, or punctuation mistake. These fields are case-sensitive. All details must match exactly between KDP and the ISBN agency you used (e.g. Bowker).
   1. Solution: We recommend copying and pasting directly from the ISBN agency into KDP.
2. The title, author name, or imprint (i.e. publisher) don’t match between KDP and the ISBN agency.
   1. Solution: Go to the ISBN agency’s website and review the imprint name, title, and author associated with the ISBN. Verify the details match between KDP and them.

Tip: Most authors use Bowker. If you have questions about your ISBN metadata, you'll need to contact them.
