There is some indication that the 979 numbers will work with KDP publishing. It may be that it's JUST going from Ingram to Amazon. Ingram only gives 13-digit numbers because it can't convert to 10-digit without duplicating a 978-10-digit number. Several people are testing whether the 979 will work with KDP. Stay tuned and keep and ear out.

Hi Darcy, several of our clients have published their books with the 979 prefix, using both IngramSpark and KDP, and no issues at all so far. We've also used the 979 prefix to get an LCCN. Again, no issues with the Library of Congress. Perhaps there is a unique set of circumstances that are causing problems?

I believe things like this are revealed to be resolved. Thank you for mentoring us thru this maze! I have 10/979 #s. I was on target to launch 3 books next yr/one every 30 days/to stay in amazon's "new release" window for 90 days. On to Plan B . . ."Blessed are the flexible because we will not be bent out of shape." Appreciate all you do!

I heard of this issue earlier this week and honestly, I’m devastated! My book is set to launch 5/17 after over 6 months of marketing. What’s a girl to do! 😩

Thank you for the heads up. This will affect so many who are not in the know. Seems counter-productive to Amazon's bottom line and therefore surprising they didn't get ahead of this.

I literally bought 10 ISBNs yesterday ($295) - all 979s. I'm crushed! But thank you for this post - forewarned is forearmed. I'll throw my tiny complaint at mighty Amazon and hope lots of others do as well.
