Are the ISBNs supported by IngramSpark?

No. IngramSpark does not accept ISBNs assigned by third-party providers like us. This is an IngramSpark policy, not a limitation of the ISBN itself. Our ISBNs are valid, registered with Bowker, and work on all major platforms.

If IngramSpark is essential for your distribution, you'll need to purchase an ISBN directly at the national ISBN agency in your country of residence. For the United States, this is Bowker.

Looking for alternatives that connect to the Ingram network? Platforms like Lulu and PublishDrive use Ingram (the same network as IngramSpark) for distribution and do accept all ISBNs.
