Can you list my book with Nielsen instead of Bowker?

As an American company, ISBNdirect does not have access to Nielsen's database. We operate with Bowker for ISBN registrations. However, this doesn't limit the utility of your ISBN.

An ISBN from Bowker is recognized internationally and can be used effectively across various platforms and retailers globally. This wide acceptance ensures that your book can reach a broad audience, regardless of the database used for registration.
