Who is the publisher?
With a Basic Publishing Package, Phlint, Inc. is listed as the publisher of record for your ISBN. You keep the copyright to your work. If you need your own company listed as publisher, you'll need ISBNs registered to that company instead.
Frequently asked questions
Do I need a separate ISBN for each format?
Yes. Paperback, hardcover and ebook editions each need their own ISBN.
Who owns the ISBN?
ISBNs are identifiers, not property. The ISBN is assigned to your book under Phlint, Inc. as publisher of record and can't be transferred or reassigned.
Can I use it on Amazon?
Many authors do. Each sales channel sets its own ISBN and listing rules, so check the requirements of the channel you plan to use.
Can I get a refund?
Unused ISBNs may be refundable per our refund policy. Once an ISBN is registered to your book, it can't be reversed.
Are you the official ISBN agency?
No. ISBN.help is an independent service from Phlint, Inc. and is not affiliated with Bowker.
