Find the Right ISBN for Your Book

What's an ISBN?

An ISBN, or International Standard Book Number, is a unique 10- or 13-digit number assigned to every published book. An ISBN identifies a title's edition, publisher, and physical properties such as trim size, page count, and binding type.

How are ISBNs used?

Bookstores, retailers, and libraries identify books by their ISBNs. We print an ISBN barcode on the lower back right corner of every book we manufacture.

What are my ISBN options?

You have four ISBN options: you can either use a CreateSpace-Assigned ISBN, a Custom ISBN*, a Custom Universal ISBN*, or you can use your own ISBN. Both custom ISBN options are offered through an agreement with Bowker®.

Imprint of Record

Think of the imprint as a "brand name" for a particular line of books, like classic literature or children's books. Most major publishers have various imprints. If you are not using a CreateSpace-assigned ISBN, you can manage your imprint information that's available to vendors via myidentifiers.com
