Find out if your item qualifies for an ISBN. Generally, books and electronic products like ebooks and audiobooks are eligible for ISBNs. Music CDs and other electronic products intended for entertainment do not qualify for ISBNs.
Decide how many ISBN numbers you need. The minimum order is 10 ISBNs. You cannot purchase a single number. However, since one ISBN is used for each edition of a book, you probably need several ISBNs. For example, if you are producing one hardcover, one softcover and one ebook edition, you need three ISBNs.
Read the guidance notes carefully, then fill out the four-page application. Mail the application with a copy of the title page and title page verso of your first publication, as well as a check made out to ISBN Agency or your credit card information.
