Go to the ISBN Web site and go to “Order ISBNs”. Applications are available in English and Spanish. Click on the application information and you will have a page that gives you an option to apply for a single ISBN number or a block of ISBN numbers. You will prepare your application on a secure server if you submit online. You will need to enter your email address and re-type the address for verification. Once this information is entered, you will need to enter your credit card information.
Submit your application. Once it is processed, you will be emailed your ISBN numbers and your user name and password for Bowker Bar Code Service. This is the Web site where publishers request a bar code for the back of their book.
Prepare your book so it includes the ISBN on both the copyright page and the back cover.
