Independent publishers and authors are responsible for acquiring ISBNs or EANs for their books.
An ISBN (International Standard Book Number), also known as EAN (European Article Number), is a unique thirteen-digit item code provided by your country’s ISBN agency and assigned by publishers to identify the format and edition of a particular title. A published book will have a different ISBN or EAN for each product type—one for the hardcover edition, one for the paperback edition, and one for the digital/ebook edition. Retailers and distributors require published titles to have an ISBN/EAN assigned to them for sales and inventory purposes.
The 978 prefix is a three-digit number to make the title EAN (European Article Number) compliant. This prefix is required to ensure the continued capacity of the ISBN system.
If you input a 10 digit number we will automatically convert your ISBN to 13 digits. In doing so, the last digit (check digit) will be recalculated using a specific algorithm. The two numbers correspond to each other and are considered the same ISBN, not a different one.
- From Bowker, the US ISBN Agency (www.myidentifiers.com). Check their website for current pricing.
- Through your IngramSpark account, for $85 each, when setting up your book and you own the ISBN. ISBNs purchased through IngramSpark are non-refundable.
- ISBN cannot be transferred to another account in the future
- ISBN cannot be used on any other publishing platforms (KDP, Blurb, Bookbaby, etc.)
- Pricing for at least one market is required and the book will be available for sale through each market pricing is provided for
- If you use a free ISBN and later decide you want to own the ISBN, you will have to set up the book as a new or revised title and purchase a different ISBN for the book
If located outside the United States you can visit https://www.isbn-international.org/ to find out where to purchase an ISBN or EAN.
SKU (stock keeping unit) is an identification code, usually alphanumeric, of a product that allows it to be tracked for inventory purposes. If you don't want your book available for sale through Ingram's global distribution network, IngramSpark can assign a free inventory code (SKU) to your book for printing and manufacturing purposes. When setting up your title you can select “Click here if you would like a non-distributable SKU to be assigned to this title”.
Be sure to use the same ISBN/EAN for your book in all markets. Listing the same book with different ISBNs or EANs on multiple websites or with multiple distributors may confuse retailers and consumers wanting to purchase your book.
You will also need to upload the cover and interior files. You can then have IngramSpark Support cancel the title with the SKU, if you wish.
