KDP Expanded Distribution vs Going Direct to IngramSpark

KDP Expanded Distribution and going direct to IngramSpark are two roads to the same goal: getting your print book beyond Amazon and into bookstores and libraries. Expanded Distribution is the simple, built-in option inside KDP that pushes your paperback into a wider catalog for you. Going direct to IngramSpark means opening a separate account and listing the book yourself through Ingram, the largest print distributor. Many authors do not choose one. They use KDP for Amazon and IngramSpark direct for everything else, and both paths are perfectly legitimate.

What KDP Expanded Distribution actually does

When you publish a paperback on KDP, you can tick a box for Expanded Distribution. This tells Amazon to make your book available to a wider network of retailers, wholesalers, libraries, and bookstores beyond Amazon's own store. It is convenient because it lives inside the account you already have, requires no extra upload, and costs nothing to enable. For a first-time author who wants a little more reach without managing a second platform, it is a reasonable starting point. The tradeoff is that you have less control over the wholesale discount and returnability, and because Amazon is routing the book to the trade on your behalf, bookstores are sometimes hesitant to order a title that lists a competitor as its source of supply.

What going direct to IngramSpark does

IngramSpark is Ingram's self-publishing arm, and Ingram is the catalog that physical bookstores, libraries, schools, and international retailers actually order from. Listing your book directly through IngramSpark puts it in that catalog on your terms. You set your own wholesale discount and decide whether the book is returnable, the two levers that most influence whether a bookshop will stock or special-order your title. Ingram's stated reach is tens of thousands of retailers and libraries. Title setup fees were eliminated in 2023, so opening a title no longer carries the upfront charge that older guides mention. The one firm requirement is that you bring your own ISBN.

The ISBN ownership question

This is the detail that quietly shapes everything else. KDP offers a free ISBN, and many authors use it for their Amazon paperback. A free KDP ISBN works only within KDP's system, including its Expanded Distribution, and it lists Amazon as the publisher of record rather than your own imprint. IngramSpark does not offer free ISBNs at all. To publish there you must own your ISBN, purchased in the US from Bowker at myidentifiers.com (verify current pricing before you buy). Owning your ISBN lists your imprint as the publisher, and it lets the same edition live on more than one platform under one identifier. If you think you may ever go wide, buying your own ISBN from the start keeps every door open.

Why many authors run both

Here is the pattern that has become common and works well. Publish the book on KDP for Amazon sales, because KDP prints and ships Amazon orders quickly and often at a lower print cost. Then publish the same book on IngramSpark for every other channel: bookstores, libraries, and international retailers. To avoid the two platforms competing to supply Amazon, authors typically leave Expanded Distribution turned off on KDP and let IngramSpark handle the wider trade, or they keep KDP for Amazon only and rely on Ingram for the rest. To do this cleanly you use your own ISBN on both, so it is genuinely one edition in two distribution systems, not two separate listings fighting each other.

Switching considerations

If you started with a free KDP ISBN and later want to go direct to IngramSpark, you cannot carry that free identifier over. You would create a new edition on Ingram with your own purchased ISBN. That is not a disaster, but it does mean the two listings have different identifiers, so plan for it rather than discover it. Whenever you list the same book in two places, keep the interior and cover files consistent, and remember that Ingram preflights print files against a stricter professional standard, so a file built to Ingram's specification will generally pass on KDP too. The reverse is not always true. Building to the higher standard once saves you a rebuild later.

A simple way to decide

If you only care about Amazon, KDP alone is plenty, and you can skip Expanded Distribution entirely. If you want light extra reach with zero added effort, Expanded Distribution is a fine box to tick. If bookstore and library availability matters to you, or you want your own imprint as the publisher of record, going direct to IngramSpark with your own ISBN is the stronger route, and pairing it with KDP for Amazon gives you the best of both. There is no wrong answer here, only the mix that fits your goals. Whichever you choose, professionally built files make the process smoother.

Frequently asked questions

Can I use KDP and IngramSpark for the same book at the same time?

Yes, and many authors do. Use KDP for Amazon and IngramSpark for the wider trade. The cleanest way is to publish with your own ISBN on both so it is one edition in two distribution systems. To avoid the platforms competing to supply Amazon, most authors leave KDP's Expanded Distribution off and let Ingram handle the other channels.

Does Expanded Distribution reach the same stores as IngramSpark?

There is overlap, because both ultimately touch the trade catalog, but going direct to IngramSpark gives you control over the wholesale discount and returnability that bookstores weigh when deciding to order. That control is the main reason authors who care about bookstore and library sales list directly through Ingram rather than relying on Expanded Distribution alone.

Do I need my own ISBN, or can I use the free one?

A free KDP ISBN works only inside KDP's system, including its Expanded Distribution. IngramSpark requires your own ISBN, purchased from Bowker in the US. If there is any chance you will go wide, buying your own ISBN from the start lets the same edition live on both platforms under one identifier and lists your imprint as the publisher.
