No. Amazon KDP, IngramSpark, Draft2Digital and every other platform will publish your book without one. If you leave it blank or use a free platform ISBN, the listing simply shows the platform's default — "Independently published" on Amazon. A publisher name only becomes a real option once you own your own ISBNs.
The publisher field trips people up because it looks like a requirement and behaves like a preference.
What actually happens by default:
So the question is really: do I want the publisher line to say something specific? And the answer depends entirely on who is going to read it.
Most readers never look at the publisher field. It appears well down the product page, below the things that actually drive a purchase — cover, title, blurb, reviews, price, ranking. A first novel selling to genre readers on Amazon loses nothing to "Independently published."
If your entire plan is Amazon, and your budget is tight, spending $295 on ISBNs purely to control a field almost nobody reads is a poor use of the money. Spend it on the cover.
The mistake to avoid is buying one ISBN. A single novel across ebook, paperback and hardcover needs three. One at $125 versus ten at $295 is the worst value in self-publishing.
