Simple pricing, bigger savings per book
Every format of a book (paperback, hardcover, audiobook) needs its own ISBN, so most authors buy two or three. The discount applies automatically at checkout.

Who is listed as the publisher?
Our ISBNs are registered with Bowker under the publisher name Independent Publishing House. That listing is administrative: you remain the author and copyright owner, your name goes on the cover and on every store listing, and you keep all royalties.
When a retailer asks for an imprint or publisher name to match the ISBN (Amazon KDP does), enter Independent Publishing House. If you would rather have your own company name on the ISBN record, Bowker sells those directly for $125 per ISBN.
Frequently asked questions
Are these ISBNs accepted by Amazon KDP and IngramSpark?
Yes. They are genuine ISBN-13 numbers from the U.S. ISBN Agency and work with Amazon KDP, IngramSpark, Barnes & Noble Press, Apple Books, Kobo, Lulu, Draft2Digital and offset or local printers. When KDP asks for the imprint, enter Independent Publishing House.
How many ISBNs do I need?
One per format and edition. A paperback, a hardcover and an audiobook of the same book are three ISBNs. An ebook sold only on Amazon does not need one (Amazon uses its own ASIN), but most other ebook stores accept or require an ISBN. A revised edition with substantial changes needs a new ISBN; fixing typos does not.
What exactly do I receive?
Your 13-digit ISBN and its barcode as PNG, JPG, PDF and TIFF files, delivered by email within minutes and available any time under Downloads in your account. Hand the PDF or TIFF to your cover designer, or place the PNG yourself.
Who is listed as the publisher, and can I use my own imprint name?
The ISBN is registered to Independent Publishing House. You are free to put your own name or imprint on the cover and in your marketing. Where a platform requires the imprint to match the ISBN registration, use Independent Publishing House. Only Bowker can register an ISBN under your own company name, at $125 for one.
Do the ISBNs expire or have renewal fees?
No. It is a one-time purchase. An ISBN you have not used yet can be assigned to a future title or edition whenever you are ready.
Is the barcode the right size for my cover?
Yes. The barcode is supplied at standard book-industry size with the ISBN printed above the bars. Keep it black on a white or light background and do not stretch it in one direction. If you need a specific size or a price add-on, our support team will prepare it for you.
How fast is delivery?
Files are generated and emailed automatically as soon as your payment clears, usually within a couple of minutes. Check your spam folder if you do not see them, or download them from your account.
What if I change my mind?
Every order is covered by a 30-day money-back guarantee. Contact us and we will refund you.
