How to Get an ISBN for Your Self-Published Book

ISBN for self-publishing book printing If you’re wondering how to get an ISBN for your self-published book, InstantPublisher makes it easy. We are one of the few authorized ISBN resellers in the USA. Every ISBN purchase includes a free barcode, so your book is ready for retail.

Already have an ISBN and just need a barcode? We offer barcode-only services for just $15. This is perfect for authors who purchased their own ISBN elsewhere but still need a professional-quality barcode.

The International Standard Book Number (ISBN) is a 13-digit identifier that connects your book to global databases and booksellers. It’s required for retail distribution — including Amazon, bookstores, and libraries.

Whether you're printing paperback, hardcover, or spiral-bound books, we’ll help you purchase an ISBN that fits your publishing goals. Contact us with any questions.
