ISBN FAQ – Buying & Assigning Your ISBN

How do I buy an ISBN?

You can purchase ISBNs directly through our online store. We offer options such as:

Single ISBN
ISBN + Barcode bundle
Multi-ISBN packs for creators publishing multiple formats

What happens after I purchase an ISBN?

Once you buy an ISBN:

You’ll receive your unique ISBN number.
We'll assign it to one specific book format.
We'll register the book’s metadata (title, author, publisher, format).
The ISBN becomes permanently linked to that version of your book.

Can I reuse the same ISBN for multiple books?

No. Each ISBN is permanently tied to one book and one format.
For example:

Paperback = 1 ISBN
eBook = 1 ISBN
Hardcover = 1 ISBN

If you release a new edition or major update, you’ll need a new ISBN.

What is the ISBN assignment process?

Assigning an ISBN is simple:

Choose which book format the ISBN will be used for.
Enter your book details (title, subtitle, author, imprint).
Confirm the format (digital, print, audio).
Apply the ISBN to your cover file and metadata during publishing.

Once assigned, the ISBN cannot be changed or reassigned.

Do I need a barcode?

Print books sold in retail stores require a barcode version of your ISBN.
If you plan to sell physical copies through bookstores or wholesale channels, we recommend purchasing the ISBN + Barcode option.

What publishing name will show up?

It will be registered under East End Publishing LLC, which helps you look more established and professional.

Can I transfer an ISBN later?

ISBNs are not transferable once assigned. Always double-check your book details before finalizing the assignment.

Is buying multiple ISBNs better?

If you plan to publish across multiple formats or future projects, buying a bundle of ISBNs is usually more cost-effective and keeps your catalog organized.
