ISBN Validator
Enter an ISBN-10 or ISBN-13 to validate it.
What is an ISBN?
An ISBN (International Standard Book Number) is a unique numeric commercial book identifier based upon the 9-digit Standard Book Number (SBN).
ISBNs are used by publishers, booksellers, libraries, internet retailers and other supply chain participants for ordering, listing, sales records, and stock control purposes. The ISBN identifies the registrant as well as the specific title, edition and format.
Why is ISBN Validation Important?
ISBN validation ensures that the ISBN you are using is correct and follows the standard format. This is crucial for several reasons:
- Accurate Identification: A valid ISBN ensures that your book is correctly identified in databases and catalogs.
- Sales and Distribution: Retailers and distributors rely on valid ISBNs to process orders and manage inventory.
- Metadata Accuracy: A valid ISBN helps ensure that the correct metadata (title, author, publisher, etc.) is associated with your book.

Using our ISBNs is a better option than free ISBNs provided by self-publishing platforms like Amazon KDP because our ISBNs give you more control and potentially greater book exposure.
