ISBN Assignments from the US ISBN Agency

What is an ISBN and how is it used?

ISBN stands for “International Standard Book Number”. It is a unique identifier for books, eBooks, tapes, and CD’s. The ISBN numbering system is used worldwide and publishers around the globe identify their work in this standardized format. Each title or edition must be identified by a unique ISBN. In essence, the ISBN number for books is similar to a license plate which guarantees that each book type product is identified uniquely.

Do books need ISBNs?

From the point of view of the international ISBN system there is no legal requirement to have an ISBN and it conveys no legal or copyright protection. However, both brick/mortar and online book sellers in the US require ISBN identification.  This unique identifier enables your book to be discovered since it will be posted in the global book database.


What is the Bookland EAN barcode?

Retailers and distributors require book products to carry a barcode which encodes the ISBN and pricing information. The Bookland EAN barcode is a standardized format which is accepted by trading partners worldwide. Our experience with barcodes enables us to provide our customers with symbols which comply with the GS1 guidelines and offer assistance with providing the appropriate format.  Please note, a digital barcode is not needed on ebooks.

If you require only a Bookland EAN symbol, we encourage you to purchase ISBN Bookland barcode files from for only $10 each.

Are there Unauthorized Resellers of ISBNs?

Unfortunately, there are a few internet companies which prey on new self-publishers. Since the ISBN assignment uniquely identifies a title for the life of the book, authors need to be assured of the legitimacy and security of the assigning company. There is even a company which calls itself, and they are not Bowker.

A key part of the ISBN assignment process is REGISTERING book information and cover art within the Global Books In Print Database. This function enables book discoverability. Publisher Services clients get to enter upload their title information and cover art through our online portal which automatically uploads to the master database. Without this assurance, you might just be receiving an arbitrary number. In addition, be wary of any company offering 30 day money back guarantees with ISBN purchases. ISBN numbers should NEVER be reassigned!
