  1. What is an ISBN barcode?

An ISBN barcode is a 13-digit code that is used to identify your book among thousands of others.

An International Standard Book Number, or ISBN, is basically an identification number code that allows book dealers, publishers, or libraries to regulate and locate specific titles.

Here is what it looks like:

You’ll notice that there are sections of numbers separated by a hyphen. These sections represent a particular element, which are:

     • Prefix – This element is always three digits, and can only be either 978 or 979.

     • Registration Group – this element refers to the geographical region, language area, or country engaged in the ISBN system. It varies between 1-5 digits.

     • Registrant – This element can go up to 7 digits, and it distinguishes the particular imprint or publisher.

     • Publication – This element identifies the format of your title as well as the edition. The digits can go up from 2-6.

     • Check digit – This single number validates the rest of the numbers in your ISBN. It has alternate weights of 1 and 3 and is calculated with the help of a Modulus 10 system.

  1. What is the difference between an ISBN and an ISBN barcode?

A barcode and ISBN are two different things. Don’t be confused by this just because you can find the ISBN at the top of the barcode of any book.

A barcode can still change, while a book’s ISBN may not. Also, the barcode contains other information such as the price of the book, and what currency it uses.

Usually, book distributors and retailers utilize the barcode for inventory and retail purposes.

  1. What is a book retail price?

Aside from your ISBN barcode, there is an optional price add-on code that allows book retailers to know the price of your book when scanned.

The retail price shows up as a smaller barcode to the right of your ISBN barcode. If you do not want the retail price add-on code to show next to your ISBN barcode, then leave these fields blank.

  1. What is the barcode color option?

The barcode color option controls the color of both the text on the barcode and the barcode itself. Barcodes are traditionally black, but they can be printed and scanned in other colors. Find your color preference in the selector and then press “OK.”

  1. What is the font and text size options?

The barcode generator allows you to select the font and text size for your barcode. To edit these attributes, choose your preference from the two drop-down menus. 9pt font size is the standard used in most barcodes.

  1. Can you generate ISBN barcodes to other countries?

Our ISBN barcode generator can create barcodes registered in all countries. However, we are only able to validate the accuracy of numbers registered in the United States, Britain, Canada, France, Israel, and Singapore.

All this means is that if you enter a code registered in another country, you need to make sure that you enter your ISBN number exactly as it was given to you, which also includes hyphenation. If you enter the numbers and hyphenation correctly, will then your barcode be created successfully.

  1. Where do I get an ISBN Number?

To create an ISBN barcode, you need to first purchase your 13-digit ISBN number. ISBN numbers are a series of thirteen numbers separated by hyphens. If you do not yet have an ISBN number, you will need to purchase one from Bowker or Nielsen.

  1. How much will I pay per one ISBN?

In the US, purchasing an ISBN costs about $125 per number. However, if you plan on buying in bulk, you get a significant discount.

Getting an ISBN is different in other countries. In the UK, its residents only pay about 89 pounds per number. In Australia, the price varies from $40, and in South Africa and Canada, their governments can issue an ISBN for their residents.

  1. Do I need an ISBN for every format of my book?

Yes. If you plan on creating and selling your book in different formats, such as print, audiobook, or eBook, then it is essential to get an ISBN for each of them.

  1. I only plan to sell my book on Amazon as an ebook. Will I still need an ISBN?

If you only plan to sell your ebook on Amazon and no other distributing channels, then you don’t need to get an ISBN. Amazon has its own code called ASIN, and they assign it to manage and track your book.

  1. I plan to sell my book internationally. Do I need to get one for every country I want to market?

No. Although an ISBN is assigned locally, you can use it internationally. Even though your distributor or publisher is US-based, they can still sell your books worldwide.

  1. Why do I keep getting the error: “It looks like the ISBN number you entered could not generate a valid barcode?”

You most likely received this error for one of the following reasons:

• The ISBN number was entered without hyphenation (all ISBN numbers must be hyphenated to generate correctly.)

• Characters were entered other than numbers and dashes (letters or special characters are not allowed in valid ISBN numbers.)

• Your ISBN number was not the expected length (valid ISBN numbers are always 13 digits.)
