You can see that the number is divided into 4 combinations. But only three of them are useful. The first digit 0 is just the initial number.

  • 0 is basically the language group identifier. In this case, it indicates English.
  • The next 6 digits are the publisher identifier.
  • The next two digits are the title identifier. This is assigned by the publisher himself to a specific edition or particular book.
  • The last single digit is the check digit which is calculated mathematically. This helps in assuring that the rest of the ISBN has been scanned or recorded accurately.

Since 2007, the new format of 13 digits has been introduced. You need to apply the same process to read it. The only difference is that it adds 978 at the beginning which identifies the following series of numbers as an ISBN.

The difference between ASIN and ISBN

In order to understand the difference between ASIN and ISBN, you need to understand what they are used for.

ASIN stands for Amazon Standard Identification Number which is known to consist of a unique combination of 10 numbers or letters. It is used to easily identify items. Every time a new product is uploaded on the Amazon site, a new ASIN is assigned to the product. If you check the product detail page, you can find the ASIN number. The ASIN number is known to vary if the product is sold in the US and other marketplaces.

On the other hand, ISBN stands for International Standard Book Numbers. This is used as a unique identifier by commercial books along with a barcode. Every book that you read comes with an ISBN number which comprises of 10 or 13 digits. You can find the ISBN number on the back of the book cover. Books do not have ASIN numbers.

From the above distinction, it is clear that ASIN and ISBN are different formats but they serve the same purpose for a product.
