A friend of mine has asked me for the meaning of ASIN and the number that follows this acronym.
At this point I believe almost everyone knows that ISBN stands for International Standard Book Number. An ISBN is a unique number that identifies a book. Every book is assigned a unique ISBN-10 and ISBN-13 when published. The ISBN is 13 digits long if assigned on or after 1 January 2007, and 10 digits long if assigned before 2007.
The Amazon Standard Identification Number (ASIN) is a 10-character alphanumeric unique identifier assigned by Amazon.com and its partners for product identification within the Amazon organization.
I hope it has been of your interest
