What are UPCs,
EANs, ISBNs. and ASINs?
Universal Product Code (UPC) is a 12-digit bar code used extensively for retail
packaging in United States.
The European Article Number (EAN) is a barcode standard, a 12- or 13-digit
product identification code. Each EAN uniquely identifies the product,
manufacturer, and its attributes; typically, the EAN is printed on a product
label or packaging as a bar code. We require EAN codes to improve quality of
search results and the quality of the catalog as a whole. You can obtain EANs
from the manufacturer. If your products do not have manufacturer EANs, and you
need to buy EAN codes, you; should go directly to GS1 UK [please contact me for website address]
For example, the EAN of
"Colgate Total 75 ml" is 4011200296908
The International Standard Book Number (ISBN) is a unique commercial book
identifier barcode. Each ISBN code identifies uniquely a book. ISBN have either
10 or 13 digits. All ISBN assigned after 1 Jan 2007 have 13 digits. Typically,
the ISBN is printed on the back cover of the book.
For example, the ISBN code for J.K.Rowling's "Harry Potter and the Deathly
Hallows", Adult Edition, Paperback, UK edition is 978-0747595823, and this
code identifies uniquely this book and edition.
Amazon Standard Identification Numbers (ASINs) are unique blocks of 10 letters
and/or numbers that identify items. You can find the ASIN on the item's product
information page at Amazon.com. For books, the ASIN is the same as the ISBN
number, but for all other products a new ASIN is created when the item is
uploaded to our catalogue. You will find an item's ASIN on the product detail
page alongside further details relating to the item, which may include
information such as size, number of pages (if it's a book) or number of discs
(if it's a CD).
ASINs can be used to search for items in our catalogue. If you know the ASIN or
ISBN of the item you are looking for, simply type it into the search box (which
can be found near the top of most pages), hit the "Go" button and, if
the item is listed in our catalogue, it will appear in your search results.
For example, the ASIN for Hasbro's "Monopoly" game is B00005N5PF.
