|ISBN and UPC product code information|
If you have a book or product to sell in retail, you will need a unique identifier.
ISBN FOR BOOKS
Bowker is the official source for ISBNs in the United States. Visit ISBN.org for more information.
An ISBN uniquely identifies your book, and facilitates the sale of your book to bookstores (physical and digital) and libraries. Using ISBNs allows you to better manage your book's metadata, and ensure maximum discoverability of your book. Your book is listed in Bowker Books in Print®, which is used by all the major search engines and most bookstores and libraries.
You can go to My Identifiers to get your ISBNs instantly.
UPC FOR PRODUCTS (non-books)
GS1 is the official source for UPC codes. To sell your product in a store or online, you could be looking for a barcode, a GS1 Company Prefix, a Global Trade Item Number® (GTIN®), a U.P.C., or a GTIN-14. Visit gs1us.org for more information.
