    Finding GTINs for your Products

    GTINs are required to list your product on Google (see earlier post), on Amazon Marketplace and an increasing number of shopping channels. Having the GTINs for your products is therefore increasingly important. Here's more information on the various types of GTINs and how to find them:

    • JAN (in Japan / GTIN-13): 8 or 13-digit number
    • ISBN (for books): 13-digit number (ISBN-10 values should be converted to ISBN-13)
    • ITF-14 (for multipacks / GTIN-14): 14-digit number

    Why do I need GTINs?

    Because of its worldwide recognition and common application GTIN numbers are the best possible unique identifiers of products.

    That is why many Shopping Engines and Marketplaces use GTINs to identify and compare the products that merchants send to them in their data feeds.

    A lot of those channels, like Amazon Marketplace and Google Shopping, require merchants to provide GTIN in their data feeds.


    How to find GTINs?

    Refer to the barcode on your product's packaging or book cover. Take a look at the example barcodes below to get a sense of how the GTIN can be displayed on your product. If you can't find the GTIN, you can always contact your supplier or the product's manufacturer to ask for it.

    You can also try finding GTINs for your products in the products open catalog or buy it online.

    To avoid adding GTINs one-by-one refer to the bulk product update help section of your shopping cart.
