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:
What is GTIN
Global Trade Item Number (GTIN) is a unique and internationally recognized identifier for a product.
There are different GTIN formats depending on a region and product type. Here are the different GTINs you might encounter:
- UPC (in North America / GTIN-12): 12-digit number (8-digit UPC-E codes should be converted to 12-digit UPC-A codes)
- EAN (in Europe / GTIN-13): 13-digit number
- 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.
If your shopping cart system doesn't allow you to easily add GTINs to your products we can do it for you in DataFeedWatch.
If you would like us to add GTINs to your products please create a csv file with the following columns:

and send it to us, along with the shop name and a channel name.
