Add your product's globally valid GTIN in the Shopify store.
GTIN (Global Trade Identification Number) is a unique identifier for a product.
When GTIN is added to your product, it will be displayed next to the barcode on your product's packaging. It helps in the classification of your products, matches your products with search queries, and helps in comparison against different merchants.
Why do I need a GTIN?
- Google Merchant Center will only approve products if you enter a valid GTIN for your products.
- However, not all products have GTIN available for them, like handcrafted, vintage, or not mass-manufactured.
- Correct GTINs help in matching your products with the search queries and help in increasing impressions and conversions.
- Any products with missing GTINs risk receiving lower priority in the listing.

How can I identify GTIN for my product?
There are various types of GTIN available, like UPC, EAN, JAN, ISBN, etc. To find the GTIN of your product, refer to the barcode of your product, for example, the product's packaging.
However, not all products have GTIN available for them. In this case, you can contact the product's manufacturer to ask for it. Additionally, you can also check ISBNdb.com or other GTIN databases for finding information about your products.
I do not have GTIN available for some of my products.
What can I do?
You can leave the GTIN field empty if you do not have it on. If the GTIN field is empty, AdNabu's app will send the GTIN as a 'null' value, ensuring your products are not disapproved by Google Merchant Center because of GTIN.
However, some of the products that are widely manufactured products are only displayed in Ads by Google if they have accurate GTINs associated with them. For these types of products, you must follow the above-mentioned steps.
