A Global Trade Item Number (GTIN) is a unique and internationally recognized identifier for a product. When a GTIN is available, it will appear next to the barcode on your product's packaging or book cover. Submit GTINs in your product data using the 'gtin' attribute to help us classify and display your products in Shopping ads.
Types of GTINs
GTINs vary in length depending on the type of product and where the product will be sold. 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
