Find a GTIN

A custom icon for Merchant Center Classic and Merchant Center Next.

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 [gtin] attribute to help us classify and display your products.

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

Finding a GTIN

To find the GTIN of your product, you can refer to the barcode on your product, 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. Keep in mind that not all products have a GTIN. If you can't find the GTIN, you can always contact the product's manufacturer to ask for it. Learn more about unique product identifiers
