When to use

Required for all products.

Several different types of ID numbers are considered a GTIN. Use the gtin [gtin] attribute to submit any of the following types of numbers: 

  • UPC (in North America / GTIN-12): 12-digit number (convert 8-digit UPC-E codes to 12-digit 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 (convert ISBN-10 to ISBN-13). If you have both, include only the 13-digit number. 
  • ITF-14 (for multipacks / GTIN-14): 14-digit number

Minimum requirements

These are the requirements you'll need to meet to upload data for your products. If you don't follow these requirements, we'll disapprove the product and let you know in the Diagnostics page of your Manufacturer Center account. 

  • Submit all relevant unique product identifiers. When you submit these product identifiers, we can better understand your products. When we understand your products, we can help connect users to your products' ads, and make those ads richer. Learn more about product identifier attributes
  • Submit a GTIN as defined in the official GS1 validation guide. Specifically, to meet the following requirements:
    • Make sure that the check digit is present and correct using the GS1 Check digit calculator.
    • Don’t submit a GTIN in the restricted ranges. Restricted ranges have the following prefixes: 02, 04, or 2.
    • Don’t submit a GTIN in the coupon ranges. Coupons have the following GS1 prefixes ranges: 98–99. 
    • Don’t submit a GTIN for a product that doesn’t have a GTIN. If you’re the only seller of a product or if your product is a store brand, it generally won’t have a GTIN. These products are not eligible for Manufacturer Center. 
  • Use the correct GTIN for each product, including variants. Each product and variant of a product (different colors or sizes) has its own GTIN, so make sure to submit the correct value. Duplicate GTINs will be rejected.
  • Do not submit bundles or multipacks that do not have their own GTINs. 
  • For compatible products, only include your product’s actual GTIN. Do not submit the GTIN of a compatible or similar product.

Additional guidelines

Review each section closely to determine if the requirements apply to your product. If you don't follow requirements that apply to you, we'll disapprove your product and let you know in the Diagnostics page of your Manufacturer Center account.

Books and media

  • Use the ISBN-13 of a book as the value for the gtin [gtin] attribute. 
  • For a product that has a UPC and an ISBN-13, submit the gtin [gtin] attribute twice, once for each value.
  • For a product with only an SBN (9 digits, used in Great Britain until 1974), convert it to an ISBN-10 by adding a 0 in front. For example, to convert 123456789, submit 0123456789.
