MPN [mpn]

Use the MPN [mpn] attribute to submit your product’s Manufacturer Part Number (MPN). MPNs are used to uniquely identify a specific product among all products from the same manufacturer. Customers might search specifically for an MPN, so providing the MPN can help ensure that your product is shown in relevant situations.

Minimum requirements

When you submit product identifiers, we can better understand your products, connect customers to your products' ads, and make those ads richer. Learn more about product identifier attributes.
Distinguish between variants: Make sure you use the correct MPN for each product. Usually, each variant of a product (For example, different colors or sizes) has its own MPN, so make sure to submit the correct value. Note: An exception is when apparel products have the same MPN. In this case, do not submit any MPNs in Manufacturer Center.
