mpn: Definition

When to use

Required for all products without a manufacturer-assigned GTIN. Learn about the gtin attribute.

If the product doesn’t have a clearly associated mpn or is a custom-made product (e.g., art, custom t-shirts, novelty products, and handmade products), the attribute is optional.

• Distinguish between variants.
  • Use the correct MPN for each product. Typically, each variant of a product (different colors or sizes) has its own MPN, so make sure to submit the correct value. A key exception is different sizes of apparel products, where all sizes often have the same MPN.
