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. Users might search specifically for an MPN, so providing the MPN can help ensure that your product is shown in relevant situations.

When to use

Recommended for all products with a unique MPN.

Format

To make sure we understand the data you're submitting, follow these formatting guidelines:

Type	String (Unicode characters. Recommended: ASCII only)
Limits	Up to 1000 characters
Repeated field	No

File format	Example value
Text	`GO12345OOGLE`
XML feeds	`<g:mpn>GO12345OOGLE</g:mpn>`

Guidelines

Follow these guidelines to make sure you submit high-quality data for your products.

Minimum requirements

To make sure you submit high-quality data for your products, follow these minimum requirements. If your attribute is disapproved, we'll notify you in the Key Actions page of your Manufacturer Center account.

Submit all relevant unique product identifiers: You are required to submit the brand [brand] and gtin [gtin] attributes. 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 (e.g. 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.
