Title: MPN missing from Google Schema Last modified: February 2, 2020 --- # MPN missing from Google Schema * Resolved [administratus](https://wordpress.org/support/users/administratus/) * (@administratus) * [6 years, 4 months ago](https://wordpress.org/support/topic/mpn-missing-from-google-schema/) * Hello, * Google was giving me a warning that all products in my store miss the GTIN and MPN. They are individaul products, so they don’t have either. To get rid of the warning anyway, I have assigned an individual MPN to every single product. Now I am quite disappointed because the Google warning still persists :/ When I look into the HTML code of a product-page then I can find the SKU and all the other assigned schemata-data, but the MPN doesn’t show up. * Does anyone has any idea how to fix this? * I found this code here, which should assign the SKU-value as MPN and hence resolve the warning. But I am not sure how to implement it correctly: [https://shanerutter.co.uk/fix-for-woocommerce-schema-data-missing-brand-and-mpn/](https://shanerutter.co.uk/fix-for-woocommerce-schema-data-missing-brand-and-mpn/) * Thanks for any replies! * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fmpn-missing-from-google-schema%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 6 replies - 1 through 6 (of 6 total) * [Mike W](https://wordpress.org/support/users/nixiack8/) * (@nixiack8) * [6 years, 3 months ago](https://wordpress.org/support/topic/mpn-missing-from-google-schema/#post-12476167) * Hi there! * With Google reporting that it is missing the GTIN and MPN, you will need to double check the products’ settings. More on this is in the [documentation](https://docs.woocommerce.com/document/google-product-feed-troubleshooting/#section-3) of Google Product Feed. * Please check it out and follow the steps.

The link you posted should resolve the issue– HOWEVER unfortunately i am lost in the WooCommerce settings 🙁 * WooCommerce » Settings » Product Feeds simply does not exist in my backend! In WooCommerce » Settings I find a tab lables “Products”. This one has 3 more sub- tabs – “General”, “Stock” and “Downloadable Products” , but there are no settings regarding the MPN or GTIN there. * My WordPress is in German and I am using a plugin called Germanized which is essential to adjust the store to European laws. In the Germanized-settings there is nothing about the MPN either. And the plugin shouldn’t remove other settings entirely… * Any idea why the tab could be missing? * Plugin Support [John Coy a11n](https://wordpress.org/support/users/johndcoy/) * (@johndcoy) * Automattic Happiness Engineer * [6 years, 3 months ago](https://wordpress.org/support/topic/mpn-missing-from-google-schema/#post-12478985) * Hi [@administratus](https://wordpress.org/support/users/administratus/) * There are no MPN settings by default. The documentation above is for a paid plugin called Google Product Feed: * [https://woocommerce.com/products/google-product-feed/](https://woocommerce.com/products/google-product-feed/) * Thread Starter [administratus](https://wordpress.org/support/users/administratus/) * (@administratus) * [6 years, 3 months ago](https://wordpress.org/support/topic/mpn-missing-from-google-schema/#post-12479301) * Thanks, John! I already realized that 🙈 * If I assigned an MPN to the individual products, it should show up in the code without buying an additional plugin, right? sku and the other parameters work just fine since the WooCommerce Update in November fixed some schema errors caused by a previous update. only the MPN doesn’t get delivered and i don’t understand why. * Plugin Support [John Coy a11n](https://wordpress.org/support/users/johndcoy/) * (@johndcoy) * Automattic Happiness Engineer * [6 years, 3 months ago](https://wordpress.org/support/topic/mpn-missing-from-google-schema/#post-12479739) * Hi [@administratus](https://wordpress.org/support/users/administratus/) * > If I assigned an MPN to the individual products, it should show up in the code > without buying an additional plugin, right? * If you have a way to assign an MPN then I’d would assume so. You may just need to contact the developers that added that field to the products. I see that others have used this plugin to get it done: * [https://github.com/Auke1810/woocommerce-additional-product-identifiers](https://github.com/Auke1810/woocommerce-additional-product-identifiers) * Since there is no way to assign the MPN by default in core, I’ll mark this thread as resolved. * Thread Starter [administratus](https://wordpress.org/support/users/administratus/) * (@administratus) * [6 years, 3 months ago](https://wordpress.org/support/topic/mpn-missing-from-google-schema/#post-12479837) * Thanks! So that means that I have an active plugin creating the MPN field? I checked the entire list of plugins and couldn’t identify anything that might be causing it. * Are you sure that WooCommerce doesn’t create an MPN field by itself? ([see screenshot](https://imgur.com/a/5A1CMSL)) Then i might consider tracing the problem to the Germanized plugin, which is the only active plugin i could imagine could create the MPN field. - This reply was modified 6 years, 3 months ago by [administratus](https://wordpress.org/support/users/administratus/).
