Google Shopping does not require handmade items to include a UPC or GTIN in order to be published to their platform. We recommend selecting "Unbranded" or "Handmade" under the brand drop-down menu on the item edit page for any listings which are handmade.
Once you have updated the brand for your listings to "Unbranded" or "Handmade," be sure to click the green "Update booth" button on your "Selling > Add or edit items" page to resubmit the listing data to Google Shopping. It can take up to 72 hours for Google Shopping to review your listings and publish the items to their platform. After 72 hours, you can request a new feed status review.
Please note that any brand-name commodities in new condition must include a valid UPC in order to be published to Google Shopping.
