Your Organization ID (OID) is an identifying number unique to your ENERGY STAR partnership that is used by certification bodies to submit certified product data to EPA. You can find your OID in your My ENERGY STAR Account (MESA) from the "My Organization Information" header. Your Org ID is listed under the details tab after you click on the organization. You can login into your MESA from https://energystar.gov/mesa.
Please note that your organization ID is also listed in the EPA partner directory available on our partner resources page https://energystar.gov/partner_resources. After searching for your company, you will see the ID listed next to it.
