When setting up payments, I remember putting in my EIN, which at the time was my SSN. Since then, I have set up an EIN, and wanted to update that information but can’t find where to do so. How do I do this?
I recommend you to email directly to Shopify’s Merchant/Technical support. They should assist you with the issue!
