Hank here from Shopify.
Can you tell me a bit more about what you are trying to do?
Is it a case you need to obtain an EIN, or is it relating to something else?
Let me know if you need any additional help with this!
Okay, so can you confirm have you a banner within your Shopify admin, or are you needing to update your EIN within your store for tax reasons?
In order to update tax details, we require federal documentation to support the change. This can be in the form of a Signed and dated W9, SS4, or a CP 575 form. The documentation should include your EIN, address, and legal business name.
If this is correct, once I authenticate your store, I can then forward this ticket to my colleagues in escalated support who will add an upload button to your Shopify admin in order to provide this document.
Let me know if this is needed, or if it is relating to something else.
