Hey, @Davidal ! Welcome to Shopify Community!
While an SSN is mandatory to open a Shopify Payments account in the US, you can submit a request to use an EIN instead. We can’t guarantee this is possible, but we’d love to look into the possibility for you. In order for us to do so, we’ll need to access your account and relay your details to the appropriate team. We’re not able to provide account-specific support via the Shopify Community at this time, however, we’d be happy to continue assisting you through live chat, email, or callback. Please visit https://bit.ly/3cJkx8V and log in to your account to create a support request.
After visiting the link and logging in, you’ll be prompted to select the topic of your concern so we can connect you to the right articles and support team. Once you do, you’ll be able to find the options for support below the help docs that are presented to you.
Since this is the next step I’ve marked this reply as the solution for the benefit of others who may discover this topic. Thanks!
