Welcome to the growing family of QuickBooks Community, joseayerza.
SSN is required in connecting your bank account to Merchant Services. Since you've mentioned that you don't have one, I recommend contacting our Customer Care Team. This way, they can provide you other options in linking your account.
You can refer to this article to connect with our supports: Contact Payments Support.
Don't hesitate to tap the Community if you have any other questions about QuickBooks. We're always glad to help.
