Hello, @blueturfconcrete.

Currently, only one debit account can be issued per Checking account. You can contact the Greendot support team with further inquiries, as they can securely provide you with the appropriate assistance and information.
I'm adding this helpful article to learn more about QuickBooks Checking account: Get all the details about QuickBooks Checking and envelopes.
