I am trying to register my EFIN with ProConnect Tax Online. To do this, I need my EFIN Summary. I can get this by going onto the IRS' E-Services. When I login to this system, it asks me to validate myself with a piece of financial information. All of my financial assets (credit card, auto loan , mortgage) is in my maiden name. I am now married. The EFIN is also under my married name. So providing this data with my maiden name won't reconcile with the name I used to get the EFIN. I can't call the IRS due to the government shutdown. 

Is there an alternative I can provide ProConnect Tax Online other than the EFIN Summary?
