I recently signed up for SS/Medicare over the phone, after filling out an online form. I didn't have to provide any paper proof of marriage certificate, no driver's license, etc. Just verification from my employer that I was, indeed, employed. Just mailed in a couple of signed forms! "Distanced" sign up — all due to Covid. Think of the millions of "refugees" that will be doing the same. I don't know how our system can survive it.
