Personally I take the opposite approach, why not connect SSN numbers to everything?<p>As you mention, it&#x27;s easily determinable, and it has the fortune of being an existing ID number system already connected to everyone.<p>Allowing everyone the ability to tell people apart based on a number is infinitely better than matching names.<p>In my country we use our ID numbers for everything, dentist appointments, vehicle inspections.. if you call any business at all it will likely be one of the first things you&#x27;re asked for.<p>The number should be an identifier for a person, not a security measure.  If you just accepted the fact that SSNs are insecure and that by knowing someone&#x27;s SSN does not necessarily mean you are that person, then the US could use them more effectively, cut down on a significant number of errors in every industry, and actually reduce identity theft.
