>That was likely someone not authorized to work in the US writing random digits on an I9 form.
I used to work a job years ago with lots of people who snuck in here. In order to get the job they needed to provide a social. Not having any idea wtf a social security number was, just that they needed one, it was a relief when someone they lived with or met on the street informed them that xyz at location abc will sell you one for $100.
That's one spot where the identity theft rubber meets the road. And practically everyone's social has been leaked by now.
Leaked? Isn't it used in the open basically like for everything including student IDs?
This was once common but is exceedingly rare these days. I'm sure exceptions exist, but nearly all Americans now treat this as a Very Secret Number.
I'm not sure people treat this as a Very Secret Number. Certainly using SSNs publically has gone away, but people are willing to provide their SSNs to basically anyone that asks for it. Heck, some job applications ask for your SSN.
LOL.
Every single $&@ doctor's intake form: "We'd like to have you SSN".
Yes, I have seen doctors and dentists ask for the SSN, and categorically refuse to provide it.
Unless you personally are nearly all Americans, good for you, but not relevant to OPs post about "Very Secret Number"
