>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?

[dandelany]

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.

Secret... But generatable since 2009. [0] 2011 randomisation slightly reduced the risk, but not by much.

As many as 1 in 7 SSNs may have been accidentally used by more than one person. [1]

Unlike Australia's TFN or the UK's VAT, SSN has no self-check, making it rather easy to just... Generate one that works.

And all an API check of the number will tell you, is what an attacker would already have: DOB and Place of Birth.

I don't think that they actually do in practice. Last time I opened an account with Comcast they required your social security number. Same with an AT&T cell plan.

Last time I opened an account with Comcast they required your social security number. Same with an AT&T cell plan.

Strictly speaking they require /a/ Social Security Number, not necessarily /your/ SSN.

When I signed up for my most recent cellular service, I hesitated at giving my information to the guy in the store. I told him that since it was a pre-paid account I wasn't asking for credit, so there's no need for him to have my information.

He was OK with that, and pulled out an ID card the store keeps in a drawer for just such occasions.

Salespeople have a sales quota, not an enforce-the-rules quota.

Same when I visited Germany, every phone account needs your name and address and passport number to prevent spam, I bought a prepaid card, since I don't live there I don't have an address, so he used the address of the store. Still needed a passport though.

I applied for my first credit card at a desk they had set up in front of the school. No SSN. When I entered my income (non existent), guy went "no man.. come on. put this amount. hey'll never give you a card with that". Week later I received the card with my name misspelled and everything. (I still see that misspelled name EVERYWHERE when I search for my name)

[dizhn]

Probably something to do with checking credit history right?

[vulcan01]

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.

*Super Secret Number

[groby_b]

LOL.

Every single $&@ doctor's intake form: "We'd like to have you SSN".

[drnick1]

Yes, I have seen doctors and dentists ask for the SSN, and categorically refuse to provide it.

[groby_b]

Unless you personally are nearly all Americans, good for you, but not relevant to OPs post about "Very Secret Number"

[rationalist]

And none of them have ever complained when I left if blank.

[mindslight]

I've seen forms that explicitly say to put in all nines if you "don't have one", so that's what I do everywhere that insists on asking but doesn't have a legitimate purpose (ie tax reporting). To any human it should be obvious that all nines indicates an exception.
