2. I don't even understand how a title transfer could happen without verifying ownership. Is the title system in the USA decentralized or that much different than elsewhere? i.e. Torrens-style
It wasn't easy to clear up, either. I'm fortunate that a close friend worked (at the time) for the SS administration, and was able to do basically all of the leg-work for me: I just had to sign a few forms he sent me. Someone not equally connected would have had a much harder time.
I'm also painfully aware that effectively every scrap of everyone's personal data has been repeatedly leaked online. I doubt that any amount of care has much to do with whether or not I'll be targeted at some point in the future.
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.
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.
