Considering one of their questions was where OP was from, that's a strong possibility. If you know someone's birth city, that gives the first three digits.

Depending on what year they were born. They made it random in 2011. But since OP was drinking I hope she was born prior to that.

And to further reduce the search space, while SSNs don't have a checksum they do have "strong formatting" which means certain combinations of numbers are invalid. If you're down to just 2 digits (100 guesses) and apply those rules, you've pretty much got the number.

Not sure that’s true. My brother and I have the same first three but we’re born in different states.

FWIW I think it's where you were when you applied for the SSN. Because I ended up with the DC SSN because that's where I was when I turned 12 or 13, but I was born somewhere else in the US.

So maybe you and your brother were living in the same place when your SSNs were applied for?
