I think she was born in 1980, but literally everyone else I knew had a SSN their whole life. I think you're an outlier, but I'm just speaking from my own limited experience. Have you met other people your age who didn't have SSN as kids? When my son was born we just filled out a form at the hospital. I'm pretty sure they filed it for us, although I can't remember for sure, since it has been a couple of decades now.
