Do TINs overlap with SSNs? Because businesses and non-citizen taxpayers have TINs instead of SSNs, but they’re used just the same.

This I don’t know. I remember reading that around 70%(?) of SSNs have been allocated, and there are enough left for a few decades. No idea whether corporation TINs come from that. I believe non-citizen taxpayers get similar SSNs to citizens. IDK if they pay into social security and collect benefits the same way.
