Social Security numbers have not always been issued at birth. In the 70’s you didn’t get one until you were 16, or old enough to get your first job. That was when you got one. I got mine in 1974, when I was 16 and about to go to work. In the 70’s Obama would have done the same.
It was in the 80’s (as my children were born) that they were issued at birth.
Even then all 3 of my kids beginning 3 numbers matches the state ID.

All 6 members of my household match the formula.
Perhaps the formula was modified somewhere along the line.
