That’s not true.Social Security numbers were only issued when you applied for it yourself or your parents applied.
I know because I didn’t have one untill I turned seventeen and needed it to get a job.That was in the late 1960’s.
I never APPLIED for ssn...i just walked in and took the 1st one on the pad and my friend the next one....i was 14 this was in 1966...ks..... No one ever said I had to fill out any thing..we went to office @ lunch time from school....
Been using it ever since... maybe different procedures,
different parts of country?
