In March 1972, we began assigning SSNs and issuing SSN cards centrally from Baltimore,
MD. The SSN and name, for both original and replacement cards, are printed on the
card and mailed from central locations to the number holder at the address furnished
on the application.
NOTE: A very small number of SSN cards have the SSN and name typed manually in central
office (CO). For example, to replace cards mutilated in the automated printing process
for which name, address, and SSN are still legible).
