A CUSIP number identifies most securities, including: stocks of all registered U.S. and Canadian companies, and U.S. government and municipal bonds.
They aren't tied to a social insurance number.
So what you are trying to do isn't possible.
A cusip number is attached to a security and there are securities--either bonds, or mutual funds, I am not sure which, yet---that are linked to our birth registration number and, or our S.I.N. That is, we are securitized at birth and traded in the international bond market. This is fact, not fantasy. There are people who have located this CUSIP number. It looks as if I shall have to do the deep research. Cordially, Charles
