I was born in Casablanca, Morocco in 1944.

My parents where both US citizens, so I am a US citizen with US passport.
Moved to the States and went to High School in Yonkers New York from 1959 to 1962.

Moved to Switzerland in 1963, I am now retired and live and have worked in Switzerland.

I paid all my income taxes and social security to the Swiss IRS and Swiss AVS.

I have to fill out a taxe declaration to the US IRS (even though I never earned a cent in the US !), but need my SSN to do so.

How can I find my number? I'm not even sure I had one when I was in High School. (I never had a job during those years) I do have a Selective Service card for the Draft.

Thanks for your help !

The only way I know of is to apply for a number now, which you can do online at socialsecurity.gov. I doubt that you have one. In the 60s it wasn't nearly as common as it is now, unless you had a job or your own bank account as a teen.

You need to contact the Social Security Administration to determine if you have a SSN. The Selective Service Number MAY also be your SSN; they converted sometime in the 1960s.
