do you need it for something?
Go online on your computer to http://www.mysocialsecurity.gov and make yourself an account there. write down the username and password you will create for your account... keep that someplace you can refer back to when you re-visit.
On the site you can request tehm send you a new social security card if you need one.
You hopefully know your Social Security number because you will need it to sign in to mysocialsecurity.gov
Simple as that....
