The documents you need will depend upon your citizenship.
Are you an established U.S. citizen?
No, I am not.
In this case, you will need proof of U.S. citizenship.
What do I need to prove my identity to Social Security?
You will need a U.S. driver's license or a state issued id card.
I just got married and have changed my last name. How do I change it on my new Social Security card?
You will need a document that shows proof of a legal name change such as a marriage document.
What do I do if I don't have a driver's license or an id card?
You can use other documents such as an employee id card. However, they must not be expired and must show your name and date of birth or age. We also prefer that it contains a recent photograph of yourself.
Will my new Social Security card have the same number as my previous card?
