What are the most important forms of ID to have?
NATURALIZED U.S. CITIZEN?
If you were born outside the U.S. and then became a citizen through the naturalization process, instead of a birth certificate, you need your naturalization certificate. For details, go to PG. 37.
As you rebuild your life in the community, there are 3 KEY DOCUMENTS for you to have: (1) your birth certificate; (2) your Social Security card (or number); and (3) a state ID or driver license (you don't need both, just one).
Once you have your birth certificate and Social Security number (SSN), you will be able to get a California state ID card or a driver license, the most commonly used forms of ID for everyday purposes. Once in a while, you will need to show a copy of your Social Security card for certain services, just knowing your Social Security number (SSN) is enough (without presenting the actual card).
