A: Since 1935, we have assigned more than 465 million Social Security numbers and each year we assign about 5.5 million new numbers. With approximately 1 billion combinations of the nine-digit Social Security number, the current system will provide us with enough new numbers for several generations into the future.

Q: How do I change my citizenship status on my Social Security record?
A: To change the citizenship shown on our records you need to:
Complete an Application For A Social Security Card (Form SS-5), available at www.socialsecurity.gov/ssnumber/ss5.htm, and show us documents proving your age, identity and new or revised citizenship status. (We only accept certain documents as proof of citizenship. These include your U.S. passport, a Certificate of Naturalization or a Certificate of Citizenship. If you are not a U.S. citizen, Social Security will ask to see your current immigration documents.)
Take (or mail) your completed application and documents to your local Social Security office. All documents must be either originals or copies certified by the issuing agency. We cannot accept photocopies or notarized copies of documents.
