If you legally change your name because of marriage, divorce, court order or any other reason, you need to tell Social Security so that you can get a corrected card. If you are working, also tell your employer. If you do not tell them when your name changes, it may:
If you need to change your name on your Social Security card, you must show them a recently issued document as proof of your legal name change. Documents Social Security may accept to prove a legal name change include:
If the document you provide as evidence of a legal name change does not give them enough information to identify you in our records or if you legally changed your name more than two years ago, you must provide Social Security with additional documentation.
Marriage, divorce or annulment: In addition to showing them a legal document proving your marriage, divorce or annulment, you must provide an identity document. That document must show your old name, as well as other identifying information or a recent photograph. (We can accept an expired document as evidence of your old name.)
Adoption, naturalization or other name change: In addition to showing them a legal document citing your new name, such as a court order, adoption decree or Certificate of Naturalization, you must provide them with two identity documents, including:
Both of these documents must show identifying information or a recent photograph.
Citizenship:Also, if you are a U.S. citizen born outside the United States and our records do not show you are a citizen, you will need to provide proof of your U.S. citizenship. If you are not a U.S. citizen, Social Security will ask to see your current immigration documents.
Your new card will have the same number as your previous card, but will show your new name.
