If you legally change your name because of marriage, divorce, court order or need to correct your name for other reasons, you must tell Social Security so you can get a replacement SSN card with your correct legal name. See Defining the legal Name for an SSN.
To get a name corrected SSN card, in most cases, you will need to complete an Application for a Social Security Card and present the required documents. You will need evidence of your identity, your new legal name, and name change event. Sometimes you also may need to prove your current U.S. citizenship or lawful noncitizen status.
For a list of documents you need, go to the Learn What Documents You Need page and select “Corrected” under the “Type of Card” heading.
