RM 10205.405 Exception to SSN Card Limits for Name Change
When a number holder (NH) reaches his or her yearly or lifetime SSN card limits, an SSN replacement card may still be issued if the NH reports a legal name change.
A legal name change is a change to the first name or surname. A change to the middle name or middle initial is not considered a legal name change. However, if the NH presents a court order changing only his or her middle name, grant an exception and process the change.
