Change of Social Security Number

If you change your Social Security number, please follow these steps:

  • Complete a Change of Social Security Number form available at the Registrar's Office
  • Present the new, original Social Security card and a picture ID; both will be photocopied

Once the application has been presented at the Office of the Registrar, please allow a minimum of 48 hours for the change to take effect.

If you are employed by Northwestern University, you must also make the official change of Social Security number at the Office of Human Resources.
