In Indianapolis, you can go downtown to the Indiana Department of Health and request a copy of your birth certificate. You may want to call them in advance for costs and availability, location, etc. Then, you can go to your local social security administration office, such as the one at 575 N. Pennsylvania downtown for your social security card (free).
