Enter your personal information in the application. Type your Social Security number, name, date of birth, mailing address and email address in the appropriate forms.
Select a challenge question and then provide an answer for the question you selected. Make sure you select something that you can remember since you will need the answer if you forget your PIN.

Check the box next to "I agree not to share my PIN" and click "Submit My Application." After your PIN application is approved, you can use your PIN to sign your FAFSA application.
