When you call, the automated voice response system will ask you to provide your social security number (SSN) and your personal identification number (PIN). If you do not have a PIN or do not remember your PIN, you will have to request a new one. You can request a new PIN using the automated voice response system or online at I Need a PIN. You may also be asked to provide your Participant Identification Number (ID). You can find that number on many of the letters or notices we send to you.
