Recently, I experienced fraud on my checking account. Since my house payments were automatically made each month on that account, I needed to contact PNC Mortgage to change the account numbers. I was dismayed to discover they insist on using my social security number for identification when I phone in. I know they need it for tax purposes, but a phone call about my mortgage is not a tax issue. They refuse to change their policy. BE VERY CAREFUL!!!

They probably need it to be sure you are the person that is on the mortgage, how else can they confirm your identity over the phone? If they don't positively confirm the identity, anyone could call in and change your payment setup.
