Benefits Questions or Changes

If you have questions or need to make changes to your benefits, call 877-353-5100.

As a first-time caller to this new center, you will be prompted to set up a Personal Identification Number (PIN) with a minimum of six-digits for security purposes. You will also need the last four digits of your social security number, date of birth, and zip code.

Once you have a PIN, remember this number as you will be required to enter it each time you call.


The P&C Hub is a new HR resource center with access to all benefits information. Retirees can request help via online appointment scheduling, service requests, phone call or web chat. First time users can create a PIN by phone or within the P&C Hub.
