Important information about procedures for opening a new account

To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account. That's why, when you open an account, we will ask for your name, address, date of birth, and other information that will allow us to identify you. We may also ask to see or request a copy of your driver's license or other identifying documents.
