Frequently Asked Questions

What's the difference between a bank and credit union?

The main difference is ownership—banks are for-profit businesses owned by shareholders, while credit unions are not-for-profit and owned by their members. This means credit unions return earnings to members generally through lower loan rates, higher savings rates, and fewer fees.

Every credit union member has a savings account, called a "main share" account, which represents their ownership in the credit union. A minimum balance of $5 is required to keep the account open and maintain membership.

What information do I need to open an account?

To open an account you will need:

A government-issued, non-expired photo ID. If the address listed on the ID is not current, a document listing the current address is required. Generally, a utility or phone bill is acceptable.

For minor accounts, a social security card is required for the minor.
