A Lifetime Benefit
Once a member, always a member...
Once your accounts are opened, you and your family may remain active members for life, no matter where you later live or work — even if you leave the employer that originally qualified you for membership.
Important Information on Opening 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.
What this means for you: 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 your driver's license or other identifying documents.
Why Can't Anyone Join?
It's not our choice — it's the law! Credit unions are allowed to serve only their members. As a state-chartered credit union, GCS receives its charter authorization to operate from the Department of Financial Institutions in the State of Illinois. That charter spells out in detail just who's eligible for membership. While we are state chartered, our deposits are federally insured by the National Credit Union Administration.
