Cornerstone Credit Union is a not-for-profit financial cooperative. When you join a credit union, you own a piece of it and have a say in how it’s run. Credit unions exist to serve their members, not to make a profit. That means their number one concern is not money, but members. That translates into great rates, low fees and exceptional service.

Today, we serve more than 13,600 members and are open for membership to anyone who lives or works in the following northwest Illinois and southern Wisconsin counties. Illinois: Boone, Bureau, Carroll, JoDaviess, Ogle, Lee, Stephenson, Whiteside, and Winnebago Counties. Wisconsin: Green and Rock Counties. Family members of current CCU members also can join. We are the only local credit union in South Beloit and look forward to serving you.
