First Community Credit Union is located off Highway I-70 on Wentzville Parkway and situated inside of the Walmart store. This in-store banking concept is being used throughout the country to provide a convenient service since many families seem to both bank and shop during the same time frame. This type of branch still has all of the same services available as the free-standing version. If you live or work in St. Charles County, you qualify to become a member. Membership means that you own part of the credit union and are eligible to receive lower loan rates and higher savings account yields.
