About Alliant Credit Union - Corporate Headquarters
Alliant Credit Union is the largest credit union in Illinois and one of the largest in the U.S., with over 85 years of history and 900,000+ members nationwide. As a 100% digital and not-for-profit institution, Alliant offers high savings and checking rates, low loan rates, rich credit card rewards, and fewer fees to reward its members. Customers praise Alliant's excellent customer service, with consultants who are able to swiftly and patiently assist with issues. The credit union's user experience is also highly regarded, and members appreciate the company's mission and the ability to feel good about where they keep their money. Alliant's 2.5% cash back credit card is described as the best cash back rate in the country, and the credit union's car loan process is praised as hassle-free. While Alliant no longer maintains a walk-in branch in the Chicago area, it refunds ATM fees and does not nickel-and-dime customers with various fees. The only potential downsides mentioned are long wait times on the phone and the challenge of finding ATMs that accept cash deposits. However, these inconveniences are often outweighed by Alliant's exceptional online service, seamless mobile app, and the sense that the credit union always has its members' backs.
