Alliant Credit Union Headquarters

The health, safety and wellness of our members and our employees is incredibly important to Alliant. Like many companies across the country, Alliant is taking precautions to help safeguard against the risk of a coronavirus outbreak. While we have had no coronavirus cases, our two Chicago-based branches will be closed until further notice. You can continue using online and mobile banking, our 80,000+ in-network ATMs or contact the Member Care Center at 800-328-1935.
