Tinker Federal Credit Union (TFCU) is the largest credit union in Oklahoma with over 430,000 members and more than $5.5 billion in assets. For over 70 years, we have been helping our members achieve their goals and realize their dreams. As a not-for-profit, member-owned financial cooperative, TFCU returns profits to our members through financial education, higher dividends on deposits, lower interest rates on loans and low or no fees on services. Founded March 20, 1946, by a small group of Tinker Field civilian employees, the financial institution now known as Tinker Federal Credit Union grew from a single branch at Tinker Field (now Tinker Air Force Base) to a network of branches across the state. We now offer 30 full-service branches and two Express Branches throughout Oklahoma City and as far reaching as Tulsa, Ada and Enid.Something looks off?
