About Allegiance Credit Union

As a local credit union that's been serving Oklahomans since 1963, Allegiance understands the needs of our community. Formally Federal Employees Credit Union (FECU), it was originally located in the basement of the Federal Courthouse and then moved into the Alfred P. Murrah Federal Building. In 1995, over half the staff was lost in the Oklahoma City Bombing. That day we learned the tough lessons of loss and adversity. Over time, we also learned about hope and renewal. The credit union was rebuilt on stronger bonds, stronger unity, and stronger ideals. In February 2002, FECU became a community charter, allowing membership from the six counties surrounding Oklahoma City, and led to the name change of Allegiance Credit Union (ACU) in May 2003. After converting to a federal charter in December 2021, the legal name changed to Allegiance Federal Credit Union, while still doing business as Allegiance Credit Unio
