About the institution. First Bank is identified by FDIC certificate number 12229. The headquarters address shown (4387 N Illinois St, Swansea, Illinois) is the branch with the lowest internal unique number — typically the institution's main office. For multi-state institutions, this is its legal HQ, which may differ from the corporate brand's perceived home (e.g., several brands consolidate to a Delaware or Ohio charter).
