This directory covers the 3,393 FDIC-insured institutions reporting at least one branch in the 1,523 counties within a Combined or Metropolitan Statistical Area, per the FDIC Summary of Deposits, June 30, 2026. It is not a census of every U.S. institution. Total assets are the figure each institution carries in that same SOD; deposits shown are total SOD deposits across every county where the institution reports a branch. See the methodology for how each figure is built, or the disclaimer for how this data should, and should not, be read.
Institutions are named on this page solely to describe publicly reported FDIC data. A listing does not imply any affiliation between any institution and The Executive Recruiter Group, or endorsement by either.
