County Bank is an Iowa chartered bank first organized in 1884 in Sigourney, Iowa. Currently County Bank’s main office is on the southeast corner of the Square in Sigourney with locations in Deep River, Gibson, Montezuma and Williamsburg. 

County Bank has a strong commitment to the communities we serve. County Bank, our Board members, managers and employees have a long-standing tradition of charitable giving and sponsorship of activities in our communities and will be found working side-by-side on many local projects.

In 2015 County Bank entered a new generation of banking with the introduction of "PAT", a Personal Automated Teller that combines the convenience of an ATM with the personal service of a County Bank Personal Banker. PAT will be introduced at 6 sites in coordination with County Bank’s Sigourney, Williamsburg and Montezuma locations. PAT joins County Bank’s package of 24/7/365 Electronic Banking Services including ATMs, Online Banking, Online Bill Pay (iPay), Mobile Banking with optional Remote Deposit and eStatements.
