FSNB, formerly known as Fort Sill National Bank, has a tradition of distinguished banking service to both the military and civilian communities. In 1942, the Fort Sill command asked the City National Bank of Lawton to establish a check-cashing facility on the Army post of Fort Sill, home of the U.S. Field Artillery School. Four years later, J. R. “Dolph” Montgomery had the vision to establish a full-service bank to meet the special banking needs of Fort Sill’s military personnel. Through hard work and determination, Mr. Montgomery founded Fort Sill National Bank on April 19, 1946, and forged a legacy as a leader in military banking and customer service.

Routing/Wiring Instructions

FSNB Bank customers will be required to have a routing number or routing transit number is a 9 digit number that identifies a financial institution in a transaction and the location where your bank account was opened.
