A Bank OZK routing number is a nine-digit code that identifies a specific financial institution and branch for electronic fund transfers. For instance, the Bank OZK routing number for the main branch in Little Rock, Arkansas, is 082900530.
Routing numbers ensure that funds are sent to the correct bank and account. They are essential for various financial transactions, including direct deposits, wire transfers, and ACH payments. Historically, the American Bankers Association (ABA) introduced routing numbers in the 1910s to streamline the national check clearing system.
