A “Bank of America ABA number” is a nine-digit routing number assigned to Bank of America. It is used to identify the financial institution when processing electronic payments. For instance, if you are setting up direct deposit with your employer, they will ask for the ABA number and your account details.
ABA numbers ensure the secure and efficient transfer of funds between banks. They streamline financial transactions, facilitating operations such as direct deposits, wire transfers, and bill payments. Historically, the American Bankers Association (ABA) established these numbers in 1910 to standardize the banking system.
