Key Differences
The ABA Number is a unique code established by the American Bankers Association to identify individual banks in the United States. This number plays a crucial role in ensuring that funds are sent and received by the correct institutions. The Routing Number, on the other hand, is a nine-digit number used by banks to identify themselves.
The Routing Number is essentially another name for the ABA Number. While the term "ABA Number" emphasizes its establishment by the American Bankers Association, the term "Routing Number" focuses on its primary function - to route payments and transfers correctly.
When initiating a wire transfer or setting up an electronic payment, the ABA Number, or Routing Number, is often required. Both numbers are crucial in ensuring that the funds reach the intended bank account. Thus, it's imperative to use the correct ABA Number or Routing Number.
Both ABA Number and Routing Number can be found on the bottom of a check. While the terms can be used interchangeably, their dual nomenclature stems from their association with the American Bankers Association and their function in the financial world.
