What is an ABA Number and Why It Matters in Banking

Definition & Meaning

An ABA number, or ABA transit number, is a unique nine-digit identifier assigned to banks and savings associations by the American Bankers Association (ABA). This number is typically found in the lower left-hand corner of U.S. checks. The ABA number consists of two parts: the first part indicates the geographical location of the bank, while the second part identifies the specific bank itself. To receive an ABA number, a financial institution must be authorized to hold an account at a Federal Reserve Bank. This number plays a crucial role in the sorting and clearing of checks and helps identify the bank processing the payment.
