The ABA Number and Routing Number are essentially the same, both identifying financial institutions in the U.S. for payment processing.
Key Differences
The ABA Number is a unique code used to identify banks and other financial institutions in the United States for payment processing, primarily in paper check transactions. The Routing Number serves a similar purpose, used to identify banks when processing electronic transfers and checks.

ABA Numbers were originally created by the American Bankers Association (ABA) to streamline paper check processing. Routing Numbers, often synonymous with ABA Numbers, are used in electronic transactions like direct deposits and bill payments, in addition to check processing.

Both ABA Numbers and Routing Numbers consist of nine digits. The first two digits in an ABA Number indicate the Federal Reserve district where the bank is located, a feature also mirrored in the Routing Number system.

The ABA Number is sometimes referred to as the check routing number, while the Routing Number may also be known as an ACH routing number, particularly when used for electronic transfers. However, both terms are often used interchangeably in the banking sector.

In summary, while the terms ABA Number and Routing Number originated from different banking processes (paper checks for ABA and electronic transfers for Routing), they are now used interchangeably in most banking contexts to identify financial institutions in the United States.
