What is a routing number?

An ABA routing number is a 9-digit code issued by the American Bankers Association and used by the Federal Reserve to route ACH transfers, wire transfers, and paper checks. Each number is assigned to a single financial institution of record.

Why does one number show multiple banks?

The routing number itself is owned by one bank. Smaller banks, credit unions, and most fintechs do not have their own number — they process ACH and check traffic through a larger sponsor or correspondent bank, so their accounts appear under the sponsor's routing number. The owner is listed first above.
