An ABA number, also known as a financial institution’s routing number, is a nine-digit code that identifies banks, credit unions, and other financial service companies offering banking products in the U.S.

ABA, the organization that created the number, is an acronym for the American Banker’s Association.

The ABA number helps other banks transfer money to and from checking or savings accounts for transactions like direct deposit, bill payments, and transfers.

An ABA number is a safeguard that allows financial institutions that take deposited checks to verify the legitimacy of the originating bank that issued the check and held the funds.
