What is… a ROUTING NUMBER?

A Routing Number (or transit routing number) is a nine-digit number used to identify a United States bank or financial institution, and it is assigned by the ABA, or the American Bankers Association. It is used primarily for clearing funds for electronic transfers or for processing checks. Routing Numbers are also used for financial transactions in online banking and financial clearinghouses.

Federally-chartered and state-chartered banks and institutions that qualify for an account at a Federal Reserve Bank are issued Routing Numbers by the American Bankers Association (ABA). Since the ABA assigns bank routing numbers, there’s no risk of errors or duplication between banks.

Can banks have more than one Routing Number?

Yes! In fact, most banks and financial institutions have more than one Routing Number, for example, one for wire transfers and others for direct deposit or ACH transactions. 

In most cases, the Routing Number for your checking account is based on the state where your account was opened.

Do debit cards or credit cards use Routing Numbers?

No. Routing Numbers are only used for transfers between bank accounts. Your debit card is associated with a bank account but you do not need a Routing Number for debit card transactions.

Credit cards do not need Routing Numbers since they are not linked to a bank account. That said, there are situations where you might need your Routing Number handy, for example, when you go to pay your credit card online you may need your Routing Number to set up a link between your credit card and checking account.

What about international transactions?

Generally, SWIFT or IBAN numbers are used for international (non-U.S.) transactions.
