Do Credit Cards Have Routing Numbers?

You might be wondering if your credit card has a routing number. The short answer is no, it doesn’t.

Credit cards have an account number that’s displayed on the card, an expiration date, and a Card Verification Value (CVV) code. Debit cards, on the other hand, are attached to a bank account, which does have a routing number. In this article, we’ll explain what a routing number is, why it’s used, and where you can find it.        

A routing number is a nine-digit unique identifier used by banks and other financial institutions in the United States. It ensures that fund transfers between financial institutions are routed correctly. They are not used outside of the United States. For international money transfers, international bank account numbers (IBANs) or Society for Worldwide Interbank Financial Telecommunication (SWIFT) codes may be used.¹

The system was invented in 1910 by the American Bankers Association (ABA) to help make it easier to process paper checks between banks.² Initially, it was a system to help the ABA process checks, which is why the identifiers are also called ABA routing numbers or ABA numbers. These monikers all refer to the same nine-digit code.

Banks are given routing numbers based on the states in which they operate. So banks in different states will have different routing numbers.

If you have a checking account, your bank’s routing number is displayed in the bottom left-hand corner of your checks. The numbers following that nine-digit identifier are your account number. The combination of those two elements accurately identifies the financial institution and the individual account that is either sending or receiving money.

A routing number identifies a specific financial institution. It’s an essential identifier when transferring money from one bank account to another. That’s not what happens when you use your credit card. With a credit card transaction, you’re borrowing funds against your credit limit, and this transaction will be processed differently. The credit card number helps to track your transactions and ensure they end up on your monthly bill and helps the card processors identify the financial institution that will settle the payment.

Credit cards don’t have routing numbers. The unique identifier for a credit card is a number that’s typically fifteen to twenty-one digits long displayed on the front or back of the card. The first number in the sequence identifies the credit card provider. For instance, American Express credit card numbers (CCN) are fifteen digits starting with a 34 or 37.

Another identifier on your credit card is the expiration date. Most merchants will ask for this when you make a purchase over the phone and check it when you buy something in person. An expired credit card will typically register as “invalid” if you try to swipe it or make an online purchase with it. Your credit card provider should notify you when your card is set to expire.

The third identifier on a credit card is the card verification value (CVV) code. On most cards, it’s a three-digit security code printed on the back of the card. American Express uses a four-digit code printed on the front of the card. This feature, combined with chip technology used to encrypt user data, helps to ensure credit card transactions are safe and secure.
