Credit cards do not have routing numbers
A routing number is a nine-digit code that identifies the bank or credit union where you hold a checking or savings account. Credit cards are not bank accounts, so they do not have routing numbers. If someone asks for your routing number in connection with a credit card payment or transfer, they are asking for the wrong piece of information.
The confusion often happens because both checking accounts and credit cards are issued by banks, and both involve money moving between institutions. But the systems that move that money work differently. A routing number tells the banking system where to send money for a deposit or withdrawal. A credit card has no account to deposit into or withdraw from — it is a line of credit, not a place where your money sits.
If you are trying to pay a credit card bill or set up an automatic payment, you will need your bank account's routing number (if you are paying from a checking or savings account), not your credit card's routing number, because no such number exists.
Key Takeaways
- Routing numbers belong to bank accounts (checking or savings), not to credit cards.
- If you are paying a credit card bill by bank transfer or automatic payment, you need your checking or savings account's routing number, not your card's number.
- Credit cards have a card number, expiration date, and CVV security code, but not a routing number.
- If a company asks for your credit card's routing number, they are either confused or asking the wrong question — clarify what account or payment method they actually need.
What numbers a credit card actually has
A credit card carries several identifying numbers, but none of them is a routing number. The card number (usually 16 digits for Visa or Mastercard) identifies the specific card and the account it is linked to. The expiration date tells merchants when the card stops being valid. The CVV or security code (three or four digits on the back) is used to verify you are the cardholder when you are not physically present with the card.
Your credit card statement also shows an account number, which is sometimes the same as the card number and sometimes different depending on the issuer. This account number is what the credit card company uses to track your balance and payments. It is not the same as a routing number, and it does not tell the banking system where to send money.
If you need to set up an automatic payment to your credit card from your bank account, you will enter your bank account number and your bank's routing number — not anything from the credit card itself.
When you need a routing number for credit card payments
You need a routing number when you are paying your credit card bill by transferring money from your checking or savings account. The routing number tells your bank where to send the payment. You will also need your own bank account number. Together, these two pieces of information let your bank route the payment to the correct destination.
You can find your routing number on the bottom left of your checks, or by calling your bank or logging into your online banking portal. Most banks also publish their routing numbers on their websites. If you are setting up automatic payments through your credit card company's website, the system will usually ask for your bank account number and routing number, not anything from your credit card.
If you are paying your credit card bill by credit card (using a different card, or a payment service), you would not need a routing number at all — you would just enter the card details of the card you are paying with.
Why the confusion happens
The mix-up occurs because banks issue both checking accounts and credit cards, and both involve the word "account." But they are different products with different underlying systems. A checking account is a deposit account where your money actually sits. A credit card is a borrowing product where the bank lends you money up to a limit, and you pay it back.
Routing numbers exist to move money between deposit accounts at different banks. Credit cards do not participate in that system in the same way. When you swipe a credit card, the transaction goes through a payment network (Visa, Mastercard, American Express) that works separately from the routing number system. When you pay your credit card bill, the money moves from your deposit account (which has a routing number) to the credit card company's account, but your credit card itself does not have a routing number.
What to do if someone asks for your credit card's routing number
If a company or person asks for your credit card's routing number, stop and ask what they actually need. They may be confused about what they are asking for, or they may be asking the wrong question. A legitimate business should be able to explain why they need a routing number and what they will do with it.
If they are trying to set up an automatic payment from your bank account to pay a credit card bill, they need your bank account number and your bank's routing number — not your credit card information. If they are trying to charge your credit card directly, they need your card number, expiration date, and CVV, not a routing number.
Be cautious if someone insists on a routing number in connection with a credit card when it does not make sense. Scammers sometimes ask for information they do not actually need in order to confuse victims or to gather data for identity theft. When in doubt, contact your credit card company directly using the number on the back of your card to confirm what information is actually required.
Frequently Asked Questions
Can I use my credit card number as a routing number?
No. A credit card number and a routing number serve completely different purposes in different banking systems. Using one in place of the other will not work and will likely cause a payment to fail or be rejected.
Do debit cards have routing numbers?
Debit cards are linked to a checking or savings account, so the account has a routing number, but the debit card itself does not. If you need to set up an automatic payment using a debit card, you would provide your bank account number and routing number, not the debit card number.
What if I need to send money to someone using their credit card?
You cannot send money directly to a credit card using a routing number. You would need to use a payment app (Venmo, PayPal, Cash App) or ask the person for their bank account details if they want a direct bank transfer. Credit cards are for borrowing, not for receiving deposits.
Is my credit card account number the same as a routing number?
No. Your credit card account number identifies your credit card account with the issuer. A routing number identifies the bank or credit union where a deposit account is held. They are two different numbers used for two different purposes.
