Credit cards do not have routing numbers
A routing number is a nine-digit code that identifies the bank or credit union where your checking or savings account lives. Credit cards are not bank accounts — they are lines of credit issued by a card company. Because credit cards do not hold money the way a bank account does, they do not need routing numbers.
If you are looking for a routing number to set up a payment or transfer, you are probably thinking of your checking account, not your credit card. The two are separate financial products, even when the same bank issues both.
Key Takeaways
- Routing numbers belong to bank accounts (checking and savings), not credit cards.
- Credit cards use a card number, expiration date, and CVV code instead — never a routing number.
- If a form asks for a routing number, it is asking about a bank account, not your credit card.
- You can pay a credit card bill from a checking account using that account's routing number, but the credit card itself has no routing number.
What a routing number actually identifies
A routing number tells the banking system which financial institution holds your account. When you set up direct deposit, make an ACH transfer, or pay a bill from your checking account, the routing number directs the money to the right place. It is part of the infrastructure that moves money between bank accounts.
Credit cards work differently. When you use a credit card, you are borrowing money from the card issuer. The card issuer then bills you later. There is no account sitting somewhere holding your credit card balance the way a checking account holds your paycheck. That is why a routing number does not explore.
What credit cards use instead of routing numbers
Every credit card has a card number — usually 16 digits printed on the front. This number identifies your specific credit card account with the card issuer. It is not the same as a routing number and serves a different purpose.
Credit cards also have an expiration date and a CVV code (the three or four-digit security number on the back). Together, these three pieces of information are what merchants and payment processors use to process a transaction. You will never be asked for a routing number when you use a credit card.
When you might confuse the two
The confusion usually happens when you are paying your credit card bill. To pay your credit card, you often use your checking account — and that checking account does have a routing number. You might be setting up an automatic payment from your bank to your credit card company, or you might be making a one-time transfer.
In that situation, you are using your checking account's routing number to send money to the credit card company. But the credit card itself still has no routing number. The routing number identifies where your money is coming from, not the credit card you are paying off.
How to find your routing number if you need it
If a form or payment system asks for a routing number, it is asking about a bank account, not a credit card. You can find your routing number on the bottom left of your checks, or by logging into your bank's website or app. Most banks also list it on their website under account information or customer service.
If you are trying to pay a credit card bill and a form is asking for a routing number, you are on the right track — you are using your checking account to make the payment. Just make sure you are entering your checking account's routing number, not anything from the credit card itself.
Credit cards and bank accounts are separate products
Even when one bank issues both your checking account and your credit card, they are two different products with different identifiers. Your checking account has a routing number and an account number. Your credit card has a card number, expiration date, and CVV. Neither one replaces the other.
If you are managing both accounts with the same bank, you can usually see them both in your online banking portal. But they are tracked separately, and each one uses its own system of identification.
Frequently Asked Questions
Can I use my credit card number as a routing number?
No. A credit card number and a routing number are completely different. A routing number identifies a bank or credit union. A credit card number identifies your credit card account with the card issuer. Using one in place of the other will cause the transaction to fail.
What if I need to pay my credit card bill online?
You do not need a routing number to pay your credit card bill online. Log into your credit card company's website or app and look for the payment section. You can usually pay from a checking account, savings account, or debit card without entering a routing number — the payment system handles the routing behind the scenes.
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 have a routing number. If you need to set up a transfer using a debit card, you would use the routing number of the bank account the card is connected to.
Why do credit cards not have routing numbers?
Credit cards are not bank accounts. They are lines of credit. Routing numbers are part of the banking system that moves money between accounts. Since a credit card does not hold money or receive deposits, it does not need a routing number.
What information do I need to give someone to pay my credit card bill?
If someone is paying your credit card bill for you, they need your credit card number, expiration date, and CVV — the same information you would use to make a purchase. They do not need a routing number. If they are sending money from their own bank account to your credit card company, they would use their own bank account's routing number, not yours.
