Credit cards are a ubiquitous part of modern life, allowing individuals to make purchases with ease and convenience.
While many people are familiar with their credit card number, some may wonder if credit cards have routing numbers like bank accounts do. Routing numbers are a crucial element of the banking system, but do they apply to credit cards as well?
In this article, we will explore do credit cards have routing numbers and delve into other important details about credit card identification.
What Are Routing Numbers?
Routing numbers are nine-digit numbers used to identify financial institutions in the United States. These numbers are also referred to as ABA routing numbers or routing transit numbers.
They were introduced in 1910 by the American Bankers Association (ABA) to simplify the processing of paper checks between banks. Only state or federally chartered financial institutions can obtain a routing number.
A routing number is unique to a specific financial institution and is used for a variety of financial transactions, including ordering checks, processing wire transfers, and setting up direct deposits.
The first four digits of a routing number indicate the Federal Reserve Bank district where the institution is located. The next four digits identify the specific bank or credit union, while the last digit is used to verify the validity of the routing number.

You can typically find your routing number on the bottom of your check, in your online banking account, or by contacting your financial institution. The routing number is specific to your bank or credit union, so it’s important to use the correct number for your transactions.
Do Credit Cards Have Routing Numbers?
Credit cards do not have routing numbers, unlike bank deposit accounts, such as checking or savings accounts, that require routing numbers for transactions.
The 15- or 16-digit account numbers on credit cards identify the account holder’s credit limit and are used for transactions rather than routing numbers.
The credit card issuer adds charges to the account, so the account number is required for transactions, along with the card verification value (CVV) and ZIP code, depending on the transaction.
While some banks issue both deposit accounts and credit cards, credit cards do not require routing numbers because they are not used to transfer money between banks.
Instead, a portion of the credit card number identifies the issuing company, following the first digit that identifies the card network, such as Visa, Mastercard, or American Express. The issuer identification number identifies the financial institution that issued the card.
The credit card account number may be printed on the front or back of the card or found on the monthly statement or online account. Some cards may not display the full account number, but you can usually access it if needed.
Overall, credit cards do not need routing numbers, as they are a loan facility and do not rely on routing in any transaction. However, you may need to provide a routing number when setting up a credit card as a payment method to transfer funds from a deposit account to pay the credit card.
Why don’t credit cards use routing numbers?
Credit cards do not have routing numbers since they are not used for wire transfers or direct deposits, which require a routing number to complete transactions between two bank accounts.
Instead, credit cards use an account number to link card transactions to an account and keep a running tab of charges, which can be paid off at a later date.
When using a credit card, the customer is essentially borrowing money from the card issuer, and the payment settlement mechanism is different from that of wire transfers and direct deposits.
The bank pays the merchant in full, and the customer only needs to pay the bank when the billing cycle comes around. Therefore, routing numbers are not necessary for credit card transactions, as they do not rely on routing numbers to process transactions like wire transfers and direct deposits.
Routing Number vs. Account Number
The routing number and account number serve distinct purposes. The routing number identifies the financial institution where your account is held, while the account number uniquely identifies your account within that institution. The routing number is a nine-digit code used to route money to and from your bank, while the account number is used to identify your specific account when conducting transactions.
It’s important to note that if you have multiple accounts with the same bank, your routing number will likely be the same for all accounts, but each account will have a unique account number.
Depending on the banking activity, you may need to provide the routing and account numbers or just one of them. For example, when setting up direct deposit for your paycheck, you only need to provide your routing number. However, if you are sending a check or making a wire transfer, you must provide both the routing and account numbers.
Remember that the account number is only used by you and authorized users of your credit card, while the routing number is used by multiple accounts at the same bank to facilitate transactions.
Credit card number vs. routing number
The credit card number and the routing number serve different purposes. The credit card number is a string of digits unique to your credit card and is used to identify your account and the issuer.
The credit card number can range from 16 to 21 digits and is usually printed on the front or back of your card. On the other hand, the routing number is a 9-digit code that identifies a US financial institution and is used to route money transfers and other payments between banks.
While multiple accounts from the same bank may share the same routing number, each credit card has its own unique number.
A routing number is essential for sending and receiving funds between financial institutions but is not necessary for credit card transactions.
Credit card transactions involve different payment processing protocols and channels, which don’t require a routing number. Instead, your credit card number allows you to make purchases online and identifies your account and issuer.
Do Credit Cards Have Account Numbers?

Your credit card has a unique 15- or 16-digit account number that identifies your card account. This number is typically printed on the front of the card, but some card designs may have it on the back or not print it at all, like the Apple Card. You can also find it on your monthly statement or online account, with the option to view the entire number.
The account number contains identifying features that provide information about your card, such as the credit card issuer and the financial institution that issued the card. For example, American Express account numbers always start with 37 or 34, while Mastercard account numbers start with 5. The remaining digits are unique to your specific account.
This unique string of numbers is used to tie your credit card transactions to your credit card statement. Knowing your credit card account number is essential for making purchases online or over the phone and for accessing your account information.
What accounts use routing numbers?
Routing numbers are primarily used in connection with deposit accounts such as checking and savings. These types of transactions often involve transferring, withdrawing, or depositing funds between financial institutions. Routing numbers play a critical role in ensuring that these transactions are processed correctly.
If you hold both a checking and savings account with the same bank, the routing number is likely to be the same for both accounts. This is because the routing number identifies the financial institution, not a specific account.
In the case of large banks, routing numbers are associated with various types of accounts. For instance, you can expect to have a routing number linked to your personal checking and savings accounts. Additionally, business owners who have business checking and savings accounts will also have routing numbers associated with these accounts.
Why Do Banks Have Routing Numbers?
The purpose of a routing number is to facilitate the identification of financial institutions during financial transactions. In addition, when a transaction is initiated, a clearinghouse uses the routing number to ensure that the financial transaction is processed correctly.
To obtain a routing number, a financial institution must be eligible for a master account by a Federal Reserve Bank and prove that it meets the requirements of a federal or state-charted institution.
The routing number system was established in 1910 to streamline and improve the accuracy of financial transactions. The use of a 9-digit code allows for easy identification of different financial institutions during transactions.
To complete a modern banking transaction, the routing and account numbers are necessary. Therefore, these two pieces of information are vital for ensuring the efficient operation of the banking transaction system.
How to find your routing number
The routing number for your checking or savings account can typically be found in a few different places.
Firstly, when you open a new account, the paperwork you receive will usually include your routing and account numbers.
Secondly, your bank’s routing number can be found on the bottom left corner of your physical checks as the first 9 digits.
Thirdly, many financial institutions now offer secure online portals and mobile banking apps where you can easily locate your routing number by accessing your account details.
However, some larger financial institutions may have multiple routing numbers for different areas of operation or transaction types, which can make finding your routing number a bit more challenging.
Suppose you can’t locate your routing number through any of these methods. In that case, you can try looking at the bottom of your financial institution’s website or contact their customer service team for assistance.
How to Protect Your Credit Card Number: Tips to Keep Your Information Safe
Credit cards may not have routing numbers, but thieves are still after your account number and CVV. Keep your credit card information safe with these tips:
- Don’t take photos or videos of your credit card. Your credit card number can be easily stolen if thieves see it.
- Avoid exposing your credit card in public longer than necessary. Use tap-to-pay options on your phone or watch, if available.
- Don’t write down your credit card number, as thieves can find it, even in your trash.
- Sign up for electronic statements to prevent thieves from accessing your mailbox.
- Use virtual account numbers to protect your real credit card number when shopping online.
- Use digital wallets for safer payments, as your card data is encrypted and tokenized.
- Watch out for scams that target credit card numbers, and don’t give out personal information to anyone who asks for it.
- Use a credit card with fraud protection, so you’re not liable for unauthorized charges.
Final Thoughts
To avoid theft and fraud, it’s important to protect your credit card account number, which is used to identify your account, unlike routing numbers that are used to identify banks.
While routing numbers are used for services like direct deposit, automatic payments, and transfers, credit card transactions rely on the 16-digit credit card number, which includes specific digits that identify the issuing company.
You can typically find your credit card account number on the card itself, but keeping it safe and avoiding sharing it unnecessarily is important.
