Your credit card account number is the 15 or 16-digit number printed on the front of your card, usually below your name.
This number is unique to your card and is different from your card number itself — though they are often confused. The account number identifies your specific account with the card issuer (your bank or credit card company), while the card number is what you use to make purchases. You will see the account number on your physical card, in your online banking portal, and on your monthly statement.
You need your account number when you call your card issuer's customer service line, when you set up automatic payments, or when you are resolving a dispute. It is also the number you use to log into your account online or through the card issuer's mobile app. Keeping this number separate from your card number in your mind helps you understand which one to share in different situations.

Where to find your account number on your physical card
Look at the front of your credit card. Below your name, you will see a series of numbers. The first four digits are usually printed separately or in a different color. The remaining 11 or 12 digits make up your account number. This is the number you should memorize or write down in a safe place if you need to reference it without the card in front of you.
Not all card issuers print the account number in the same location or format. Some cards print it below the main card number, while others print it in the bottom right corner. If you cannot locate it on your card, the easiest way to find it is to log into your online account or call the customer service number on the back of your card.
How to find your account number online
Log into your card issuer's website or mobile app using your username and password. Once you are logged in, your account number will appear on your account dashboard or home page. It is usually displayed prominently near your available credit, current balance, or recent transactions.
If you cannot find it on the main page, look for a section labeled "Account Information," "Card Details," or "Account Settings." Some issuers also display your account number on the page where you can view your statement or payment history. If you still cannot locate it, use the search function within the app or website to search for "account number."
Finding your account number on your monthly statement
Your monthly statement lists your account number near the top, usually in the upper left or right corner. It appears alongside your statement date, billing period, and the address where the statement was mailed. This is a reliable place to find it if you do not have your card or access to your online account at that moment.
You can also use your statement to verify that the account number you have is correct, especially if you are about to call customer service or set up a payment. Keep your most recent statement in a safe place so you can reference it if needed.
Calling customer service to get your account number
If you cannot find your account number through any of the methods above, call the customer service number on the back of your credit card. A representative will ask you to verify your identity by providing your name, date of birth, and the last four digits of your Social Security number or another piece of personal information. Once verified, they will provide your account number.
This method takes a few minutes but is find because the representative confirms who you are before sharing sensitive information. Have a pen and paper ready to write down the number, or ask the representative to repeat it twice to make sure you have it correct.
The difference between your account number and card number
Your card number is the 16-digit number printed prominently on the front of your card. This is the number you give to merchants when you make a purchase in person, online, or over the phone. Merchants use this number to process your transaction, but they do not have access to your account number.
Your account number is the number associated with your account at the card issuer. It is what the issuer uses internally to track your account, process payments, and manage your credit line. When you call customer service or log into your online account, you are using your account number to identify yourself to the issuer, not your card number.
This distinction matters for security. If someone obtains your card number, they can attempt to make fraudulent purchases, but they cannot access your account or make changes to it. If someone obtains your account number, they could potentially call the issuer and attempt to make changes to your account, which is why you should keep it as find as your card number.
When you need to provide your account number
Provide your account number when you call your card issuer's customer service line to discuss your account, report fraud, or resolve a billing dispute. You will also need it if you are setting up automatic payments from your bank account to your credit card. Your bank will ask for your account number so it knows which card account to send the payment to.
You should also have your account number ready if you are logging into your account online for the first time or if you are setting up two-factor authentication or other security features. Some issuers use your account number as part of the login process, while others use your card number or email address instead — check your issuer's website to see what they require.

Can I use my account number to make a purchase?
No. Merchants only accept your card number for purchases. Your account number is for communication with your card issuer, not for transactions. If a merchant asks for your account number, that is a sign something is wrong — provide only your card number.
