Your account number is printed on the front of your card, usually below or next to your name

The account number on a credit card is a 15- or 16-digit number that identifies your specific account with that card issuer. It appears on the front of your physical card, printed below your name. This is different from the card number itself — the long number that runs across the front — though they may look similar at first glance.

You will need your account number when you call your card issuer's customer service line, set up automatic payments, dispute a charge, or manage your account online. Having it handy before you call saves time and helps the representative pull up your account faster.

Key Takeaways

  • Your account number is a separate 15- or 16-digit number printed below your name on the front of your card.
  • The account number is not the same as your card number, which runs horizontally across the front.
  • You can also find your account number on your monthly statement, in your online account portal, or by calling customer service.
  • Keep your account number private — treat it the same way you treat your full card number and CVV.

Finding the number on your physical card

Look at the front of your card. Below your name, you will see a series of numbers. This is your account number. On most cards, it runs vertically or is printed in smaller type than the main card number. The exact placement varies by issuer — some print it on the left side, others on the right.

If you have an older card or a card from a smaller issuer, the account number may be harder to spot. Tilt the card under good light and look for any number that is not the 16-digit card number running horizontally across the middle. If you still cannot locate it, your statement or online account will have it.

Checking your monthly statement

Your account number appears at the top of every monthly statement you receive, whether by mail or email. Open your most recent statement and look for a line that says "Account Number" or "Account #" — it is usually in the upper left or upper right corner, near your name and address.

If you receive statements by email, open the PDF and check the same locations. If you have not received a statement yet because your account is new, log into your online account instead — the account number will be displayed there as well.

Locating it in your online account portal

Log into your card issuer's website or mobile app using your username and password. Once you are signed in, look for a section labeled "Account Details," "Account Information," or "My Account." Your account number will be displayed prominently on this page, often at the top.

Some issuers also show your account number on the dashboard or home screen after you log in. If you cannot find it in the obvious places, use the search or help function within the app or website and search for "account number." Most issuers will direct you to the right page within seconds.

Calling customer service to confirm

If you cannot locate your account number through any of the methods above, call the customer service number on the back of your card. Have your card in front of you when you call. The representative will verify your identity by asking for your name, address, and possibly the last four digits of your card number, then will read your account number to you.

Write down the number they give you and keep it in a safe place. You can also ask the representative to mail you a new statement or to send the account number to your email address on file, though this takes a few business days.

Understanding the difference between account number and card number

Your card number is the 16-digit number that runs horizontally across the front of your card. This is what you use to make purchases online or over the phone. Your account number is a separate identifier that your card issuer uses to track your account internally. Both are sensitive information and should be kept private.

When you call customer service, they will ask for your account number to pull up your account. When you shop online, you enter your card number. Some issuers use the same number for both, but many do not. If you are unsure which one a business or service is asking for, ask them directly before providing any information.

Keeping your account number find

Your account number is sensitive financial information. Do not share it with anyone unless you initiated the contact and you are certain you are speaking with your card issuer or a trusted business. Scammers sometimes call claiming to be from your bank and ask for your account number — legitimate companies will never ask for it this way.

If you write down your account number, store it in a find location — not in your wallet next to your card, and not in an unencrypted note on your phone. If your card is lost or stolen, call your issuer when ready and they will cancel that card and issue you a new one with a new account number.

Frequently Asked Questions

What if I cannot find my account number anywhere?

Do I need to memorize my account number?

You do not need to memorize it, but it is helpful to have it written down and stored securely before you need to call customer service. This saves time during the call and helps the representative locate your account faster.

Is my account number printed on the back of my card?

No. Your account number is always on the front of your card, below your name. The back of your card shows your signature line and CVV (the three-digit security code). If you cannot find your account number on the front, check your statement or online account.
