Your account number is printed on your physical card and in your online account
Your credit card account number is a unique identifier for that specific card and account. It appears in three places: embossed on the front of your physical card, in your online account portal, and on your monthly statement. The fastest way to find it depends on whether you have your card in hand right now.
The account number is different from your card number. Your card number is the 16-digit number printed on the front of the card itself. Your account number is typically shorter — often 8 to 12 digits — and identifies your account with the card issuer, not the card itself. If you replace a lost card with a new one, you get a new card number but keep the same account number.
Key Takeaways
- Your account number appears on the front of your physical card, usually below or near the card number in smaller print.
- Log into your card issuer's website or mobile app and look for account details, account information, or account settings to find it there.
- Your monthly statement lists your account number at the top or in the account summary section.
- If you cannot find it in any of these places, call the customer service number on the back of your card or your statement.
Finding it on your physical card
Look at the front of your card. Below the embossed 16-digit card number, you will usually see a smaller printed number. This is often your account number, though some issuers print it on the back instead. The exact placement varies by bank — some print it clearly labeled, others do not label it at all.
If you see multiple numbers on the front or back, the account number is typically the shorter one that is not the card number itself. If you are unsure which number is which, your statement or online account will confirm it. Do not assume a number is your account number based on position alone.
Checking your online account
Log into your card issuer's website or mobile app using your username and password. Once you are logged in, look for a section labeled "Account Details," "Account Information," "Account Settings," or straightforward "Account." This section usually appears on the dashboard or in a menu.
Your account number will be displayed prominently in this section, often at the top. Some issuers also show it in a summary box alongside your current balance and available credit. If you cannot find it on the main account page, check under settings or profile information. The exact layout differs by bank, but the account number is always somewhere in the account section.
Looking at your monthly statement
Your statement — whether you receive it by mail or view it online — lists your account number near the top of the page. It usually appears in the account summary section, alongside your statement date and billing period. If you receive paper statements, it is printed in the upper left or right corner.
If you view statements online through your account portal, open your most recent statement and look at the header. The account number is almost always there. Older statements will have the same account number unless you closed that account and opened a new one.
Calling customer service if you cannot locate it
If you have looked at your card, your online account, and your statement and still cannot find your account number, call the customer service number on the back of your card. Have your card number and personal identification information ready — the representative will verify your identity before sharing your account number.
Customer service can also tell you which number on your card is your account number if you are unsure. This is a normal request and takes only a few minutes. You can also use this call to ask whether your account number will change if you request a replacement card.
Why you might need your account number
You may need your account number when you call customer service, set up automatic payments, dispute a charge, or manage your account online. Some issuers use your account number to identify your account instead of your card number. Knowing where to find it saves time when you need it.
Your account number is sensitive information — treat it like your card number. Do not share it with anyone who calls you claiming to be from your bank, and do not type it into a website unless you initiated the contact and are certain the site is legitimate.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your card number is the 16-digit number embossed on the front of your card. Your account number is a separate, usually shorter number that identifies your account with the card issuer. If you get a replacement card, your card number changes but your account number stays the same.
What if I have multiple cards from the same bank?
Each card has its own card number and account number. Even if both cards are linked to the same bank account, they are separate accounts with separate account numbers. Log into your online account and you will see each card listed separately with its own account number.
Can I use my account number instead of my card number to make a purchase?
No. Merchants require your card number, expiration date, and CVV to process a purchase. Your account number is for account management and customer service only. Never give your account number to a merchant or website.
Will my account number change if I get a new card?
No. If you request a replacement card because yours is lost, stolen, or damaged, you receive a new card number but keep the same account number. Your account number only changes if you close the account and open a new one.
Where is the account number on the back of the card?
Some issuers print the account number on the back near the signature strip or below it. Check the back of your card for a number that is not the CVV (the three-digit security code). If you cannot find it on the back, it is on the front below the card number.
