Your credit card account number is the 15 or 16-digit code printed on the front of your card, unique to that specific card and account
The account number appears in two places on a physical card: embossed (raised) across the front, and printed again below it in smaller digits. On a digital or mobile wallet version, you can usually find it by opening your card details in your bank's app. The number identifies your account to the card issuer — the bank or financial company that issued the card — and is what they use to process charges, payments, and refunds tied to that card.
This is different from your routing number, which belongs to your bank as a whole. Your account number belongs to this specific card account. If you have two credit cards from the same bank, each has its own account number.
Key Takeaways
- A credit card account number is the 15 or 16-digit code on the front of your card that identifies that specific card and account to your bank.
- You will see the number embossed on the card itself and printed again below it, or in your bank's mobile app under card details.
- You need your account number to make payments, dispute charges, track refunds, or contact your card issuer about that specific card.
- Never share your full account number with anyone except your bank or a merchant you trust to charge the card.
Where the account number sits on your card
On the front of a physical credit card, the account number runs horizontally across the middle or lower portion of the card face. The digits are raised (embossed), which is why you can feel them if you run your finger across the card. Below the embossed number, the same digits are printed in smaller, flat text — this printed version is what card readers and payment terminals scan.
The account number is always separate from other numbers on the card. Your expiration date appears to the right of the account number, and your CVV (the three-digit security code) is on the back. Your name is printed above or below the account number.
If you use a digital wallet — Apple Pay, Google Pay, Samsung Pay — your card details, including the account number, are stored in your phone or device. Open your bank's app or your wallet app, find the card, and tap "Details" or "Card Information" to see the full number.
Why you need your account number
Your card issuer uses your account number to connect any transaction or payment to your specific account. When you make a purchase online or in a store, the merchant sends your account number to your bank to process the charge. When you make a payment to your card, you provide the account number so the bank knows which account to credit.
If you are tracking a refund from a merchant, you will need your account number to tell the merchant where to send the money back. If you dispute a charge or report fraud, your bank will ask for your account number to pull up the right account and transaction. If you call your card issuer with a question about your account, they will ask you to verify the account number before discussing anything.
How to find your account number if you don't have the card
If your card is lost, stolen, or simply not in front of you, your bank's website or mobile app will show your account number. Log in to your online banking portal or open your bank's app, navigate to the credit card section, and look for "Card Details" or "Account Information." The full account number will be displayed there.
You can also call your bank's customer service number — usually on the back of another card you have, or on your monthly statement — and a representative can read your account number to you after you verify your identity. Some banks also send account numbers in welcome letters or statements, though for security reasons many no longer do this.
If you have an old statement or bill from that card, the account number is printed at the top or in the account details section.
Security: what to do with your account number
Your account number is sensitive information. Share it only with your bank, a merchant you are paying directly, or a service you trust to charge the card. Do not type it into unsecured websites, email it to unknown addresses, or read it aloud in public.
If someone calls claiming to be from your bank and asks for your account number, hang up and call your bank directly using the number on your card or statement. Banks do not ask for account numbers unsolicited. If you believe your account number has been compromised — for example, you see charges you did not make — contact your card issuer immediately to report fraud and request a new card.
Account number versus other card numbers
Your credit card account number is not the same as your routing number or your bank account number. Your routing number identifies your bank as a whole and is used for wire transfers and ACH payments. Your bank account number is for your checking or savings account, separate from your credit card account. Your CVV is a three-digit security code on the back of the card used for online purchases, but it is not your account number.
If you are setting up a payment or transfer and need to know which number to use, the form or website will tell you. For credit card payments, you will need your account number. For bank transfers, you will need your routing number and bank account number.
Frequently Asked Questions
Can I use just part of my account number for security?
Yes. Many banks and merchants will ask you to verify only the last four digits of your account number for security purposes. This confirms you have access to the card without exposing the full number. If a representative asks for your full account number, you can ask if the last four digits are sufficient instead.
What if my account number has changed?
If your card was lost, stolen, or compromised, your bank will issue a new card with a new account number. The old account number becomes inactive. Any recurring charges (subscriptions, automatic payments) tied to the old number will need to be updated with the new account number to keep working.
Is my account number the same on all my statements?
Yes. Your credit card account number stays the same on every statement and transaction for that card, unless the card is replaced. If you get a new card due to expiration or fraud, you receive a new account number.
Do I need my account number to check my balance?
No. You can check your balance by logging into your bank's app or website, calling the automated customer service line, or texting your bank — these methods use your login credentials or phone number, not your account number. You only need the account number when making a payment or disputing a charge.
