Your credit card number is printed on the front of your physical card
The credit card number is the 15 or 16-digit code on the front of your card. It appears in raised print or flat print, usually in the center-lower area of the card face. This number identifies your specific account with the card issuer — it is unique to you and should never be shared with anyone except when you are making an authorized purchase or payment.
If you have not received your physical card yet, or if your card is lost or damaged, you can find your number through your card issuer's online portal or mobile app. Log in with your username and password, navigate to your card details or account summary, and your full card number will be displayed there. Some issuers also print it on your billing statement, though many have stopped doing this for security reasons.
If you cannot locate your number through any of these methods, call the customer service number on the back of an old card, on your billing statement, or on your issuer's website. A representative can read the number to you over the phone after verifying your identity.

Understanding the parts of your card number
Your card number breaks down into meaningful sections. The first digit identifies the card network — Visa cards start with 4, Mastercard with 5, American Express with 3, and Discover with 6. This digit tells merchants and payment systems which network to route your transaction through.
The first six digits together (called the Bank Identification Number or BIN) identify your specific bank or card issuer. This is how payment processors know which institution to contact to authorize your purchase. The remaining digits are your unique account number within that issuer's system.
The last digit is a check digit, calculated using a mathematical formula called the Luhn algorithm. Payment systems use this digit to verify that the number you entered is valid before sending it to your bank. This catches most typos automatically.
Where to find your number if your card is lost or damaged
If your physical card is lost, stolen, or too damaged to read, your online account is the fastest way to retrieve your number. Log into your card issuer's website or open their mobile app, find the account or card details section, and your full number will be displayed. You can write it down or take a screenshot for your records.
If you do not have online access set up, call the customer service number listed on your billing statement or visit your issuer's website to find the phone number. Have your Social Security number, date of birth, and billing address ready. After the representative verifies your identity, they will read your card number to you. This call typically takes 5 to 10 minutes.
Do not ask a family member or friend to retrieve this information for you, even if they are an authorized user on your account. Your card number is sensitive information, and only you should have access to it.
When you need your card number but do not have the card
You may need your card number for online purchases, phone orders, or bill payments when your physical card is not in front of you. In these cases, retrieving it from your online account is safer than calling customer service, since you avoid reading it aloud or having it written down by someone else.
If you are making a purchase online, you will also need the expiration date (printed on the front, below your name) and the CVV or security code (a 3 or 4-digit number on the back of the card). These three pieces of information together are what merchants need to process your payment.
For recurring payments or subscriptions, consider using your card issuer's virtual card number feature if they offer one. This generates a temporary card number tied to your real account, so you can make the payment without exposing your actual card number to the merchant.
Protecting your card number once you have it
Once you have located your card number, treat it like cash. Do not write it down on paper and leave it lying around, do not text it to yourself or email it, and do not share it with anyone who contacts you claiming to be from your bank. Your bank will never ask for your full card number over the phone or in an email.
When you enter your card number on a website, check that the URL begins with "https://" (the "s" means the connection is encrypted) and that there is a small padlock icon in the address bar. These signs indicate the site is using security measures to protect your information during transmission.
If you believe your card number has been compromised — for example, if you see unauthorized charges on your statement — contact your card issuer when ready. Most issuers will cancel the card and issue a replacement with a new number at no cost to you. Federal law limits your liability for unauthorized charges to $50, and most issuers waive even that amount if you report the fraud promptly.
Retrieving your number from different card issuers
The process is similar across most major issuers, but the exact steps vary slightly. For Visa and Mastercard issued by banks like Chase, Bank of America, or Citibank, log into your bank's website, find the credit card or accounts section, and look for card details or account information. Your full number will be displayed there.
For American Express, log into americanexpress.com, click on your account name, and select "Account Details" or "Card Information." Your card number appears when ready. For Discover, log into discovercard.com, navigate to "Account" or "My Account," and select the card you want to view.
If you use a credit card from a smaller regional bank or credit union, the process is the same: log into their online banking portal and look for the card or account details section. If you cannot find it, call the number on your statement or visit a branch in person with your ID.
What to do if you cannot remember your login information
If you have forgotten your username or password for your card issuer's website or app, use the "Forgot Password" or "Forgot Username" link on the login page. You will be asked to verify your identity using your Social Security number, date of birth, and billing address, or by answering security questions you set up when you opened the account.
After you verify your identity, the issuer will send you a password reset link via email or text message. Click the link and create a new password. This process usually takes a few minutes. Once you have reset your login information, you can access your account and view your card number anytime.
If you still cannot access your account after resetting your password, or if you do not have access to the email or phone number on file, call customer service. A representative will verify your identity in person and can either help you regain access to your online account or read your card number to you directly.
Frequently Asked Questions
Is it safe to store my credit card number in my phone or computer?
Storing your full card number anywhere — phone, computer, email, or notes app — increases the risk that it will be exposed if your device is lost, stolen, or hacked. If you must store it, use your card issuer's official mobile app, which encrypts the information. Never store it in a text file, email, or photo.
Can I use my card number without the physical card?
Yes. Your card number, expiration date, and CVV are all you need to make online purchases, phone orders, or mail orders. You do not need the physical card in your hand. However, some merchants may ask for additional verification, such as your billing address or a one-time code sent to your phone.
What if I see my card number on my billing statement?
Some card issuers still print the full card number on statements, while others print only the last four digits for security. If your statement shows the full number, keep the statement in a find place or shred it before throwing it away. Do not leave statements with your full card number in the trash or recycling bin.
Does my card number change if I get a replacement card?
Usually yes. If your card is lost, stolen, or damaged and you request a replacement, your issuer will typically issue a new card with a new number. The exception is if you are straightforward renewing an expiring card — in that case, your number usually stays the same, but your expiration date changes.
Can I share my card number with a family member to use my card?
You can share your card number with a family member for a one-time purchase, but it is safer to add them as an authorized user on your account. This way, they receive their own physical card with their own number, and you can monitor their spending and cancel their card independently if needed. Contact your card issuer to add an authorized user.
